There has never before been a published book of slot machine reel strip combination with complete payout statistics-until now. And what a book-nearly 300 total pages! The heart of the Handbook consists of over 200 computer-generated charts which mathematically analyze various combinations of old factory-standard reel strips.

Slot machines are referred to as slots, pokies, 1-arm bandits, fruit machines and poker machines. Players will place wagers in the form of coins (or virtual coins if it is an online slot) in order to spin the reels of the game. Any slot machine will have a minimum of 3 reels and players can start spinning these reels by pulling a lever (or clicking on Spin). The symbols on the reels will start to spin until they stop. When they stop, players will be rewarded according to the combination of symbols they achieve on the payline. The payline is a virtual line on which players must get certain symbols in order to get paid.


Players will be paid based on the bet they have placed, the combination of symbols, and the paytable of the game. The paytable is a table that shows players the different combinations and their respective rewards. This paytable is usually found at the top above the reels of the slot machine or on the game screen itself – whether land or online-based. The symbols appearing on these reels are usually bars, cherries, bells, watermelon, and sevens, this is why they were called fruit machines. Other advanced slots might have a certain theme. For these games, the symbols will be inspired by that theme. For example, Thunderstruck is an online slot which is themed around Thor and the Norse gods. On this game’s reels, players will see symbols that include Thor, Thor’s Hammer, and Odin among other related symbols.

Slots History

The history of the first slot machine dates back to 1895. The father of the first slot machine was Charles Fey, whose original slot machine had poker symbols on its three spinning reels. The symbols also included hearts, horseshoe, bells, and spades. Since the game only had 3 reels automatically, it was easy to make the game payout for the winning combinations. The game paytable was available at the top and it showed players the different winning combinations. The highest combination paid 50 cents when players got 3 bells on the win line.


In 1891, Sittman and Pitt invented another form of slot machine. This new machine looked a lot like the early version of slots that can still be found to this day. The game included five reels and 50 cards with a poker game theme since players were paid according to the poker hand they formed. This is why they were called poker machines. Players would start the game by putting a nickel into the game’s slot and by pulling the lever in order for the reels to spin so they could get a poker hand. Most of these machines used to pay players in the form of gifts such as cigars, drinks, or food or other things that were sold at the pub or bar where it was being offered. In order to increase the odds of the house and make it hard to get a poker hand like a Royal Flush, the game did not have a 10 of Spades or a Jack of Hearts.

In 1907, Herbert Mills invented another machine that was called Operator Bell and by 1908 these slots were installed in every bowling alley, cigar store, or salon. One of these original “Liberty Bell” slots can still be found in a Reno Restaurant in Liberty Bells Saloon.

Another great development occurred in 1963 when Bally invented the 1st electromechanical slot machine called The Money Honey. This was the first slot to have a bottomless hopper and it offered automatic payouts as well. The biggest reward that could be claimed was 500 coins. This machine was one of the reasons behind the skyrocketing rise of electronic gambling. Reel Em was the first-ever video slot that offered players bonus rounds.

In the 1990’s multi-line slots made an entrance to the scene. These games had more than one winning line. This meant that players could claim payouts according to combinations on more than one line aligned on the game’s screen. With the emergence of online gambling, slots were one of the first games to be adopted and transformed into online games. They developed quickly and can now offer up to 100 lines and 1024 ways to win. They also offer players a lot of bonuses in the form of wilds, scatters, and progressive jackpots.

How to Play Slots

Slot machines can be found at every gambling venue, whether online or land-based. The online gambling world has fewer restrictions in terms of technology and development, therefore players will find a wider array of slot machines than those found at land-based gambling venues. We are going to discuss the gaming procedure for both online slot machines and land-based slots:

For Land-Based Slots:

For land-based slots, players will have to buy bar-coded coins, quarters or other cash values the game accepts. Usually, players will see the cash value the game accepts written on the game itself. After players enter the coin or cash in the game’s slot, they will pull down the lever or press the spin button, causing the reels of the slot to spin. The symbols on these reels are usually themed around fruits that are accompanied by bells, sevens, and the usual one bar, two bar, and three bar symbols.

After the reels stop spinning, players will be rewarded if they have a winning combination on the game’s win line. Players can find out the combinations that would make them eligible for a win at the game’s paytable. This paytable can be found at the top of the reels, or these days on the game screen itself. It will show the different combos and their rewards.

There are also slot machines that resemble video slots that can be found online. (Some can even be found with the same features online.) These video slots usually have a touch screen that players will use in order to control the game like in video poker.

For Online Slots:

Players who want to enjoy this game at an online casino will have to follow another gaming procedure. For online slots, players will first choose the game, then they will choose their wagers. Choosing the wagers, whether a classical or a multi-line video slot, includes 3 options:

  • Choose the number of lines that players want to activate by placing their stakes on.
  • Choose the coin value that players want to use to place wagers and get rewards.
  • Choose the number of coins they wish to place on every activated line. All of this creates the wager. The total amount of their bet will be seen under the Bet Cell.

After placing the wager, players will be able to start the game by clicking on Spin. It is usually found under the reels in the game’s control panel in between or next to the wagering options that were mentioned above. The symbols will spin and, after they stop spinning, players will be paid according to the paytable, their bet, and the winning combination. The paytable can also be viewed at the top or as players click on “View Pays” or Paytable that is found somewhere on the game’s screen.


Slots Rules

The rules differ from one slot machine to another. Each slot machine will have its own set of rules printed on the game itself or, in the case of online slots, players can view them by clicking on “Game Rules.”

Max Bet Only Triggered Bonuses:

Some bonuses and jackpots will not be triggered or activated unless players have placed the maximum wager.

Wild Symbols:

Wild symbols differ from one game to another and can substitute for any other symbol the slot machine has. These wild symbols will not replace other bonus or scatter symbols.

Triggering the Jackpot:

The jackpot is triggered when players get a certain combination of symbols on any of the winning lines of the game. It can be found at the paytable.

Scatter Symbols:

Scatter symbols are special symbols that reward players generously in the form of scatter payouts. They can also trigger free spins. Free spins mean players will get a number of spins on the slot for game free. They are usually triggered when players get three scatters on the reels or three of the bonus symbols on the payline.


Apart from these rules, there are also some rules of etiquette that players should follow when playing at a land-based casino or a venue that is offering these slots.

Players can play on two slot machines side by side provided that the gambling venue or the casino is not crowded. If it is crowded and there are players waiting to be seated, the attendant will ask players who are playing on two slots to end one of the sessions.

Some players prefer to keep rapidly clicking on the buttons thinking that it gives them better luck. This is usually frowned upon because it causes the buttons to wear out quickly and causes a lot of disturbance to other players in the casino or the gambling venue.

Players who want to watch another player spinning the reels should leave one chair between them and the players unless they plan to play on the slot machine right next to that person. If they do not do that, an attendant will approach them and ask them to move away.

It is ok to celebrate when you get a big win or hit the jackpot, provided that you do not celebrate for too long. Also, when you get a big win, it is customary in certain parts of the world to tip the attendant who is getting the payout for you. It’s common etiquette.

Lastly, if you spot a slot machine that has a leaning chair on it, it is advised to leave that slot machine alone. It signals someone is still playing at the slot machine and he had to go to the bathroom or get something to drink and will be back shortly, it is courteous to leave it for a maximum of 10 minutes before you move the chair and take a seat.

Slots Odds

Slots are usually programmed to payout 82 to 98 percent of what was wagered in the form of winnings. This percentage is known as RPT (Return to Player) or the Theoretical Payout Percentage. The minimum RTP for every slot machine depends on the regulations and laws of the state or country. In Nevada, for example, the minimum percentage is 75 percent, in New Jersey it is 83 percent and in Mississippi, it’s 80 percent.

The winning combinations and patterns on a slot machine, the amount it pays, and the frequency of these payouts are carefully calculated and selected so they pay a specific fraction of money to the casino or the house while giving back the rest to the players. For example, a spin on a slot machine costs one dollar and it has an RTP percentage of 95. It can be calculated that over the long term, for example after one million spins, the game is going to give back $950,000 to players from the 1,000,000 dollars they have put into the slot. The house or the operator will keep the remaining $50,000.


The RTP is not the only important statistic in slots as the percentage of every payout on the game’s paytable is also important. For example, in any slot machine that has 12 different rewards in the paytable, the probability of every reward equaling 0 percent except the jackpot can be quite deceptive. If the jackpot win is 4000 times the wager, then it would happen 1 time every 4000 spins and would make the game have an RTP of 100 percent, despite being a very dull game.

The table of the probabilities for any slot machine is called the Paytable & Reel Strips sheer, also known as PARS. PARS helps players understand the psychology of the slot machine. For instance, if the game has 13 payouts that range from 1:10 up to 2400:1 it will show that the 1:1 payout would happen once every 8 spins, the 5:1 would happen once every 33 spins while the 2:1 payout will happen once every 600 spins. The PARS sheet is usually confidential and developers and manufacturers never post them; however, it is possible to find the PARS sheet of any of your favorite games posted online. Despite this, they are not of any real value to players as slot machines usually have 8 to 12 different programs that have varying payouts.

Slot machines are also known for the “Taste.” The Taste refers to a small amount of money the game pays every few spins to those who are seated at a slot machine to keep them engaged in the game. The logic is simple: if players keep losing their bets without winning any back, they will eventually grow bored and leave the game. The taste is usually the 1:1 or the 2:1 payout.

Slots Strategy

Slot machines are games of luck, so there are no strategies or techniques to implement. On the other hand, there are some tips and suggestions that may be quite useful for any player who is looking forward to spinning the slots:

Stick With Slots With a Low Jackpot:

How To Make Slot Machine Reel Strips

If you are a land-based casino player, you will notice that the slot machines that offer millions in jackpots are not that popular because the chances of hitting the jackpot are very slim. This is why you should stick to slot machines that have a jackpot in the $1,000 range since you have a better chance of triggering it. These smaller jackpot slots are known for paying out better rewards and more frequently, too.

Know When You Should Move On:

Like any other casino game, you might find yourself on a losing streak. When that happens you should just move on or stop playing or perhaps go to another slot to change your luck.

Quit While You Are Ahead:

If you have been on a winning streak or have just hit a jackpot, it is a good idea to cash in your winnings and leave. The more you play the bigger the chance you might lose what you won (or at least a big chunk of it). Like any casino game, you should quit while ahead.

Work According to a Betting Pattern:

You should always follow a wagering pattern that will help you earn rewards. For example, always start with the minimum wager possible and, if you lose, up it up a notch and keep increasing the bet after each spin. When you win, do the opposite. The + / – betting pattern is not guaranteed as there are no guaranteed betting patterns for slots because it is 100 percent random, but this can help increase your odds.

Placing the Maximum Wager:

Although this contradicts the last tip, it is another way of playing. The aim is to place the highest wager so you can earn high rewards. This is essential in online video slots as some bonuses cannot be triggered if players do not place the max bet.

There are also some misconceptions we have to clarify:

  • Playing the game faster will not increase the chances of winning.
  • Clicking on the spin or pulling the lever rapidly will not affect the outcome of the slot. They are all the same.
  • Each spin is independent, so the game will never be “due to hit”.
  • When someone wins a great payout on a slot machine that you left does not mean that you missed that payout. There is a big chance that you wouldn’t have hit the same payout because you would not have pulled the lever at the same fraction of a second that the player did.

Pro’s Perspective: Slot Strategies and Tips

With John Grochowski

Modern slot machines are multimedia technological marvels complete with animation, sound effects, and sometimes even video clips from movies and television shows.

While three-reel slots still exist, the majority in both live casinos and online casinos have five reels, and sometimes have six, seven, or more. Instead of one payline, modern video and online slots usually have 20, 30, 40, or more pay lines. Some don’t even use pay lines at all, making any combination of the same symbols connecting from left to right a potential winner, even if they’re not on a line as such.

During regular play, you may win a trip to a bonus event during which you have a chance to win money without making any additional wagers. Here are a few of the most common bonus types.

Free spins

You could win a specified number of free reel spins. Many free spin bonuses are played on the same reels as the main game and it’s possible to win any of the usually available prizes. Sometimes, the main reels fade from the screen and are replaced by bonus reels with different symbols and different winning potential.

For example, in the last few years, games have been introduced in which the lowest-paying symbols are removed from the bonus reels. It’s still possible to win nothing on a bonus spin, but the frequency of big winnings are increased.

Wheelspins

The original wheel spin game, Wheel of Gold, was introduced in the mid-1990s and it led to the ever-popular Wheel of Fortune slots. Since then most slot manufacturers have incorporated wheel spins.

In a wheel spin bonus, you see a wheel divided into prize segments. On some, all prizes are credit amounts, but some wheels offer credit multipliers, progressive jackpots, and trips to other bonus events. You start the wheel spinning, then hope it lands on a big-paying space.

Pick’em events

The reels are replaced by a different scene. Some have included aliens in hiding spaces, dancing gift-wrapped boxes, dishes on a Chinese menu, fishermen on a pond, and much more.

You touch the screen to choose an icon, and the item then reveals a credit reward for you to collect. On some pick’em events, you make just one choice. On others, you keep picking until you choose a bonus-stopper symbol.

Personal preference

All these bonus events are designed to make the games interactive and fun to play. How much they contribute to the overall payback differs from game to game and manufacturer to manufacturer, but as much as 40 percent of the overall return may come from bonuses.

Free spin games tend to be more volatile with the potential for bigger wins offset by the possibility of spins that bring no credits. Pick’ ems are used in what the slot industry calls “entertainment” games in which it’s larger goal is to add fun and extend your play rather than to offer big wins.

Ultimately, which is best for you comes down to personal preference. Do you like pick’em entertainment or do you want to keep those reels spinning?

If you have a slot machine or you have bought one old used vintage slot machine and want to have some fixes to get it work then obviously you will think you need a machine technician. Many of you will even think of taking it to some repair station to get things done. But here in the guide you will find some of the repairs that you yourself can do with your slot machine and you need not need to join machine technical repair training school.

Like any other machines Slot machines too are a blend of electronic and mechanical components, that wear with age and require routine repairs. Before you begin to repair yourself do note that every slot machine that you have purchased whether old or new comes with installation and user guide manual. You need to read that many a times until you are familiar with each components and parts of the slot machine and understand thoroughly as how the slot machine works.

In your guide to repair slot machines you will find some common repairs that can be carried out by you, some videos to watch as well. If your slot machine has some complex issue then obviously you require a qualified technician.

Changing the Top Florescent Light

The top florescent light bulb is easily changed by following these simple procedures. The replacement bulb is an F15T8/CW 18″ 15 Watt bulb which is available at most hardware and department stores or may be purchased online at Ebay or Amazon or realslotmachinesforsale under the category ‘parts of slot machine’.

  • Open the main slot machine door and ensure the door is fully open. Turn off the power to the slot machine. The power switch can be found with the main door open about midway down on the right side just inside the machine.
  • If the machine is equipped with a top ticket printer, you must pull the bottom of the printer out far enough to see where the ticket paper is located, and note the area large enough to place a couple of your left fingers under.
  • Remove the top metal trim strip which is a cover plate to the right of the ticket printer and/or is located along the bottom of the top glass. There are a couple of clips on the back of the metal trim strip that fit into notches on metal bracket which holds the top glass. The metal trim strip should be lifted upwards and outwards to remove.
  • Once the metal trim strip is removed, the next step is to remove the top glass. Note that some top metal trim strips have a slot in the top that holds the top glass and they must be removed very carefully as to not damage or drop the top glass.
  • You can now see the top glass is held in place by usually two or three clips that rise above the metal bracket behind the top metal trim strip. Now slowly lift up on the top glass from both bottom edges until the top glass until it is high enough to gently pull it forward and allowing it to slide down and away from the top track and clips holding it in place.
  • Once the top glass has been removed, put it somewhere where it will not get knocked over or broken. You will see the florescent bulb in the middle of the top box area of the machine. Care should be taken removing the bulb as it may be very hot. Remove the old bulb by twisting the florescent tube about a quarter to half turn allowing the two prongs on the bulb to slide out of the fixture on both sides of the bulb.
  • Remove and discard the old bulb. To install the new bulb, align the two prongs on each side of the florescent tube with the slits on each fixture in the top box of the slot machine. Twist the bulb into place normally using about a quarter to half of a turn. If the bulb is not secure or aligned, repeat the procedure.
  • If your slot machine is an IGT S Plus machine, it is equipped with a florescent bulb starter. Then you can replace the starter when replacing the florescent light bulb. The starter is an FS-U Universal Starter. They are available at most hardware and department stores or may be ordered online too. The starter for the top florescent bulb on an IGT S Plus machine is located directly behind the florescent bulb fixture on the left side of the slot machine in the top box area.
  • It is replaced by twisting about a quarter to half a turn as it is held in place with a bayonet type mount. Remove the old starter and discard. Replace with a new FS-U Universal Starter by aligning the two pins on the bottom of the starter with the notches in the starter receptacle, pushing it up into the starter socket, and then twisting it a quarter to half a turn into place.
  • Prior to re-installing the top glass, turn the power switch on the right inside of the machine on to verify the bulb works properly. If it does not, turn the power off and check that the bulb is properly installed and secure. If replacing a starter, check that it is also properly installed and secure.
  • After verifying the bulb is working, it is now time to replace the top glass. If your slot machine has a top ticket printer, ensure the ticket printer is still pulled out so you can place your fingers in the opening while replacing the top glass.
  • Carefully and slowly lift up the top glass placing each hand under the bottom of the top glass. Slide it into the upper edge track on the top box of the slot machine carefully lifting it so it slides into the tracks while being able to push the top glass back far enough to clear the two or three raised clips on the metal bracket where the top glass holding track is located.
  • Gently and slowly lower the top glass behind the clips so as to allow them to hold the glass in place. If properly secured, the top glass will not be able to slide down or out of its position. Keep a secure hold on the top glass until you are certain it is secured in the proper position.
  • Replace the top metal trim strip by aligning the two or three hooks the back through the metal bracket that supports and holds the top glass. Once the hooks on the back are in place, gently push the top metal trim strip down and it should snap into place. If you have a slot machine with a top ticket printer, close it tight into position. Close the main slot machine door and you are ready to play.

Changing the Belly Glass Florescent Light

The belly glass florescent light bulb is easily changed by following these simple procedures. The replacement bulb is an F15T8/CW 18″ 15 Watt bulb which is available at most hardware and department stores or may be bought online as spare parts of slot machine.

  • Open the main slot machine door. Turn off the power to the slot machine. The power switch can be found with the main door open about midway down on the right side just inside the machine.
  • Facing the slot machine door, look on the right side of the door just around from bill acceptor area. You will see a knob sticking out that is approximately the size of the end of a regular pencil. This knob when pulled out releases the slot machine belly glass assembly (belly door) to fold down so the bulb can be accessed.
  • There are a couple of very important thing to remember prior to pulling this knob to release the belly door. First try pulling gently on the knob. If it does not allow you to pull out and you have a lock installed directly above it, the lock must unlocked in order to allow the release knob to pull out. When pulling out the release knob, be ready for the belly door to fold down.
  • Most of the time you must lightly pull on both sides of the belly door to get it to fold down, however always place your hand under it so it does not fall down too quickly causing the belly glass to break or crack.
  • Once the belly door is in the down position, you will see the access to the florescent bulb bracket that is held in place by a small Phillips screw. Remove the screw and place it the coin tray so it will be handy when you need it after replacing the bulb.
  • The long metal bracket that holds the florescent bulb must be slid slightly right or left so as to be able to lift it out of the belly door. Gently lift the metal bracket with florescent bulb out of the assembly far to be able to turn it over to replace the bulb. Be cautious as the bulb could still be hot!
  • Grasp the metal bracket holding the florescent bulb and remove the old bulb by twisting the florescent tube about a quarter to half turn allowing the two prongs on the bulb to slide out of the fixture on both sides of the bulb.
Machine
  • Remove and discard the old bulb.To install the new bulb, align the two prongs on each side of the florescent tube with the slits on each fixture that is on each side of the new bulb. Twist the bulb into place normally using about a quarter to half of a turn. If the bulb is not secure or aligned, repeat the procedure.
  • Now turn the metal bracket that holds the newly installed bulb over and back into position in the belly glass assembly. Slid the bracket slightly right or left into position and replace the small screw which holds the metal bracket in place.
  • If your slot machine is an IGT S Plus machine, it is equipped with a florescent bulb starter. So you need to replace the starter a well when replacing the florescent light bulb. The starter is an FS-U Universal Starter. They are available online and you can purchase one.
  • The starter for the belly glass florescent bulb is located on the back of the main slot machine door on the lower right hand corner as you face the back of the door.
  • It is replaced by twisting about a quarter to half a turn as it is held in place with a bayonet type mount. Remove the old starter and discard. Replace with a new FS-U Universal Starter by aligned the two notches on the bottom of the starter, pushing it into the starter socket, and then twisting it a quarter to half a turn into place.
  • Prior to closing the belly glass door, turn the power switch on the right inside of the machine on to verify the bulb works properly. If it does not, turn the power off and check that the bulb is properly installed and secure. Also check to ensure the starter is properly installed and secured.
  • Lift the belly glass assembly up and push it into place in the slot machine door. Ensure the belly glass door snaps into place and the knob on the side of the door is in its normal position. It is spring loaded so as to not allow the belly glass assembly to open unless it pulled. If the belly door appears to be in place, pull on both sides of the belly door to make sure it is locked and secure.
  • If you unlocked the lock above the knob, re-lock it. Close the main slot machine door and you are ready to use your slot machine.

Changing the Push Button Bulbs

All of the slot machine’s push button lights such Play Max Credits, Spin Reels, Bet One Credit, etc. are easily replaced by following this simple procedure. The replacement bulbs are #161 on IGT S2000 machines and #555 on IGT S+ machines and may be purchased from online stores.

  • Fully open the slot machine door. Look on the backside of the door. Each push button will extend down from the shelf on the door and will have a small wire bundle going to it. Identify which push button bulb needs to be replaced.
  • Carefully pull down on the bottom of the push button area that is normally white and is where you will see wiring connected. Using your thumb and two fingers, pull straight down and the bottom portion of the push button should snap out.
  • You will now be able to see the bulb in the top area of the lower push button assembly. Use caution as the bulb may be very hot. Pull the wedge bulb out and discard it. Notice the slot in which the bulb located.
  • Place a new bulb in the slot noting the direction of slot ensuring the new wedge bulb is inserted so as to line up in the slot. Push the new bulb into place.
  • Replace the bottom of the push button assembly by inserting it into the top portion of the push button assembly. The bottom portion will snap into position. Ensure that none of the wire connections have been accidentally knocked loose on the bottom of the push button. Note the push button light will not illuminate until the slot machine door is closed. Close the main slot machine door and you are ready to play.

Changing the Small Panel Lights

The small panel lights that illuminate the denomination amount and other areas behind the glass are easily changed. For denomination amount lights on the IGT S2000, a #73 bulb is needed and a #86 bulb is needed on the IGT S+ slot machines. They may be bought online from slot machine selling sites.

Here it is described as how to change the lights behind denomination amounts such as .25 Cents. Other small panel light bulbs are changed in the same manner.

  • Fully open the slot machine door. Look on the backside of the door. Note the location where the denomination amount would be located near the center just below the slot machine’s center glass. The area will appear to be flat with a small bulb holder projecting out that is slightly larger in diameter than a regular pencil and is flat on two or four sides.
  • This bulb holder is removed by simply twisting it a quarter to half a turn and then gently pulling it out of its socket. It is held in place by somewhat of a bayonet type mount.
  • Once the bulb holder is removed, pull the wedge bulb out of the socket and discard the old bulb. Caution should be taken as the old bulb may be very hot. Replace the bulb by firmly inserting a new bulb into the socket of the bulb holder being careful to align the wedge bulb correctly into the slot.
  • Take the bulb holder and look for two notches on each side of the opening where the bulb holder is inserted. Note there are two notches on the bulb holder. Align the notches inserting the bulb holder into the panel.
  • Gently twist the bulb holder about a quarter to half a turn to lock it into place. Verify the bulb is illuminating, and if not repeat the procedure using a different new bulb. Now close the main slot machine door and ready to use.

Cleaning Your Slot Machine

This is common thing and all you need is usually nothing more than a damp cloth to clean the exterior cabinet of your slot machine. Never use any abrasive or ammonia based cleaners on the cabinet of the machine.

The slot machine top, center and belly glasses may all be cleaned on the outside by using a window cleaner. However if you own a slot machine with a frosted exterior glass or one that has any exterior decorated markings such as stars, a window cleaner should not be used as the cleaner may damage the exterior images. Care should be taken cleaning interior glass as a cleaner and cloth may damage labels or markings.

The inside of the slot machine should not require cleaning other than occasionally removing dust. This can normally be done with a damp clean cloth, however ensure the power switch has been turned off prior to cleaning.

When wiping dust inside your machine, be careful not to loosen any wires or connections. Do not use a damp cloth on the face of your reel strips as the playing symbols on the reel strips could come off or become torn. Also be very careful not to touch the back side of your reel strips with a damp cloth especially if the back sides of the reel strips are black. This can cause damage to this type reel strip.

When your Slot Machine Doesn’t Power On

Royal Reel Slot Machine

When you get a slot machine and wish to locate or set up at your place, determine the household 120V AC outlet you are planning to use has power. Keep in mind some outlets are controlled on and off by a wall switch.

  • With the slot machine unplugged from the outlet and surge protector, open the slot machine main door. Remove the coin tray by lifting up and pulling out the tray. Simply pull it out and down to remove the tray.
  • The hopper is on the bottom floor of the machine and slides out on two base rails along two metal guides. Slide the hopper out slowly by grasping the handle with your left hand and supporting the hopper with your right hand. Do not use the black hopper bowl to pull the hopper out of the slot machine.
  • On the lower right corner of the slot machine you should see the black power cord coming into the machine. The power cord plugs into the Power Distribution Unit which is located on the back wall of the slot machine.
  • Verify the power cord is firmly plugged into place into the right side of the Power Distribution Unit.
  • Place the hopper back into the slot machine making sure it slides in easily and completely with the base rails on hopper guides on the bottom of the machine. The hopper plugs into a receptacle toward the back of the machine. It is designed to fit in easily without using excessive force.
  • The coin tray can be easily put back into place by ensuring the alignment pins on the coin tray match up to the top alignment holes on the bottom side of the machine. The tray should be pushed down into place. Make sure the tray is even when pushed into place. If the coin tray is not aligned and even, remove the coin tray, and repeat the procedure.
  • Verify the power cord is firmly plugged into a good surge protector. Plug the end of surge protector into the outlet you have verified is good, and make sure the on/off switch on the surge protector is turned on.
  • Now turn the power switch on the inside right of the slot machine to the on position and verify the slot machine is powered on by lights illuminating.

Jackpot Payout Reset

Fishing Slot Machine

When your slot machine just hit a 25,000 credit Jackpot it now needs to be reset to continue playing. Depending on the model slot machine you have and the amount of the payout will determine the best course of action.

If you have an IGT S+ Slot Machine and your win is under the maximum payout amount specified on the center glass of the machine, the hopper may run out of coins or tokens. This is normally displayed by Error Code 3300. In this case it usually a simple matter of taking the coins or tokens that have been paid out and putting them back in the hopper allowing it to fully pay out. However, if you won a large jackpot that is “hand pay out”, then follow the steps below.

  • First open the main slot machine door. Locate the Jackpot Key which is normally kept inside the slot machine in a plastic envelope on the side of the cash box. If you do not find it inside the machine, often times the Jackpot Key will be strapped with the main slot machine door key. It is a small key as pictured below.
  • Take the key in hand and locate the jackpot reset which is a keyhole located on the right side of the slot machine. It is normally about two-thirds up from the bottom of the machine.
  • Insert the Jackpot Reset Key into the keyhole. Turn the key only one quarter turn to the right. This will reset the machine, and once you close the main slot machine door, you will be ready to resume play.
  • Note that if you turn the Jackpot reset key multiple times you may place your slot machine into a test mode and will thus delay your ability to continue playing.

Some of the Error Codes you get on Slot Machine

Error Code 3300 (IGT S+ Machines)

Simply put Error Code 3300 is normally telling you your hopper is low on or completely out of coins or tokens.

Open the main slot machine door. Look into the hopper. If it is empty or has just a few coins or tokens, place about 500 coins or tokens back into the hopper. Close the main slot machine door. In a few moments you should hear the sound of the hopper’s motor turning and soon the remaining coin payout will begin.

Error Code 3100 (IGT S+ Machines)

Error Code 3100 (Extra Coin Out Tilt) normally signifies either a jammed/stuck coin or token in the coin-out chute on the hopper, or the hopper coin-out sensor has detected the hopper may have paid out an extra coin.

  • Open the main slot machine door. Remove the coin tray by lifting up and pulling out the tray. Simply pull it out and down to remove the tray.
  • The hopper is on the bottom floor of the machine and slides out on two base rails along two metal guides. Slide the hopper out slowly by grasping the handle with your left hand and supporting the hopper with your right hand. Do not use the black hopper bowl to pull the hopper out of the slot machine.
  • Inspect the hopper to determine if any coins/tokens appear to stuck or jammed in the hopper knife or the hopper coin-out channel.
  • If a coin appears to be stuck or jammed, empty the hopper of coins/tokens for easier access to clearing the jammed coin/token.
  • Once the stuck or jammed coin has been removed, place the hopper back into the slot machine making sure it slides in easily and completely with the base rails on hopper guides on the bottom of the machine. The hopper plugs into a receptacle toward the back of the machine. It is designed to fit in easily without using excessive force
  • Refill the hopper with the proper size coins or tokens. The coin tray can be easily put back into place by ensuring the alignment pins on the coin tray match up to the top alignment holes on the bottom side of the machine. The tray should be pushed down into place. Make sure the tray is even when pushed into place. If the coin tray is not aligned and even, remove the coin tray, and repeat the procedure.
  • Close the main slot machine door. The error code should be gone and the machine is ready to play.

Error Code 12 (IGT S+ Machines)

The 3.6 volt battery on the slot machine CPU Board normally lasts for years. However when an Error Code 12 is displayed, this is an indication the battery voltage has dropped below 2.9 volts and is now a low battery.

It is recommended to replace the battery as soon as possible. They can be purchased online from ebay, amazon or realslotmachinesforsale. When ordering a replacement battery, they will provide you with detailed instructions on how to change this battery which is located on the slot machine’s CPU Board.

In order to reset Error Code 12 temporarily, simply open and close the main slot machine door. It is important not to wait for a long time to replace the battery as data stored on the RAM may be lost. Replace the battery Asap.

Hopper is Full and Coins Go Down a Chute to Bottom of Machine

Slot machines that accept coins were designed this way because when used constantly on the casino floor, hoppers could quickly fill. There is a coin level probe on side of the hopper that looks like a brass screw sticking inward toward the hopper bowl. This probe detects when coins/tokens are at a selected level, and will cause the subsequent coins/tokens played to go down a chute to the bottom of the slot machine.

Provided your slot machine sets on a regular casino slot machine stand with holes in the top and the holes are aligned with the slot machine, those coins which bypassed the hopper will go down the chute, through the hole in the bottom of the machine, through the hole in the top of the stand, and into the open area in the stand cabinet. As casinos have done for years, place a small plastic tub in the slot machine stand cabinet to collect these excess coins.

Retrieving Currency from the Cash Box

Free 5 Reel Slot Machines

Though not all slot machines are equipped to accept currency in order to comply with certain laws but if your slot machine is equipped with a bill acceptor, bill transport and cash box, the bills in the cash box can easily be retrieved.

  • Open the slot machine main door. The cash box door is located just under the yellow chute for the bill acceptor. Ensure the cash box door is fully open.
  • On the right side of the cash box toward the top is a release level. Push release lever down and pull the cash box straight out toward you. If the cash box seems difficult or impossible to pull out, make sure you have pushed the release lever down.
  • Hold the cash box in both hands and turn it upside down. Notice on the bottom of the cash box is a door which has two small finger sized holes on one side. Normally the door is held closed by a small piece of electrical tape so the bottom cash box door doesn’t come open while removing it from the cash box chassis of the slot machine.
  • While holding the cash box with the bottom door up toward you, open the door and you will see where the bills are stored. The large spring expands as more and more bills are added to the cash box. Remove the bills by pulling them straight out.
  • Close the bottom door of the cash box and re-secure the door using the same small piece of electrical tape. Turn the cash box around to the original position when you removed it from the slot machine.
  • Align the flat top of the cash box with the flat surface at the top of the cash box chassis from which you removed it. Slide it firmly into place. Now close the cash box door and the main slot machine door and you are ready to use it for gaming.
