Do Slot Machines Take Coins

If you’re a total beginner and have never played slots before, or have played once or twice but are still confused by how it all works, this guide on how to play slot machines for beginners has been written just for you.

In most of major casinos on the strip, the slot machines no longer take coins or tokens. Nowadays, you put in cash (bills). You can play, and if you decide to cash out, you are given a receipt. For example, if it’s a two-coin machine and the jackpot payout is 500 coins when you bet one coin, but it pays you 1,200 coins when you bet two coins, then that machine is paying you a 200-coin bonus for playing the maximum number of coins and you may want to bet the maximum two coins to take advantage of that bonus. There are still a handful of casinos who offer vintage coin-operated video poker or slot machines. The vast majority of casino machine games have been modernized with the TITO (Ticket In Ticket Out) system. Coin-operated games are now so vintage that The D no longer offers them in their 2nd-floor vintage casino.

Do Slot Machines Still Take Coins

Even if you’ve never played slots before, you’ll understand the A-Z of how to plays to machines properly by the time you’ve finished reading.

How to Play Slot Machines for Beginners

The first thing you need to understand about how to play slot machines is the different elements of the game. These are:

Reels – Slot reels run horizontally across the game screen and are the ‘slots’ in which symbols spin. Games can be 3-reel, 5-reel, or even 6-reel. If you look at the screenshot above, this game has five reels.

Rows – Each slot has a number of rows which run vertically. Most slots have three rows, but some have more. In the game screenshot above, you’ll see three reels.

Paylines – Paylines are the patterns which can make winning combinations. For example, if a slot has 25 paylines and you play the game with all of them activated, you’ll have 25 different ways to win. In the screenshot above, you’ll see that this game has 25 paylines.

Symbols – The symbols are the icons which spin on the reels. Each symbol has a different value and how much you win for making combinations will be determined by the value of the symbols.

Once you understand the basics of slot machines, it’s time to take a look at how to play casino slot machines step-by-step.

How to Play Slots for Beginners – A Step by Step Guide

For the sake of keeping this guide on how to play slot machines simple, we’re going to pretend you’re playing the game you see in the screenshot above. It’s called Mega Fortune and is a great game for beginners since its simple and has several huge progressive jackpots.

Below is a step-by-step procedure showing how you how to play slot machines, specifically Mega Fortune in this example. It works basically the same way for all slot machines, although there may be some variations depending on the software developer.

So, to place a bet on Mega Fortune slot, you would:

Step 1

Make a deposit. Unless you’re playing free slots or have a no deposit free spins bonus, you’ll need to deposit funds before you can play. You can usually do this in the ‘account’ or ‘banking’ section of your casino.

Step 2

Determine the number of paylines you want to play. In this game, the number is fixed at 25, but you can view each payline by clicking the numbers at either side of the game screen. In some other games, you can determine how many lines you want to play per spin.

Step 3

Decide your coin value. In Mega Fortune, you can set your coin value between £0.01 and £0.50. Remember, you’re betting one coin per payline, so if you were to set your coin value at £0.01, you would be betting £0.25 per spin.

Step 4

Set your bet level. This isn’t a feature of all video slots, but it is for this one. You can increase your level from between one and four. The higher you go, the bigger your bet size. For example, if you bet with a coin value of £0.01 at level one your bet size would be £0.25. If you bet with the same coin value at level four, your bet size would be 4x greater or £1.

Step 5

Hit the spin button. This is where the fun begins. You’ll see the symbols spinning on the reels, and if you land a winning combination, you’ll receive a payout. The payout size depends on how many symbols you’ve landed, your bet size, and the value of the symbols.

Playing slot machines is as simple as that. It’s not rocket science, and you’ll master it in a few spins. If it all seems foreign to you, we suggest getting familiar with the process by playing some of our free slots until you feel comfortable.

Slot Machine Lines Explained

Paylines often confuse beginner slots players the most, and no How to Play Slot Machines for Beginners guide would be complete without explaining them further.

Basically, paylines are patterns, and if you match symbols across them, you win payouts. On most slots, payline one will be straight across the middle row, as in the screenshot below.

However, paylines aren’t always so simple. They can go in all sorts of directions. Just take a look at payline 10 on Mega Fortune in the screenshot below.

Paylines can go in many directions, but don’t worry about them too much. All video slots will calculate your wins for you automatically. You don’t have to look out for these patterns at all. If you land symbols on an active payline, the game will let you know. It will also calculate and display exactly how much you have won.

Understanding How to Play Slot Machines – Game Symbols

The basic mechanics and structure of a slot machine is one thing, the paylines are another, and the different symbols are yet another thing you’ll need to understand.

Most slots have the following symbols, although again, it can vary from game to game.

Common Symbols – These are the common slot machine symbols which make up winning combinations. They don’t hold any special function, and landing combinations of them pays out wins in accordance with the paytable.

High-Value Symbols – These are common symbols, but they pay the most. If you look at the screenshot above, the white limo is the highest value common symbol. Keep in mind that this might not be the highest value symbol once special symbols are considered, as is the case in Mega Fortune.

Scatter Symbols – Scatter symbols can trigger bonus rounds and also often pay when you land three or more of them on the reels.

Wild Symbols – Wild symbols can substitute for other symbols. For example, if you had four matching symbols on reels one, two, four, and five, and a wild landed in the middle, you’d have a five symbol combination. Wild symbols can sometimes stick, move, or expand on the reels.

Bonus Symbols – These are special symbols which trigger bonus rounds when the land is certain patterns or combinations. For example, in this game the bonus symbol is a wheel, which leads to a special bonus round.

Understanding Slot Machine Bonus Rounds

Modern video slots are a far cry from the simple fruit machines you might find in pubs and bars across the world. Even in world-class casinos in Las Vegas and elsewhere, few slots have bonus rounds which can match online slots.

Bonus rounds can confuse some new players, so we thought we’d describe them here so that this How to Play Slot Machines for Beginners piece is complete. Bonus rounds contain lots of slot machine secrets.

First, you should note that you can always find out what bonus rounds and special features a game has by viewing the paytable.

As the above screenshot shows, you can see which slot machine bonus games the game has built into it. You can also see how to trigger each one. One of the best things to do when you’re learning how to play slot machines is to study game paytables.

Some of the best slot machine bonus rounds are:

Free Spins – You’ll get a predetermined number of free spins. Sometimes you’ll be given a multiplier which boosts your wins, for example by 3x or more.

Bonus Wheels – The name explains it all, really. A wheel will spin, and you’ll win cash prizes, free spins, and access to other special rounds and features.

Picking Rounds – You’ll see a number of items on the screen and will need to pick some of them to win cash payouts. Sometimes progressive jackpots are built into picking rounds.

Secrets to Winning on Slot Machines

If we knew how to play slot machines and win every time every time, we’d be too busy sunning ourselves in the Bahamas to write this guide for you.

  1. Manage your bankroll effectively. This is probably the number one trick to winning slots more often. Don’t get carried away and don’t chase losses. Decide how much you’re willing to lose beforehand, and only increase the size of your bets when you’re playing with ‘house money.’
  2. Check how volatile the game is. Some games go for long dry spells and then pay big wins, or lots of big wins, suddenly. These are high volatility slots. Some pay smaller amounts more frequently. These are low volatility slots. Your strategy on how to play slot machines should be determined in part by the game’s volatility.
  3. Investigate the bonus rounds. If one free spins round has a 2x multiplier while another has an 8x multiplier, it makes sense to play the one with the bigger potential. Take your time to look at the paytables and see what’s in store.
  4. Understand that you can’t cheat. There are lots of articles online titled ‘How to cheat at slots’ and other variants of this. They’re all BS. Save yourself the time and money wasted with these systems. Random number generators determine game outcomes. There are no patterns, and slot cheat codes don’t work. Learn how to play slot machine effectively and hope for luck to show up.
  5. Pick high RTP slots. Each slot is programmed to pay a certain percentage of all bets back to players. You’re better off playing a slot with a 98% RTP than one which pays 92%.

Some casinos choose to give new players free spins on slots for making a deposit. For example, you might get 10 free spins for making a £10 deposit.

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.
  • 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

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

Coins

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.

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

Slot Coin In

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.

Do Slot Machines Take Coins

  • 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.
