Types of Gaming Machines

• Video Slot Machines• Characterized by:

• CRTs or LCD monitors• Newest ones have the CRT and top glass replacedby one large LCD display or by two LCD displays

NOTE: CRT – Cathode Ray Tube & LCD – LiquidCrystal Display

• Simulated Spinning Reels on the monitor• 3 -7 reels

• Multiple Games available on the machine

• Reel Type Variations• Found on machines using Stepper motors or CRTs/LCDs

• Multiplier• One Credit/Coin played - Pays 1 X pay-table• Two Credits/Coins played - Pays 2 X pay-table• N Credits/Coins played - Pays N X pay-table

• Bonus Multiplier


• Bonus Multiplier• This machine operates the same as the multiplier except that it

offers a bonus when you play maximum coins and hit the jackpot

• Multiple Payline• These machines have more than one line of play.

• Each coin activates a particular line.• If you hit a winner on a line that is not activated, you will not

receive anything.• The older machines used to have three lines but the newer video

slots can have many lines.


• Buy-a-Pay• These are often misunderstood• Each coin activates a different pay out. You need the maximum

coins to receive the largest jackpot.• Example –“Sizzlin 7’s” machines have cherries, bars and sevens.


• Example –“Sizzlin 7’s” machines have cherries, bars and sevens.• If you play one coin you can collect only on the cherries.• f you play two coins you can collect on cherries and bars.• You need three coins in to collect on the 7’s.

NOTE: If you hit the jackpot with one coin in YOU WILL NOTWIN ANYTHING!!!

• Progressive Slots• The progressive slots take a certain percentage of the money played

and add it to a pool for the top jackpot.


• Progressive Slots• “Megabucks” or “Quarter Mania” are examples of machines from

several casinos linked together to offer a life changing jackpot.• Some casinos have machines linked together within their own

casino to offer mini-progressive jackpots.

• Nudge machines• Have a light mounted on them that comes on occasionally.

• If on the player may move (nudge) a wheel forward or backwardone location.

• Sometimes this is all that is required for a losing hand tobecome a winner.

doubling (or losing) your winnings
