A gaming apparatus which comprises a slot machine capable of accepting
either paper currency, preprinted coupons, or cash out slips. The slot
machine also includes a printer that prints and dispenses cash out slips
which include a bar code representing a unique identification that
provides the amount of "winnings". The cash out slips can be scanned into
a separate currency dispenser at a Cashier's Station for receiving
currency, either from the dispenser or from an attendant. A central
processing unit (CPU) generates the unique codes for regulating the game
to be played, the wager limits of the game and the validity of the free
play coupons or the cash out tickets. The above gaming system avoids
having to use coins or tokens in the operation of slot machines.
