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.
