The machine works much like the Mills BONUS slot machines. Spell out the word BONUS by landing on the letter symbols and when the word is completed, a silver dollar is dispensed on the nickel side, or a token good for 5 silver dollars is dispensed on the quarter side.The machine was in a storage locker for a number of years and is NOT working at this time. It looks like it was restored before being put away and looks complete except for tokens and the key for the token dispensers. I have not attempted to repair it. I did plug it in and had the reels spinning, but that was it. If you spend a little time to get this up and running, it will be a fantastic machine!
