Cash cube, money machine cubes and money machines are some of the most effective business promotional products because they allow everyone who plays, a chance to win money while providing great fun for observers. These money machines are used by Schools, casinos, auto dealerships, banks, radio stations, trade shows, business grand openings, fund raisers, employee promotions, the rental industry and more to promote their business or ideas. These cash cubes can be used to blow cash, paper money, vouchers, certificates or any paper product. Winnings are controlled by time in the money machine, denomination of cash or value of certificates, and amount of cash or certificates in the machine. Usually about 200 bills are inserted into the cash cube made up of mostly one dollar value bills or certificates. Larger bills can be mixed within the machine to increase perceived value and excitement of playing the game. Rules do not allow players to pick up bills below their knees or to trap money with their body against the machine wall. They may catch bills only in the air. All contestants must wear safety glasses and exit when directed to. Player handicaps such as wearing obscuring glasses, using only one hand or having to stuff winnings in a pouch or pocket can extend the amount of time players can be in the machine.
