In our facility, we tried all that Dollar Store stuff, also cracker, candy bars, etc. They hated it. So I went for nickel a card, they could play as many card as they had money for, per game. If more than one person called Bingo we would divide the pot with how many won. They like that money a whole lot better. An sometimes the pots get to be quite alot of nickels in. Then on the cover all, I played for ten cent a card. We play one hour, 4 times a week. I have a great turn out.
