This is a standard BINGO game that allows more than one player. This app allows you to draw the balls from the virtual bag where you can then mark the square on the Bingo card that matches the ball drawn. If you have more than one player, then it is necessary to have only one of these players drawing balls from the virtual bag on the device they are playing on. Other players can also mark the square that matches the ball drawn but only one player should be assigned to draw the balls from the virtual bag. If other players do not have an iPad or iPhone then they can use pre-printed Bingo cards that can come from cards that may be laying around, or, this app from which you can print Bingo cards. This app also keeps track of the balls drawn from the virtual bag and you can verify is someone claims to have won the game by comparing the squares marked on their cards with the list of balls drawn from this app. I feel this app can be very fun for events where you have several people who want to play BINGO.
