The rules of 80-Ball Bingo, start with the amount of uniquely numbered balls being limited to 80, with each ball representing a single number between 1 and 80. Throughout the game, a single ball will be drawn from the pool and its number will be read to all players. If the number is on your bingo card, you cross it off. Once you have filled your bingo card, to a certain amount – you win.
