The 80-ball card is a 4x4 grid with no Free Space. The games and the rules are the same as for all variations of Bingo: the caller calls the numbers, the players cover the numbers on their card(s), and the winner is the first to complete a specific pattern. The 80-ball card used to have a kind of shutter that players used to cover numbers so it was sometimes called Shutterboard Bingo.
One interesting feature of the 80-ball card is that each column is a different color. The colors from left to right are red, yellow, blue, and silver.
