Four Corners is one of the most popular bingo games in the United States. The object of the game is to cover a complete row or column with your ball(s) before your opponents can do the same.
There are several ways to play Four Corners, including traditional bingo, where all players get one ball each, and Russian bingo, where each player gets two balls. In either game, players can choose to go for a single number or try to cover as many numbers as possible.
There is no official rule about whether Four Corners counts as a single game or multiple games, but most experts believe it should be counted as a single game. This is because Four Corners is similar to other traditional bingo games, such as Rush Hour and Double Bonus, where players are trying to complete a specific pattern.
