Blackout is a term used in Bingo to describe when a player cannot make any more calls. This can happen for a variety of reasons, including when a player has reached their limit on calls or when the game is over.
When blacking out, a player is considered to have lost the game and must payout any winnings they had. Some casinos allow players to “revive” blacked out games by making additional calls, but this is not always possible or allowed.
In general, it is important for players to be aware of their blackout limit and to avoid going over it. If a player does black out, they should speak with their casino representative to see if there is any way to revive the game.
