On

On is a term used in bingo that indicates a player has successfully matched numbers on their card with those called out.

In bingo, players aim to complete specific patterns on their cards by marking off numbers as they are drawn. When a player hears the term “on,” it means they have achieved a winning combination, such as a full line, a specific shape, or a full house, depending on the rules of the game being played. The term is often used to notify the host or other players that a player has a winning card.

On Example

For instance, if a player has the numbers 5, 10, and 15 marked on their card and the host calls out these numbers, the player would say they are “on” for that round, indicating they are close to winning.
