When playing bingo, players must match the numbers called out to the numbers on their cards. If a player has only one number left to complete a winning pattern, they are said to be “1TG,” which puts them in a high-tension spot. They are very close to winning but must wait for that one last number to be called.
1TG Example
For example, if a player has a bingo card and the number 32 is the only one left to mark, they are considered 1TG, hoping the number 32 will be called next.
