Where The Calls Come From

As you might have guessed the most popular bingo call for the number 20 bingo ball is Key Of The Door or Key To The Door. This nickname is given because at 21 you are supposed to be given the key to the door and are now able to do what ever you want and come and go as you please.

Just My Age, and If Only I Was are used as a joke because older people tend to play bingo and they wish they were 21.

Whenever a member of the Royal Family has a birthday there is a 21 gun salute which is why you’ll sometimes hear the bingo call for 21 as Royal Salute.
