The four corners in bingo are: the left, right, top, and bottom of the playing board. The first two are easy to remember- just remember the numbers 1-10. The other two corners can be a little trickier to remember.
The top corner is usually the number 12, and the bottom corner is usually the number 21. However, there are a few exceptions to this rule- for example, if the number at the top of the playing board is 2, then the bottom corner would be 18.
The fourth corner is a little more complicated to remember. It’s called “the Bonus Corner,” and it’s usually located in one of the corners farthest away from the center of the playing board. The Bonus Corner is where you find your bonus point if you get a Bingo! The Bonus Corner is also home to your bonus ball if you get a Bingo!.
