Bingo number counter

[linbob65]

I am looking for a circuit to keep track of numbers called at out Legion bingo night. I have several single digit counters but no two digit counters. I can be contacted at ksrfisher@prodigy.net. Thank you

You could just do it the Low tech way
Just have a light and switch for each number.

What is the maximum number of, well, numbers that you will need to keep track of under each letter?
