Why is my game Sumdoit not a hit?
I love math and created a game called Sumdoit which I think is original and a great math puzzle. It uses very simple math with no answer greater than 20 so that players don't need a calculator. My son who is 10 can do all of the levels for the 2x2 and I play the 1st level of the 3 x 3 to get a bit of a workout nearly everyday. But it has not caught on. Can any of you give me a reason why?
