>No, it's just a simple game. If you have somebody near you, you can play. Two players say aloud numbers, I just gave a sample of the two players and possible numbers. Each number should be greater than the previous (from 1 to 10). E.g. I can say 5, and you can say 15 (or 6,7,8, etc). The first player, who says 100 (but you can play for 200 or any number, you define), will win.

Ok. I think I've got it.
The first player should win and he should say 1.
From that point forward to the numbers 11 from his starting number.
1,12,23,34,45,56,67,89. The key is that the one that says 89 first will win.

I believe if it was 200, you would need to start with 2 because you need to get to 101 first so that it duplicates the above solution. ( minus the 100 )
