You Only Get One Chance

in the letter game, the words get longer, but you never need to look at more than the first two letters, since they're all almost always different. The other modes were just standard math blaster game modes.

Upon ending a round, the score counter should stop too.

Challenging, I really like the letter puzzle.

This is a bit like brain training. I liked the letter one the most. The number ones are hard unless you have a calculated.
