Tuxmath is an educational game. It’s almost the same like Tetris, only you don’t have to play with blocks.What you have to do is only answer every question that falls the top. I think it’s a good game to sharp your brain to think fast. After you install the application, you will get a new tuxmath menu under Applications > Games.
