Why does it ask different questions of the two players?
It is a fun app; however, if you are seeking true competition, this game is a real flop. The app never asks the same question of the two players at he same time. It commonly occurs that one player gets 1+0=? while the other player gets something to the effect of 7x6=?. I just see the game as being more fun if I knew it was fair.
