Fun, fast game if you like math challenges and competition with yourself and others. Between this and wordament, I will happily wait in a waiting room.
Great Game. The short break between rounds is nice and I love how they negative numbers as well as division and mutiplication. Great for keeping your mind sharp.
Have been using iPhone for 2 years now and couldn't find a decent + interesting game that will sharpen your knowledge and skills. But the WP7 usage for 1 month landed me with this fun/reflexive game. Kudos to the developers.
