A quick and fun way to sharpen your mind and exercise your brain by doing math in your head, like an everyday genius!
Doing numbers in your head will never be the same as you complete two continuously challenging quests with up to 50 levels each. Start with a number then see what to do with it while keeping track of the answer. Simple really. Ready? 5.. plus.. 300.. minus.. 25.. keep going!.. times.. 2. Every level is different, every time.
You can also set up custom games to control length, speed, operators and numbers while you challenge your friends or help beginners fall in love with doing quick calculations with just their minds.
