Default [game][2.3+] Math*Tiles=Run (a crazy math race)

All,

I have just release a new app called "Math*Tiles=Run" - as one may guess its a math "race" where you are presented with a set of simple arithmetic equations to solve. But the goal is not only accuracy but speed as well. Think of it as an educational version of "white tiles" kind of game
  • Can you handle one question per second for a minute?
  • What is your time on a 20 questions sprint?
  • How many questions you can handle during a "3 minutes math marathon".

Please have a look and let me know your comments on the gameplay. Thanks in advance.
