Math Sprinter Hack 1.0 + Redeem Codes

Don't be average...!

Simple (at the beginning) math workouts. You reach the next level if you are faster than the average - easy, isn't?

Perfect exercises if you have a couple of minutes left (bus, before/during a meeting, at the coffee machine,...) and would like to do some workout for your brain.

Attention: For 'experts' only - otherwise you might get a headache!
