Play this ALL the time! GREAT app! Fun, challenging and instructive. Technically excellent...no crashes or freezes at all (samsung4) and ads are non-intrusive. I really like the extra challenges (trophys)-that they're available but yet not required...and being able to offer and report questions. This adds an element of personal involvement that's nice. One of the only free apps good enough (and good enough value) that I'm considering purchasing pro edition for...and I NEVER pay for apps! GREAT job! Now...DON'T change stuff pls!
