Customer Reviews

Nice challenge

Fun and challenging without being frustrating. A little easy to start, but by the 100th level, it starts to get interesting.

Lost hours

Really addictive platform that made me lose time and stay up waaaaaay too late. Save some for Dad now

Another win

TM Soft does it again with an addicting and challenging game that keeps me entertained in waiting rooms, passenger seats of cars, and at work.
