Beautiful and tricky strategy game

which for finding a solution, the brainpower calls pretty, but the way it should be. The degree of difficulty increases continually. This game gets to me a very clear recommendation to buy, especially for the currently offered here Price 0.79 €. It's always a pleasure to be able to continue to fiddle. Also runs without any problems, both on my Tab 3 and Blaupunkt Endeavour 785, each with Kitkat, as well as on my ancient 7 "Tab.
