I tried this for mobile and liked it to start with for a few levels, then it got progressively harder and I had no hints and couldn't finish it. I am unsure if you had to spend real money to get hints. Didn't enjoy it due to difficulty and lack of hints. There is a PC version of it I tried today, which I tried which also difficult. You get a hammer, but this only is charged up the more you play, so not very useful. You do get hints which tell you moves, but you have to wait (not sure what "show moves" is compared to "Show hints" as the game isn't move based that I noticed?? I didn't enjoy this.. not for me
