"We guarantee you that this is the best 15 puzzle game on the market!"
Well. No.
I installed it, tried it, and removed it immediately
1: every time I started a new puzzle it gave me a force close error
2: Once it finally started, it was impossible to slide multiple pieces at the same time, forcing me to do 3 taps for something I can do with one slide on a real 15 puzzle, and most other 15 puzzle apps on the market
3: whether I pick easy, medium or hard I get the original 4*4 puzzle and not the promised 3*3 and 5*5
Don't make promises you can't deliver.
