I still believe that quell is the daddy of the sliding puzzles, but this game has its charm too. The levels are very small in size, which makes them perfect fit for smartphone screens and big fingers. If you want some serious challenges, play quell or orbox c, but if you have just a spare minute and want to solve some nontrivial puzzle in that time, this game is what you need. This game starts with very simple levels, and I almost uninstalled the game because of it. But keep on and it'll be more interestin
