That is perhaps the most obvious title of any game ever, but in case you still can't guess what it is, it's a puzzle game, with tiles. Joking aside, the objective is to spin tiles around until there are no loose ends. The puzzles are randomly generated, and can have multiple solutions. If you want to change the difficulty, you can modify the grid size of the next puzzle in the options menu.
This game was very heavily inspired by an Android game called Infinity Loop.
