About Unflip
Unflip is a browser puzzle game in which players drag across a square area of tiles, at least 2x2, to invert the colors inside it: white tiles turn black and black tiles turn white. The goal of each level is to make every tile white. Levels display a par value, described as the minimum number of moves needed to solve them, and the game includes undo and restart controls.
Beyond the main levels, the site offers challenge levels, daily and weekly levels, and puzzle books. A level editor accepts JSON imports and exports, and levels or solutions can be shared through a link. Solution statistics cover all solutions, the best result per player, and unique solutions. Past daily and weekly levels are accessed through a paid archive, and separate paid options for archive and full access are listed.
