TapSquaresFree is tile-based puzzle game for the iPhone and iPod touch. Tap a tile and it, along with up to four surrounding tiles, will flip. Keep flipping tiles until they're all the same color, and you win. Each tile can be one of three possible colors.
When a new game is begun, colors are randomly chosen for the tiles. To change the tile colors without starting a new game, shake the iPhone or iPod touch.
Using the Settings screen, players can choose how many tiles are shown, and thereby increase the difficulty. Optionally, a photo can be used instead of one of the tile colors.
