FlipMania is a free puzzle game developed by AppyHand, available on Android devices. The game consists of a board with two-sided chips, one side white and the other black, that need to be flipped to turn all chips black. But be careful, flipping a chip will also flip all the chips on the same line and the same column, adding an extra level of challenge.

With 7 board sizes and 130 free stages, the game offers progressive difficulty and addictive gameplay for both kids and adults. Players can earn coins to unlock 90 more stages, making the game even more interesting. The game also features clean graphics and animations, phone and tablet support, and a light and fast application. The game is supported by ads, but they can be removed for a small fee.

If you enjoy puzzle games like Sudoku, Reversi, and other brain games, FlipMania is definitely worth a try. With more stages added regularly, you'll never run out of challenges to keep your brain engaged.
