Whiteout

Whiteout is a challenging puzzle game based on strategically flipping black and white tiles.

The objective of the game is to turn a mix of white and black tiles to all white tiles in the fewest moves possible. When you tap a square, it will flip the color of the tile you tap as well as the tiles directly above, below, to the left of and to the right of it.

Levels are organized into 8 groups with each group number corresponding to the minimum number of moves required to reach a whiteout (for example, a level with difficulty III will require a minimum of 3 moves to reach a whiteout.) Each time you reach a whiteout, the next level will be unlocked.

If you complete a level in the minimum possible moves, you will be awarded a gold medal as well as an additional hint (you start the game with 10 hints.) If you waste only 2 moves, you are awarded a silver medal; and if you waste only 4 moves, you are awarded a bronze medal. If you waste more than 4 moves, you may advance to the next level but you are not awarded a medal.
