BlackFlip is a Polarium clone, an easy to play (but hard to finish) puzzle game perfectly suited for stylus play.

The rules of the game are really very simple : there are black and white tiles which need to be flipped so that each row is either all white or all black… Different lines can even have different colors. Yes, as simple as that !
But the twist is that you can only do a single path, which can’t overlap with itself. To draw that path, simple click on the puzzle, and move around. You can backtrack at anytime. To validate the path, simply click on the destination point and it’ll flip all the tiles !

The grey border around is a neutral zone : no flipping on it, and it’s not involved in the color check. So you can move on that one as if you were moving in and out of the puzzle. Doesn’t sound like much, but using the grey tiles effectively is the key to solving the hardest puzzles.
