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.

For more details on how the game works, check out the video !

The games main feature is it's incredibly hi number of puzzles : more than 6000 !!! These range from very easy (0 stars, solvable in a few seconds) to very hard (5 stars, only solvable in a few minutes and by advanced players)...

This early release is pretty crappy, misses a few graphics, and doesn't actually have more features than that. But all the puzzles are available/solvable, and your progress is saved.

If you like puzzle games, this is a must-have ! If you don't like puzzle games... Well... Just give it a try, it's a matter of seconds before you learn how it works and see the potential of the beast. Just don't play directly on the harder puzzles...

TODO-list for the next versions:
- In-game level creator.
- Level generator with difficulty settings (not as fun as real levels, and... well, just finish the 6000 levels first...).
- Etc...

ALL the credit for the game idea goes to Mitchell Corp. for creating the original Polarium game (for Nintendo DS and Gameboy Advance). If you like this game, considering buying one of those versions, the author definitely deserves the money !

Blackflip Pocket PC is a port from the flash version by [F]laboratorium.org. All the credit for the graphics and the levels go to them and all the users who contributed to making/sharing all these puzzles. The game will be updated regularly to have up-to-date versions with the latest levels !

Have fun !
