Goal of Blackflip is to flip the black and white tiles so that each row is the same color! All levels (more than 10,000!!!) are made and submitted by fellow Blackflip players, and are solvable in at least one way. Using the level creator, you can create a puzzle as large as 13 squares wide or high. But before you can submit any near-impossible hoo-haw, just remember that for a puzzle to be listed on the site, you have to prove it's beatable by being the first to solve it! As a bonus, you can link to your own puzzles on your website with the provided tags. Your game process will be saved automatically. If you think the game is too hard, try ordering the puzzles by difficulty using the the pulldown menu in the upper right corner. Start with some easy ones before playing the really hard ones created by pro players. Click the preview of puzzles with your right mousebutton for extended options! Blackflip is tribute to Polarium for the Nintendo DS made by Mitchell Corporation. So thank them for the original game principle!
