The 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! Draw a line in the given grids and make sure the line doesn't intersect with itself. After this only operation, all the grids on the line flip - the original white grids become black, while the original black ones become white. The goal of the game is to make all the grids on every horizontal line in the same color - either black or white. If you are not sure how to play, check the instructions in the game, a video is included.
