The Portable Gamer writes: "The object of the game is to match the colored and patterned pieces with each other, removing them from the board. The grid is laid out in columns and rows, and each pice has two sides, hence the flip part of bitFLIP. Using the touch screen to directly manipulate the "handcuff" widget (officially called the switch by the developers) into position over two game pieces, players can then flip the pices over, showing the opposite side. This leads to all sorts of interesting and strategic gameplay. It's amazing what a small addition to a standard match-three game will do. We saw it with Dapple's color mixing metaphor, and bitFlip simplifies and refines the concept even more with the dual-sided pieces."
