Your object is to match gems vertically or horizontally by flipping them. You have to match at least 3 gems to gain score, otherwise the flip will be reversed. There are different types of gems such as the stoneblocks that can't be moved and drills that destroy the blocks when matched. In attack mode you get one minute to gain as much score as possible. While playing survival, you have to keep a timer up by gaining score. Classic mode consists of 8 levels, play it through as quick as possible. In all modes, the game gets harder the longer you play. Your score will be submitted to a local and a online highscore table so you can compare your flippin' skill with others.
