Flip is a simple puzzle program for the Psion Series 5. Nine tiles, black on one side and white on the other, are placed on a 3 x 3 grid and randomly flipped over. The aim is to flip them back to all black.
The tiles are initially all black, but can be shuffled - randomly flipped over - to expose their white underside. Your aim is to simply flip them back to all white. It sounds easy, but tap a tile and more than one flips over - and that makes it tricky. It's a bit like a two dimensional Rubik's Cube.
As you play, you'll discover certain moves that you can perform to flip certain tiles. What is the minimum number of moves required to solve the puzzle from any randomly generated state? You'll have to discover that for yourself.
