It is a simple game for brain jogging for young and old. Older people should exercise their brains daily. The object of the game is to remove all of the stones from the screen before the time runs out. Two stones are removed at a time, and must be of the same color. The path used to connect the stones can only be up, down, left or right (no moving diagonally). As well, you can't go through other stones to get to the one you are looking for. The path between two stones can turn maximum two times. You can change this in the premium edition. In the nivel Kids for example there are 4 turns allowed. If you click on the wrong stone, you can click on the stone again to deselect. After completing a level, you will be rewarded with a bonus point for every second left on the clock, From level to level the time to complete will be reduced and bonus points will be converted to extra time. In the basic version you get every 5th level an extra bonus time and a reduction of errors. The app records a high score which can be resetted in the setup.
