Your goal in this simple but addictive game is to rotate the outer ring of cells to catch the corresponding colored particles which move outwards from the center of the screen. For every particle you catch your energy bar gradually turns green, while missed particles cause it to gradually turn red. Keep it in the green to score points, but go too far into the red and it's game over. Fully max-out the energy bar with a chain of enough correctly matched particles to gain bonus points. Use LEFT and RIGHT ARROW KEYS to rotate the outer ring. Good luck!
