It’s a simple game. You have to uncover pairs of identically colored Oxyd stones in a test of luck or memory. Move the black marble you control into a marked stone tile and it will reveal a color. Find another marked stone with the same color. If you reveal two identically colored stones in sequence, they will click open. Otherwise, the first stone will shut itself and you have to hunt for the corresponding color revealed in the second stone. To win the game, you just have to reveal all the colored pairs.

Simple as it may sound, the game is rendered more challenging and interesting by obstacles scattered across the paths to the Oxyd stones. Maps that extend beyond the screen leading to mysterious mazes and gates that change direction as you pass them are some of the enigmatic traps awaiting gamers. Tricky floors that make your black marble shrink and treacherous tiles that bounce, explode, poison, etc. are some other fun challenges to test gamers’ agility and luck.
