Magic Crystals is a game for one player. The goal of the game is to eliminate all the cubes, trying to score as many points as possible. The cubes are removed from the board if a group of cubes of the same color gets blown up. To select one of the two cube colors, you need to press either on the left or on the right side of the cube. The game ends when it is impossible to make another move or when the board is empty.
