Play by matching colored marbles to clear the game board. As marbles are cleared, the board collapses, often leaving one or two orphaned marbles at the end of the game. Careful planning will yield an empty board. Higher levels include more marble colors, blocking walls, shifting boards, cloaked "invisible" marbles, and other twists to challenge even the best players.
Corregon includes 20 levels, detailed scoring statistics, and provides an online high scores system to compete against others around the world.
