About This Game

Million Cube is a 3D maze exploration game where you search for the one correct room among up to a million rooms.

Clues to the correct room are hidden in the numbers and characters on the doors, as well as in the scenery around you.

Supports multiplayer for up to 30 players.

Take your time and enjoy the scenery on your own, explore together with friends, or race to reach the goal first. Play at whatever pace suits you and your group.
