The object of the game is to find a
hidden chalice in the maze, which
is a cube of 3 to 8 squares: up to
512 locations. You can move forward,
turn left, right, around, up and down.
Using these in combination can get you standing on your head, so take care. The only indications of your
whereabouts is the distance and level.
The rest is up to your spatial memory.
