Cube Labyrinth Inside 3 - Regular
It is a 3-dimensional labyrinth totally in the dark. Release the ball, watch it go through the dark and try to get it out the other side by simply following the map engraved on the surface. But if that's too hard for you, you can always find a way to open the cube (no judgement, promise ! ). Difficult but not too long. Something to start familiarizing yourself with the concept of the labyrinth in space. It is still not recommended for beginners.
