You need to use both marbles in the next part.

Bring both marbles as shown below, then turn the mechanism clockwise. The last puzzle will be unlocked.

There is an element with an arrow sign.

Remove the key.

Pay attention to the arrows showing rotation.

The outer arrows show how to rotate the box, the inner arrows show the rotation of the central part.

Here’s the correct position of all gears. After you set them, the marble can go through this side and come out on the next puzzle. Shake the box if the marble gets stuck in the tunnel.

Put the box onto a perfectly flat horizontal surface (the side with 6 marbles is on top). Hold the central part and spin the box rapidly clockwise – all marbles should roll to the outer end. Then rotate the central part anti-clockwise and take it out. Watch the video to see how to spin and

Turn the disc with 2 dots all the way anti-clockwise and lead the marble through the tunnel.

Bring the marble to the smaller hollow of the 2nd disc and lead it through another tunnel to the 3rd disc.

As the marble came out of the last tunnel, turn the 3rd disc and bring the marble into the small hollow. Then turn the disc anti-clockwise – the marble can now go to the next side of the Labyrinth.

Find a special arrow.
