Use the stone to remove spider web that was woven in one of the corners of brick area.
You can control the stone by rotating a big gear.

You have to take control over gravity, speed, friction and inertia to complete a level successfully.
Rotate the gear clockwise and/or counterclockwise and lead the stone to the web.
Beware of spikes and lasers. They will not let the stone roll easy.

There are only two buttons in the game, so control is very simple.

Good luck!
