How to Find Your Gear Combination

You will need three rocks.

Start with one rock. place it in one of the gears. Go back to the janitor and click the sun button to check the ceiling.

Your aim is to get the right hand side of the ceiling all the way open.

If your gear makes the left hand side open, or doesn't do anything, take it out and try another.

Once you find your first gear, leave the rock, and repeat the process with the second, and finally third rock. if a gear doesn't do anything, or makes the left hand side move, it's the wrong one.

If you jam the gears, it will reset the combo.

3 gears move the right side, 3 move the left, and 4 do nothing.

You will be able to click on the marks on the floor and the ceiling when you have the right side all the way open

Good luck!
