Combination Lock

Combination Lock Instructions

It's your first week of school...can you open your locker? Use your mouse to drag the dial in the desired direction. The dial will turn as long as the mouse is down. Longer drag gives you faster turn rate. You can also use the arrow keys, if you prefer. The combination is on the ratty piece of paper (unfold by clicking on it) - or you can try and do it from memory! Alternatively, you can use your X-ray vision (you are a super-hero, right?) to see what the wheels are doing and just turn them until the gaps line up at the top. Opening Instructions =============== 1. Spin the lock Clockwise a couple of full rotations to pick up the wheels, then turn to the first number. 2. Turn Counter-clockwise, past the second number once, then landing on it. 3. Turn Clockwise to the third number.
