You are trapped in a tunnel whose entrance and exit have disappeared.

As you make your way around a tunnel where the same space repeats, carefully observe the objects around you and how they are arranged.

Nothing changes on the first lap, so remember what your surroundings look like. After that, you must determine whether any object has disappeared or is out of place.

If something has changed, turn around. If everything is in its proper place, continue straight ahead. Each time you make the correct decision, another red light on the traffic signal lights up.

Spotting even the smallest changes is the key to escaping.
