Cube Detectors

An empty Cube Detector back to back with the filled version.

Cube Detectors consist of a slot in which a block can be placed and a laser beam that runs across the slot. The detector will usually be activated when a block is placed in the slot and deactivated when it is removed but in some puzzles the opposite is true.


Most doors are opened by activating one or more cube detectors as part of a puzzle. The portion of the coloured circle in the center of the door that is lit up indicates the portion of cube detectors required to open it that are currently active.
