Black Tower Green Room Red Light Puzzle
CommunityCommunity-sourced: based on player reports and not yet verified by this site.
The Green Room Red Light puzzle in the Black Tower is a silent tile-matching challenge. One player reads a pattern through a one-way blackboard and flashes.
Head right from the Black Tower entrance and drop down near the two large green-grey pillars to find two rooms: one shows the tile pattern, the other is where you rebuild it, and voice chat is disabled. The player rebuilding places a tile in front of a one-way blackboard, and the player who can see the pattern reads the tile's position through it and answers with a red light. Agree on a light code before starting - a common setup uses the number of flashes to mean a slot number, so two flashes means the second position, while a burst of rapid flashes can mean the tile does not belong in the pattern at all. Place each tile, confirm it, then repeat until both sides match and the reward appears.
