Green Tower Lightbulb Locked Room Puzzle
CommunityCommunity-sourced: based on player reports and not yet verified by this site.
The Lightbulb Locked Room puzzle north of the Green Tower locks two players in facing rooms with missing screens, linked by a red signal light and a tannoy.
North of the Green Tower at map coordinates 3825, 1930 is a chartreuse building with two rooms. The left room holds nine puzzle pieces and a display board missing its first and second screens; the right room has the same nine pieces in the same order with the third and fourth screens missing. Once locked in, the left room communicates with a red light - pressing it a number of times signals a number, such as two presses for piece two - while the right room can talk over a tannoy to the left room. The players tell each other which of the nine pieces the other is missing, place them in the slots, then press the red button under the black screen to check the solve; confetti confirms it.
