A shore, an interior, and no boat that anyone will admit to hearing. The Mystery Island mixes open ground with tight shelter rooms — flexible casework that tests the whole technique ladder.
One of Kludoku's 23 crime scenes. The rules never change — place every suspect from testimony alone, and whoever ends up beside the victim did it. What changes is the map, and the map is what decides whether a case falls open or fights back.
9 rooms: Beach, Lagoon, Jungle, Camp, Cliffs, Cave, Wreck, Lookout, Dock.
10 features the testimonies point at: palm tree, campfire, tent, boulder, crocodile, shrub, crate, chest, floor lamp, bench — 10 block a square outright.
The Mystery Island has hosted 11 days of shared cases, first on 3 August 2026 and most recently on 30 August 2026. 82 investigations have been opened on it, and 73% ended in the right accusation. The fastest anyone has closed a case here is 0:16.

Board is columns × suspects, and rooms is how many regions that grid is cut into — both set by the difficulty, not by the scene. Testimonies is how many statements it took before exactly one arrangement survived, assumptions the assume-and-test rounds needed once plain elimination ran dry, and liar the share of cases hiding an accomplice whose every word is false. Those three are The Mystery Island's own, measured over the 11 days it has hosted.
