A cold hilltop dome, one telescope, and a sky nobody was really watching. Sparse furniture makes the Observatory lean on rows, columns and neighbours — a scene where intersection technique carries you.
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: Dome, Library, Workshop, Archive, Terrace, Cellar, Office, Lounge, Garden.
17 features the testimonies point at: telescope, desk, bookshelf, clock, floor lamp, chest, potted plant, armchair, sofa, statue, window, crate, carpet, tree, flower bush, round table, bonsai — 13 block a square outright; 2 a suspect can sit on; 1 mounted on a wall edge, taking no square but anchoring "beside" claims; 1 flat underfoot, which a suspect can stand on.
The Old Observatory has hosted 11 days of shared cases, first on 31 July 2026 and most recently on 12 September 2026. 160 investigations have been opened on it, and 77% ended in the right accusation. The fastest anyone has closed a case here is 0:09.

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 Old Observatory's own, measured over the 11 days it has hosted.
