six to nine suspects. three to four acts. One house that hides more than it shows. Track everyone's movements, mark what doesn't add up, and name the killer before the timeline closes.
3–4 ACTS each — and the house resets between them. Everyone moves, and yesterday's story shifts under your feet.
Place each suspect where the evidence puts them, room by room. Doors, windows and timings all count — the floor plan is your witness.
Tag cells with notes and crosses. When two statements can't both be true, the contradiction strip lights up — you're close.
Name who did it, where, and when. Get it right and the case closes. Get it wrong, and the house keeps its secret a little longer.
32 hand-built cases, each with its own house, its own cast, and exactly one solution. Pick one to open the file — the rest live in the game.
Each case casts its own characters — six to nine of them — through three to four acts. They move. They contradict each other. One of them is lying about all of it.
