A murder has been committed. Can you solve it?

CluDoku blends the satisfying logic of sudoku with classic murder mystery deduction. A victim has been found — your job is to place suspects into rooms using clues, eliminate the impossible, and name the killer before you run out of chances.

How it works

Each case gives you a grid of rooms and a set of suspects. Clues constrain where each suspect can be. Place them correctly, find the victim's room, and make your accusation. Every deduction is yours: no guessing, pure logic.

Two case variants

• Classic — The victim shares a room with one suspect. Find the room, name the killer.

• Evidence — Three weapons are hidden on the map. Investigate furniture and blocked cells to uncover them. Only when all weapons are found can you resolve the case and the combined clues reveal the true murder weapon before you make the accusation.

Play your way

• Single-player — Solve cases at your own pace with no time pressure (or set a timer for a real challenge).

• Local co-op (pass & play) — 2–4 detectives take turns on one device. Each detective keeps their clues private in a personal dossier, then shares deductions with the team. Placements start as color-coded proposals; a second detective must confirm each mark.

• Online co-op — Play with friends anywhere via Steam lobbies. Just share the room code and solve together.
