About This Game

A murder has been committed. Can you solve it?

SusDoku 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 procedurally generates a grid of rooms and a group of suspects. Clues restrict where everyone can be. Place them correctly, locate the weapons, interrogate the suspects, and make your accusation. Every deduction is yours—no guessing, just pure logic.

The case:

• Evidence — Inspired by the famous Zebra Puzzle (Einstein's Riddle), one or more suspects discover the body, while several weapons are hidden across the map. Investigate the furniture and locked cells to uncover them. Only after finding all the weapons and interrogating the suspects will you be able to solve the case.

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.

Features
