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, find the weapon used, 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.
Two case variants
Fast — The victim shares a room with a suspect. Find the weapon used, find the room, discover the killer and the victim. Classic Sudoku logic featuring mechanics inspired by the famous Zebra Puzzle (Einstein's Riddle).
Evidence — 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.
