SusDoku

SusDoku combines sudoku-style logic with murder mystery deduction. You place suspects in rooms using clues, identify the weapon and killer, and solve each case before you run out of chances. Cases generate a grid of rooms and a group of suspects; clues restrict where each suspect can go, and you interrogate suspects before making an accusation. The game is designed around deduction rather than guessing.

Case variants

Each case uses one of two formats:

• Fast: The victim shares a room with a suspect. Find the weapon, the room, the killer and the victim using classic sudoku logic and mechanics inspired by the Zebra Puzzle, also known as Einstein's Riddle.
• Evidence: Several weapons are hidden across the map. Investigate furniture and locked cells to uncover them; you can solve the case only after finding all the weapons and interrogating the suspects.

Play modes

Play alone at your own pace without time pressure, or set a timer for an added challenge. Local pass-and-play supports 2–4 detectives taking turns on one device. Each player keeps clues private in a personal dossier and shares deductions with the team; placements begin as color-coded proposals, and another detective must confirm each mark. Online co-op lets you play with friends through Steam lobbies by sharing a room code.

Case options

Cases are procedurally generated, with five selectable themes: space station, mansion, cruise ship, brunch café and casino. Choose among three grid sizes and difficulty levels: 7×7 easy, 9×9 medium and 11×11 hard. You can adjust case timer limits, cross out cells in manual deduction mode, and consult a furniture panel that shows each object's appearance, orientation and footprint in the current case. The game also keeps a progress history and lets you replay cases by seed.
