A murder mystery played like a sudoku

A crime has been committed. Every suspect stood on a single row and a single column of the map, just like in a sudoku. All you have are their statements.

Cross-check the clues, rule out positions and place every suspect on the board. Only then will the truth come out: the one who was alone with the victim is the murderer.

Solved it? A completely different case is already waiting. And another one. Forever.

How it works

• Each suspect gives you one clue: the room they were in, the object they were next to, how many rows away from someone else…
• Tap to mark candidates, hold to place a suspect for real.
• Every case has exactly one solution. No guessing needed — just logic.
• Stuck? Hints point you to the deduction you're missing instead of giving the answer away.

Endless cases

Every case is generated from a code. Play a random one, type your own, or share the one you just solved so a friend gets exactly the same case.

Ten different settings — from a beach and a zoo to a museum, a mansion or a frontier town — and four difficulty levels, from a quick 6×6 board to a brutal 12×12.

Forensic Mode

The hardest way to play. Place suspects and weapons, find where the victim lay, then make your accusation: who did it, and with what? A perfect board isn't enough if you accuse the wrong person.

Compete online

• Ranked live matches, 1 vs 1 or 4 players, with Elo, leagues and seasons.
• Private rooms for 2–4 friends with a code.
• Watch your rivals' progress in real time while you race to solve the same case.

• A daily challenge: the same case for every player in the world.
• Daily and weekly missions, streaks and a world ranking.
• 100 achievements with Google Play Games.

Download

Recommended: get it on Google Play — free, with occasional ads and an optional tip to support development. It's the full version, with automatic updates.

Android APK (this page): the same game, version 1.6.26, for devices without Google Play. Please note that in the APK version:

• Online features don't work: Ranked, private rooms and the Community (Endless Maker publishing).

• If you later want the Google Play version, you'll need to uninstall the APK first, and local progress will be lost.

Offline play — all difficulties, Forensic Mode, the daily challenge and the Maker editor — works normally.
