Download Cluedoku for iPhone and Android
On iPhone and iPad, Cluedoku is on the App Store. On Android, it is on Google Play. Both apps are free to download, carry the same cases and the same modes, and are built around the same daily habit: one new case every day, a streak to protect, and trophies to collect along the way.
The apps also do the one thing a browser tab cannot: they work offline. Cases are stored on your phone and solve without a connection, so a subway tunnel or a flight is no reason to lose a streak. Multiplayer and the leagues still need a connection, the solving itself does not.
No Download? Play Free in the Browser
The whole Cluedoku game also runs at cluedoku.app, with no install and no signup needed to open today's case. It is genuinely free to play, not a demo: the daily case and the story campaign are both there, with no energy timers and no wait to start the next one. If you later grab the app, an optional account carries your streak, trophies and progress from the browser to your phone and back.
What Cluedoku Actually Is
Cluedoku is a detective sudoku: a murder mystery you solve on a grid. Every case gives you a floor plan divided into rooms, a cast of suspects, a victim, and witness statements as clues, and every clue is true. You place the suspects on the board sudoku-style, no two sharing a row or a column, and cross off impossible cells until only one arrangement is left. Whoever ends up alone in a room with the victim is the killer.
Every case is verified to have exactly one solution reachable by pure deduction, so you never have to guess. New to the genre? The how to play guide walks through every rule and clue type with examples.
If you arrived here from the murdoku books or from a murdoku video, that is the same genre and you will be at home immediately: same one-solution promise, same witness-statement clues, built for a phone instead of a page. There is more on how the two line up on our murdoku online page.
What's in the Game
- A free daily case, the same for everyone, with a streak to keep alive. More on the rhythm on the daily case page.

- Ranked duels: race another detective to crack the same case first.

- Weekly leagues that climb from Wood all the way to Diamond.
- Dozens of trophies to unlock as you solve.
- Offline play in the iPhone and Android apps.
- The whole game playable in 19 languages, cases and clues and hints included, not just the menus.
