About
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.
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.
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.
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.
Procedurally generated cases with selectable themes (mansion, cruise ship, brunch café, casino) and three difficulty sizes (7×7 easy, 9×9 medium, 11×11 hard).
Case timer with adjustable limits.
Manual deduction mode: cross out any cell yourself.
Full controller support: Navigate every menu and solve every case with a gamepad.
Furniture panel showing every object, orientation, and footprint in the current case.
Progress history and replay by seed for your favorite cases.
Interface in English and Spanish.

És el Murdoku pero en versió joc. Varis escenaris, vàries dificultats i les possibilitats son infinites! Hi la versió de descubrir el cadàver i acusar. L'altre es descubrir el culpable i acusar-lo amb l'arma que ho va fer. Pel preu al que està és una ganga! Si ho mires mes fredament, et surt mes a compte comprar el joc que no pas el llibre jkajajaja
Firstly I would like to apologize for the bad english you may encounter in this review, it is not my first language. It's an ok and cheap game. It has a good premise and for those who are starting to like puzzles I think it will be a banger. But I have played seven cases (and I know it doesn't sound like much, but the way you solve every level is still the same, nothing innovative needed), one easy and one medium to see what the game was about. Then, I played two classics on the hard mode and found it too easy and finally three on the investigation hard mode and solved it really quickly as well. I don't think it's that bad really, but to make your game have replayability you will need more then computer logic and the same written texts, like "Conrad was sitting on the chair", "Amir was alone in the bedroom" or "Beatrice was diagonally next to Jonah", because after the first few games it becomes automatic and not challenging, I just put the characters where they are supposed to be and by the time I reach the end of the puzzle it is either done or I have to make a simple sudoku trick, like a character is limited to two spaces on the same row, so there cannot be another character in that row. As for the Investigation mode, It's the same thing until I reach the end, where a good 14 year old who pays attention to his math lessons should figure that all the statements are factually correct just by looking at the board except for three, that talks about the murder weapons, and then, two of those statements are linked either for being impossible to be both correct at the same time (hence one is the murderer) or both must be correct at the same time (hence the third is the murderer). I am not a programmer, but I know a thing or two about computational thinking and I know it is hard to make a puzzle game that doesn't feel the same after a feel tries while trying to generate random levels, but this smells like AI generated the ideas for the game, when it should be confined to only write part of the code or to do nothing at all. I will wait for future uptades if it has any, but my recommendations to the developer is to try and innovate the solving methods needed in both modes, otherwise this won't stick with the puzzle enthusiasts, which should be most of your public, for long. As of now, I have not played the cooperative version since it needs a code to play online. The premise is good, having the clues divided between players, but I can't confirm (or deny) that the gameplay aspect is actually good. So, if you are new to puzzle games, I think you will like this, specially if it stays this cheap, otherwise, I wouldn't recommend it.
Me encantan los libros de Murdoku y los juegos estilo Cluedo, y CluDoku me ha recordado muchísimo al primero. Es cierto que el arte está hecho con IA, pero personalmente no me molesta. Me parece un juego muy entretenido que te hace pensar y resolver los casos, así que para mí es todo un acierto. Además, estaría genial que siguieran actualizándolo en el futuro, añadiendo nuevo contenido, más modos de juego y otras novedades.
I've only played a half hour so far but I'm extremely pleased with the game. Once you catch on to the logic of the puzzle it is quite the cozy mystery. Think in terms of the Sherlock games from Everett Games or Logic Town here on Steam. Clues that have to work together to make a clear picture. I found the investigation mode very engaging and the bonus of a spot the liar game on top is just icing on the cake. Looking forward to what gets added.
Pretty good an hour passed and I basically didn't notice lol. Once you get used to the keyboard shortcuts it flows perfectly F for furniture guide mostly hahaha and P for pass in cooperative mode Tab for clues (coop)
Muy adictivo el juego, cuando empiezas a jugar quieres una partida tras otra. Bueno para ejercitar la mente y los diseños pixelart y los escenarios estan muy bien diseñados. Muy recomendado
make it german text please. the game can be perfect for grandma.
Se lo he visto jugar a un streamer y he decidido probarlo. Pero se me da fatal resolver casos... aún así me gusta lo pulido que está! Voy a intentar jugar con algún colega en coop a ver si entre los dos podemos.
Ever since I was a little kid, I’ve always enjoyed games like this, so when I discovered this game I was thrilled! I personally think it’s pretty addicting, and I’m excited to see where the game goes with more updates.
Si te gustan los Murdokus (para los que no sepan qué son, mezcla de sudoku y cluedo) es genial, 2 modos de juego, 3 niveles de dificultad muy desafiantes sin llegar a ser frustrante, y cada caso se genera de manera aleatoria por lo que no se repiten. ¿¿Y encima por 3€?? Chollazo
