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.

Feels like AI generated slop, with bad gameplay and puzzles. Sure, it's cheap, but it's no good, don't waste your time.
I love sudoku so this was very intriguing and I did really like it once I got the hang of it! Plus it runs perfectly on steam deck (aside from text being slightly hard to read (which isn't really relevant once you've read the directions) and some of the furniture being hard to distinguish on the hard maps, which have larger grids and are thus scaled down from the easier difficulties.) However, in less than 2 hours of playing I've already gotten the exact same "generated" mansion map setup 3 times and another one twice. If there was more variety I would keep playing and enjoying the game but, with repetition becoming a problem so quickly, I have no further interest in playing.
This game is way too simple. I've played one match of each game mode and I feel I've experienced the entire game. The difficulty is very low, and the "catch the liar" game mode is extremely simple and straightforward. I do not recommend this game.
Hey Claude, come up with a creative game concept and build it. ... Make it better. ... Fix the bug when generating a room with 3+ chairs. ... Great, release it on Steam. Make it cheap. -------------------- Look, as a software engineer this is obviously AI coded. That said, we shouldn't judge games based on that. This is the world we are living in now and we will *never* go back to pre-AI days. Yes, today we can see some obvious signs to how it was made by AI but these will quickly go away and every company will be using AI anyway, there's no reason not to. Hopefully Steam will find a good way to make the good games be pushed up people's feeds and bad games (human or AI) be less visible. And now for the proper review: The game itself is actually not bad. I like the idea, Claude. Well done clanker. It does take a bit of logic to place people in their locations (though the instructions are terrible and UI is even worse), the weapon finding is a hilariously stupid AI idea, and then the crime solving part is.. ok, I guess? It's just that currently the game will be very repetitive. There aren't many types of hints so once you've solved it a couple of times the game is no longer interesting. "Difficulty" doesn't really do much, the Classic game option is redundant and silly - just keep Investigation, and introduce new mechanics and hints. Maybe even a story..? It's basically free to make for clankers. Anyway, I do appreciate this game, well done Claude. I can only imagine where AI-built games will be a year from now, and I am very excited for those a few years down the line.

It's not really a 50/50 blend of both concepts, but lightly borrows a little bit of Clue and Sudoku, in order to make something different. Unfortunately, it winds up being kind of bland, without many options available for changing up the gameplay. [h1]Gameplay[/h1] There's two game modes, but both start with the same goal. Using the various descriptions, find out where each suspect is on the board. I wasn't sure how Sudoku fit at first, yet it's pretty simple. Nobody on the board will have another person standing in the same row or column as them, ignoring the victim. For the basic version, whoever was in the room with the victim was the murderer. Investigation mode switches into a second phase, with three possible murder weapons. Each suspect will provide a statement, and from what I've seen, anything that doesn't mention the weapon will be correct, so they can be ignored. All statements about the weapon have to be checked, but based on wording, there will be a combination where one weapon will have a single lie told. This is the correct weapon, and whoever told the lie was the murderer. Despite what others have said, I've seen a difference in the hard clues. The structure and wording covers things the easier difficulties didn't, such as one person being further left than another. To me, it seems like it was meant to be more complex. When working on these hard puzzles, I have made a mistake, and somehow screwed up the solution. Originally, I thought this was all my fault, but now I don't think that's the case, because I discovered a clear contradiction, which I used for two of my screenshots. A puzzle was made where a suspect is in the same room as the victim, yet also next to an object that wasn't in there. This is a massive problem. If the logic can generate an obviously impossible puzzle, there's no way to know any other one will work either. https://steamcommunity.com/sharedfiles/filedetails/?id=3761814593 [h1]Controls[/h1] Although I could easily see this title working with a mouse, I was surprised to find it very easy to play with my controller as well. It can be a bit slow moving to each box on the largest grid, but it's otherwise intuitive and responsive to mark squares with the corresponding characters. You can block out squares if you want to, yet it's not necessary for making progress. What's important is placing all the characters in their correct spot, and if you've chosen Investigation Mode, selecting the correct murder weapon and suspect. [h1]Story[/h1] Since it borrows from Clue, this would have been the means to incorporate a bit of plot into the game. However, oddly enough, the developer uses the same character portraits for each map, and even the first letter in everybody's name. Nobody winds up having a consistent name, like Professor Plum or Colonel Mustard, meaning there's no means of establishing defined characters. Instead, the guy in red whose name starts with an A might be Amir in one case, and Alvin next time. If each character is always going to look the same, and be put into the same order every case because the names are listed alphabetically, then there's no point in making slight alterations to what those names are. https://steamcommunity.com/sharedfiles/filedetails/?id=3761813265 [h1]Visuals[/h1] Sudoku is nothing but a grid of numbers, so you'd think various locations filled with furniture would be more interesting to look at. However, because every puzzle is randomly generated, and the rules for making them don't consider real-life logic, it leads to arrangements that don't look natural or realistic. Rooms often jut into one another in odd ways, making you wonder where the doors would be, and how you'd ever get into some places. Even though I played several puzzles, because it's common to have similar types of furniture in one place, I'd have to refer to the chart to distinguish between them. You wouldn't believe how many iterations of chairs there are for a game with four maps. Also, unless you have a fairly large monitor, it does get more difficult to see everything on the largest grids because everything has to shrink in scale. [h1]Sound Design[/h1] Despite having four locations, the same song plays no matter what set-up you create with the settings. It's fitting enough, as a calm piano tune plays in the background, although it might be a touch calm for the scene of a murder. Regardless, with only a single tune in the entire game, if you were to play for the length of time suggested with achievements for clearing 100 puzzles, this song will wear its welcome out far before then. I'm once again a bit surprised how the developer wanted to diversify the settings, yet didn't accompany it with matching tunes. Even with the music, it's an incredibly quiet game, as it's not very loud by default, and there's no other sound effects as you work through the puzzle. https://steamcommunity.com/sharedfiles/filedetails/?id=3761813689 [h1]Pros[/h1] 🌟 Investigation Mode makes the game feel more like Clue, but it barely adds anymore time or complexity to the puzzle you've already solved. Figuring out everyone's location is the main focus. 🌟 It's a novel idea for the kind of logic puzzles you'd solve in grade school, “Johnny isn't in space A or D. Tim was not standing next to a girl.” [h1]Cons[/h1] ❌ Windows are one of the hardest things to check for. They aren't as obvious as a piece of furniture filling an entire square. ❌ It can be a bit annoying when a clue means a person could be in as many as a dozen different places. ❌ Having to check between all the variations of chair gets old after a while. [h1]Tips[/h1] 🔍 When describing a person's proximity next to an object, the person can't be in another room. For instance, if a potted plant is in the kitchen, and there's an open square to the right in the office, that wouldn't be a valid place the person could be. Otherwise though, any other opening is valid. 🔍 Certain objects cannot overlap with people. They sort of count as free squares, because you know a person would never be there. [h1]Final Thoughts[/h1] Even before I discovered an impossible puzzle, I was starting to feel a bit bored with the randomly generated puzzles in CD. Once you've figured out the game's logic and approach to creating puzzles, it becomes easy enough to solve them. The bigger issue is that the different maps don't in reality change anything, it's only a surface level alteration. Unless you wanted to earn the achievements, there's no mechanics or in-game progress to reward your commitment. Establishing distinct characters and developing a series of murders to solve might have been a way to hold someone's attention longer. However, adding the problem of something being wrong with the internal logic to create hard puzzles makes the current release almost unplayable. I never had this issue on the other difficulties, but not being able to trust the puzzle generator is a massive deal breaker.

Maps look way too dark, everything looks AI generated, maps are really simple
Its cheap, but its mostly AI, doesnt feel like a good game to me. Ive seen unsolvalbe puzzles. Theres defo better versions of this puzzle out there
Cheap, but still not worth the price in my opinion. It attempts to blend the games of Sudoku and Clue, and somehow manages to suck the fun and difficulty out of both games. It lacks a comprehensive tutorial, leaving you to flounder through your first few puzzles, but once you understand the rules every single game plays out the exact same with no challenge or intrigue to keep you playing. The "hard" puzzles simply add more suspects and larger rooms, leaving the game to follow the exact same easy flows of logic with no real added complexity. Another issue is the AI-slop looking character art. Lack of cohesive style and the same look you would get from a low-quality AI generation model that makes the whole product feel gross just by association. If I had paid more attention to this before buying I would have never made the purchase. Even with the low price I still feel cheated.
They've changed the game with a recent "update" and removed any actual story/progression from it. They changed the name and the new name is worse than the original (CluDoku). There are no instructions and it's counterintuitive how to play. It lacks the sophistication I was expecting based on the original premise. I feel it was unfair to change the gameplay after people purchased it.
Very disappointed. Good premise for a brain teaser but not when the logic algorithm doesn't follow real logic
