Play 1500+ murder sudoku cases, daily challenges and themed crime scenes. Place suspects, follow clues and solve with pure logic.
GridNoir turns murder sudoku into a large, living logic puzzle collection.
Play 1500+ cases across themed casebooks, from classic crime scenes to cruise ships, hotels, campuses, trains, museums and more. Open a daily challenge, read the suspect cards, inspect the rooms and place each person on the grid.
Each suspect belongs in one row and one column. Every clue narrows the possibilities until the victim, the culprit and the crime scene finally make sense.
No guessing. No account. Just deduction.

I’m doing it correctly but it says it’s wrong I can’t pass the level

Okay game

Why not more stars?It’s because the rooms in the puzzles are usually not very realistic. And that takes much of the fun out of the game.For example, a hallway should look like a hallway. But too often a hallway is just a random geometric shape that’s off to one side.On edit: I really do like the idea of this game. And I tried to get into it. But as I noted earlier, the rooms are just random shapes. It takes all the flavor out of the game.So with some regret, I reduced my rating by a star.

Too predictable

Played a few games and the clues are ridiculous. “This person is in row and column.” So lame. Would not recommend.
