Murdoku: The Sudoku and Cluedo Mashup With 80 Murder Puzzles 2026

Murdoku is a paper-based puzzle that combines the logic of sudoku with the murder-mystery mechanics of Cluedo. Created by Manuel Garand, it challenges you to solve 80 different assassination cases using a grid, a set of suspects, and a series of clues. If you enjoy brain-teasers that demand careful deduction, this might be your next obsession.

What Is Murdoku?

Murdoku is essentially a sudoku variant where each row, column, and region must contain exactly one suspect, one weapon, and one location—just like the classic board game Cluedo. But instead of rolling dice and moving around a board, you work with a printed grid and a list of clues. Each puzzle presents a murder scenario: a victim, a set of suspects, and a collection of objects and rooms. Your job is to figure out who did it, where, and with what.

The game is available in a book titled 80 acertijos de lógica y asesinatos (80 logic and murder puzzles), sold on Amazon and other retailers. A small sample is also available on the official Murdoku website, so you can try before you buy.

How Does Murdoku Work?

Each Murdoku puzzle gives you a grid, typically 9x9, divided into smaller regions. You also get a list of suspects, weapons, and rooms. The clues are statements like "The candlestick was not in the library" or "Miss Scarlet was in the same row as the revolver." Using these clues, you must place each suspect, weapon, and room in the correct cell, ensuring that no row, column, or region contains duplicates—just like sudoku.

The twist is that the clues are often indirect and require you to eliminate possibilities. For example, a clue might say "The person with the rope was either in the kitchen or the conservatory," which forces you to use other clues to narrow it down. Some puzzles also include fixed elements like plants, sofas, or pools that serve as landmarks and further restrict where characters can be placed.

Key Mechanics

• Grid-based placement: Each row, column, and region must contain exactly one of each suspect, weapon, and room.
• Clue interpretation: Clues are often negative ("not in the study") or relational ("next to the dagger").
• Fixed objects: Items like plants or furniture provide additional constraints.
• Difficulty progression: Puzzles range from easy to fiendishly hard, with some requiring deep logical chains.

Because each scenario has its own unique layout and set of clues, no two Murdoku puzzles are alike. The variety keeps the game fresh and challenging.

Why Murdoku Stands Out

Murdoku is not just a sudoku clone; it adds a narrative layer that makes logical deduction more engaging. Instead of abstract numbers, you're dealing with characters and objects, which makes the puzzle feel like a story. The murder-mystery theme also provides a satisfying payoff: when you finally deduce the culprit, you've solved a crime.

Moreover, the game is entirely paper-based, making it a great screen-free activity. It's perfect for fans of logic puzzles who want something more thematic than traditional sudoku.

Murdoku vs. Traditional Sudoku and Cluedo

As the table shows, Murdoku carves out a niche by merging the solitary logic of sudoku with the thematic intrigue of Cluedo.

Who Is Murdoku For?

Murdoku appeals to puzzle enthusiasts who enjoy sudoku but want more narrative flavor. It's also great for fans of detective fiction and mystery games who prefer a solo experience. The puzzles can be quite challenging, so they're best suited for teens and adults who don't mind spending time thinking through complex clues.

If you're new to logic puzzles, you might want to start with easier sudoku variants first. But if you're a seasoned solver looking for a fresh challenge, Murdoku offers a compelling twist.

Where to Get Murdoku

Tips for Solving Murdoku Puzzles

Start by identifying the most restrictive clues—those that directly place a suspect or object. Then, use the process of elimination to fill in the rest. Pay attention to negative clues, as they often unlock key deductions. And don't be afraid to use pencil, since you'll likely need to erase and revise.
