Murdoku

Here is an excerpt from Murdoku's description on the game's official website:

Sudoku meets murder mystery. Place the suspects on the crime scene and reveal the killer.

Every case gives you a lineup of suspects, a full-color crime scene, and a detailed solution at the end.

Here’s what a typical spread looks like.

• A cast of suspects and the victim, each with clues about where they can or can’t be on the grid.
• A crime scene with rooms and objects, where everyone needs to be placed. In classic sudoku fashion, there's only one person per row and per column.
• Clear, full step-by-step solutions for extra clues or when a puzzle completely stumps you.

NB: While we found mention of a Murdoku puzzle published on November 19th, 2025, we could not confirm that it is the date of the very first Murdoku puzzle that was published online.
