What is Murdoku?

Murdoku is a logic puzzle by Manuel Garand that combines a crime scene map, suspect cards, and spatial clues. The official online version presents cases by difficulty and currently focuses on English UI, so this site adds a bilingual reading layer for players who want clearer rules.

Why this guide exists

The official game is visual and charming, but the rule text is brief. If you miss the meaning of a word like beside, south of, alone, or shelf, a puzzle can feel ambiguous. The pages here translate the concepts into practical solving steps.

Tonight-ready roadmap

Use the rules page first, then play an official very easy puzzle with the strategy checklist open. Once you can place suspects without trial and error, move to the puzzles page for more cases and printable practice.
