Krimdoku

Manhunt meets Sudoku.

There was a murder last night. A handful of suspects, one victim, a floor plan full of clues — and only one arrangement that truly adds up. Grab your magnifying glass.
Krimdoku marries the rigor of Sudoku with the suspense of a whodunit. Every suspect leaves a clue — "…was sitting on a chair", "…was in the same room as Bryson", "…was NOT beside a wall". You reason, cross out and place, until every person stands on exactly one tile. Whoever ends up alone with the victim in a room is the murderer.

★ OVER 140 HANDCRAFTED CASES
More than 140 ready-made mysteries await — from a cosy 4×4 up to a sprawling 12×12, across three difficulties.

★ A MIX OF SUDOKU AND LOGIC PUZZLE
Pure deduction, zero luck: every case has exactly one solution, provable by logic alone. As in Sudoku or Murdoku — one person per row and per column.

★ A FRESH CASE EVERY DAY
The daily mystery: one date, one board, one culprit — the same case for every detective in the world. Flip through the calendar, catch up on days you missed and keep your streak alive.

★ BUILD YOUR OWN — THE EDITOR
Paint rooms, floors, objects and windows onto the board, create suspects and assemble their clues. "Check" tells you whether the case is uniquely solvable, "Play" tests it instantly, "Save" files it in your archive.

★ SHARE IT — COMMUNITY CASES
Upload your creation straight from the editor: every case is moderated and its title translated into all six languages before it goes live. Browse what other detectives publish, filter by stars, size and status, and rate solved cases with stars and tags.

★ ENDLESS CASES — THE GENERATOR
Out of files to crack? The generator builds guaranteed-unique cases on demand — 14 themed settings from mansion to zoo to ski resort, three difficulties, boards from 4×4 up to 12×12.

★ TAKE THE CASE TO PAPER — PDF
Print any mystery as an A4 case sheet: the crime scene, every suspect's testimony and a black-and-white deduction grid to crack in pencil — plus an optional solution sheet, sealed until you need it.

A TRIBUTE TO THE INVENTOR
Krimdoku is a freely interpreted fan version. The brilliant core idea — fusing Sudoku logic with a murder case — comes from Manuel Garand. This project is not affiliated with him. If you enjoy the principle, support the inventor and buy his books!
