Kludoku — the murder-mystery logic puzzle

A murder. A sealed scene. Pure logic. Kludoku crosses a whodunit with a Sudoku-style placement grid: read the suspects' testimonies, deduce where every person stood — exactly one per row and per column — and name whoever ended up alone with the victim.

How to play

1. Read each testimony: rooms, furniture, rows, columns and neighbours.
2. Place suspects on the map; use X marks and pencil notes to reason.
3. When everyone is placed, accuse the one alone with the victim.

Daily cases & competition
