You get a floor plan, a victim and a handful of statements. Everything else you have to earn.

CRIDOKU takes the base rule of Sudoku — exactly one per row, exactly one per column — and lays a crime scene over it. You place the suspects until a single square is left: that is where the victim lies. And whoever ends up sharing that room did it.

The cases grow with you. The first plan has five rows and is cleared in a coffee break; the last has nine and asks you to hold two clues against each other that say nothing on their own. In between lie ten locations, from a country house in the fog to a fairground after closing time.

The same cast investigates throughout: thirteen faces that keep coming back. Today's victim is next case's suspect.

What we stand behind

Every case in this volume was machine-checked before it went to print: exactly one solution, reachable without a single guess, and no clue that could be dropped. If you are stuck, what is missing is the next inference — not luck.
