Questions
Before you buy
Is the demo the same game as the book?
Yes. The demo uses the same puzzle engine that built the book: the same rules, the same clue style and the same one-solution guarantee. In print you simply work with a pencil on the grid.
What does “Generate a Deadoku Puzzle” do?
It builds a brand-new, solvable case on the spot — a random house plan, a random cast and a fresh set of clues. Each one has exactly one solution, just like the cases in the book.
How do I know who the killer is?
Work out where all eight suspects stood. The killer is the only suspect standing in the same room as the victim. Press “Check Solution / Reveal Killer” and the page will tell you whether you’ve cracked it — or show you exactly what doesn’t add up.
Do I need anything to play the paperback?
Just a pencil. Every puzzle fits on a single page, and all solutions are in the back of the book.
