How a case works

Think of it as murder sudoku with a story

No guessing, no luck. Every clue you need is on the page.

  1. Place every suspect

    Each case is a floor plan and a stack of statements. Put every suspect on the one square that fits what the witnesses said: one per row, one per column.

  2. Find who was alone with the victim

    When the board is complete, the victim's room lights up. The only other person in it is your killer.

  3. Name the motive

    Read the evidence and prove why they did it. Then the case is closed and the next one lands on your desk.

In the file

One noir mystery, six chapters deep

Everyone had a chance. Only one had a motive. Your job is to prove which one.

  • 33 hand-built cases

    Six chapters of one noir story about a single insurance file, from a 1947 hotel to Christmas 1949.

  • Pure logic

    Every case has exactly one answer, and you never need to guess.

  • A new trick every chapter

    Each chapter adds a technique, all the way up to liars whose every claim is false.

  • The Night Beat

    A new case every night, the same for every player, with a calendar of past nights and a streak to keep. Easy on Monday, fiendish on Sunday, when the killer lies.

  • Hints that teach

    Stuck? Get the next real deduction from your own board, explained, not the answer.

  • Made to be comfortable

    Pencil notes, ✕ marks, undo, and a colour-blind-safe palette. Plays on phones, tablets and foldables, upright or sideways.
