CULLPRIT - Deduction Puzzles

A murder, a grid, and one person who cannot be telling the truth.

Cullprit is three deduction games in one, each with a fresh case every day. You do not read clues and tick boxes — you solve a puzzle to earn the evidence, then work out who did it. The deduction is yours. The app never crosses anyone off for you.

THREE GAMES, THREE WAYS TO CATCH SOMEONE

BONEYARD — Northmere House
Lay dominoes across the rooms so every room's rule holds. Five accounts of the evening, and only one that cannot be true: the person whose bone never left a single room.

SCENES — The Grand Hotel
Place everyone on the floor plan from the clues, one to a row and one to a column, then work out who was carrying what. Whoever holds the murder weapon did it.

TRACKS — Follow the line
Draw a single railway line that matches every row and column count. The line passes over letters, the letters spell a word, and the word clears suspects until one is left standing.

THREE DAILY CASES, ALWAYS FREE
One from each game, the same for everybody, with its own streak. Share how you did without giving the answer away.

A HUNDRED CASES TO WORK THROUGH
Forty Boneyard cases, forty Scenes and twenty Tracks — the casebooks, with a message hidden across each season and a final culprit waiting at the end of the line.

PLAYS ANYWHERE
Every puzzle is inside the app, so it all works with no connection at all. No adverts. No account. Nothing to sign up to.

BUILT FROM THE BOOKS
Cullprit began in print, and every case here was checked by the same solver the game uses. Each has exactly one answer, and there is always enough to find it — no guessing, and never two suspects who both fit.

Solve the puzzle. Name the culprit.
