## What is Chalkline?

A murder has been committed. Everyone in the building was standing somewhere when it happened — and exactly one of them was alone with the victim.

Chalkline gives you a floor plan, eight suspects and a handful of statements. Work out where every single person stood, and the killer reveals themselves.

HOW IT WORKS

Each suspect tells you one true thing. "He was next to a TV." "She was alone with Carla." "He was exactly two rows north of Ivo." Cross-reference the statements, place everyone on the map, and only one arrangement can possibly be true.

Then apply the one rule that matters: the victim was alone with exactly one person. That person did it.

NO GUESSING, EVER

Every case is checked by a solver that only makes moves a person could make on paper. If a case is in the app, it can be reasoned out from start to finish — no trial and error, no lucky guesses, no dead ends. Difficulty is measured by how much deduction a case genuinely takes, not by how many clues we deleted.

WHAT YOU GET

• 60 cases in the archive — 20 easy, 30 medium, 10 hard
• A brand new case every single day
• 12 locations: a mansion, a hotel, a yacht, a museum, a cinema, an office, a gym, a campsite, a bowling alley, a car dealership, a burger joint and an electronics store
• Hints that teach instead of spoiling: they tell you which suspect to work out next and whose note holds the answer, so you still make the deduction yourself
• A streak for solving the daily case
• Finished cases stay in your files, and you can replay any of them
• Complete in English and German
• Plays entirely offline — no account, no sign-up, no connection needed
