Murder Matrix
A cozy logic deduction puzzle for iOS. Designed and built solo.
Overview
Murder Matrix is a cozy logic-deduction puzzle for iOS. Each case asks you to place suspects on a small grid based on the clues they give, and the empty square reveals the victim. It’s a small, careful game, closer to a crossword than a thriller.
Designed and built solo. Pure SwiftUI, no third-party dependencies, built from first principles.
What’s in it
- Six original locations, each with its own pastel palette and floor plan.
- Procedurally generated puzzles with one guaranteed solution. Every case is unique.
- Three difficulty tiers: Rookie, Detective, Mastermind.
- A daily challenge with a shareable seed. Compare your solve time with friends.
- No ads, no tracking, no accounts. Just puzzles.
How it plays
Read the clues. Each suspect tells you something about where they were standing. Place them on the map; no two share a row or column. When all but one suspect is placed, the empty square reveals itself. Whoever shares that room is the murderer.
Stack
SwiftUI for the entire UI. SwiftData for local persistence. CloudKit for optional cross-device sync. The game has no backend service, no analytics, and no third-party SDKs of any kind.
