CaperTrails
What is CaperTrails?
CaperTrails is a detective puzzle game built around grid maps of a city. In each case, you use timing and route logic to determine whether a suspect could have reached the crime scene. The core rule is simple: one block equals one minute.

The one-block-one-minute rule gives every move weight, but airtight logic demands each clue be perfectly placed.

Quick, clever little puzzles that fit nicely into a commute – easy to pick up, satisfying to crack.
How to play CaperTrails
Each case gives you a map, a list of suspects, and clues involving times, positions, and directions. You trace possible paths block by block, turning distances into travel times. By reconstructing each suspect's movements, you work out who could have been at the crime scene at the right time.
Tips & strategy
- Treat every block as one minute and count route lengths carefully.
- Start from the crime scene and work backward to see which starting positions are possible.
- Use clues about direction and position to eliminate suspects early.
- Compare each suspect's available time window with the shortest possible route.
- Keep paper and pencil handy; the game is designed for careful deduction.
