Leagues & leaderboards
Join a weekly league ranked by steps. Follow your friends through the same murder case and see who solves it first.
The ladder
Leagues are weekly. Walk more than most of your league and you move up. Steps are the only thing that counts. Not pace, not routes.
7 leagues in all, from Copper to Midnight.
The board
Your league, live through the week. Steps sync from Apple Health, so the board counts the walking you actually did.

Steps. Your step count syncs from Apple Health, and that’s the only number the board uses.
Every Monday at 12:00 UTC. Steps count by calendar day, Monday to Sunday, so your Sunday walk still counts.
Each league is split into groups of up to 30 detectives. At the end of the week, the top quarter of a group (up to 7, and always at least one) moves up a league and the bottom quarter (up to 7) moves down. Everyone else stays put.
No. Friends see your progress and your verdict poster. The poster never names the killer.
