Memory & Thinking

Platform Lost & Found

Follow the locker exchanges to find where a parcel finished or where it started.

Take a shift at a station claim room, where each transfer slip swaps the contents of two lockers. Track a parcel forward, or trace its journey back from a known destination.

Two ways to play

Collect a parcel
Inspect the open lockers and remember the requested parcel. After the exchanges, choose its final locker.
Trace the sender
The arrival ticket names the final locker. Remember the exchanges, then trace them in reverse to find the starting locker.

Your session

Each session has 12 rounds. Choose from three difficulty settings and try a guided practice round before you begin.
