# Treasure hunt app for a team-building day

A QR-code treasure hunt for a team day. Each scan adds a stamp, and a full card is redeemed for a prize.

## The problem

The team day needed people up and taking part, not sitting through a presentation.

## What we did

We built a treasure hunt around QR codes at checkpoints. Each scan adds a stamp to the player’s card, and a full card is redeemed for a prize. Players join from the phone camera, with nothing to install.

## The result

The day runs as a game: people move, collect stamps, and redeem a prize when the card is full.
