# Circuit Playground Express Treasure Hunt ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/058/049/medium800/express_where_are_they.jpg?1532537843) Oh no! Someone hid a bunch of treasures all over the place. How are you going to find them? Well, it just so happens those "treasures" are actually Circuit Playground Express boards that are sending out their location. So all we need to do is create a "hunter" Circuit Playground Express to sniff them out. Then the hunt is on! In this guide we will go over how to create programs to act as the "treasure" and the "hunter". Then, using multiple Circuit Playground Express boards, we can create a fun game by loading the "treasure" program on several of these and hiding them. By loading the "hunter" program on another Circuit Playground Express, we can use that to search out and find all the treasures. The game is over when all treasures have been found. _ **Let the Treasure Hunt begin!** _ ![](https://cdn-learn.adafruit.com/assets/assets/000/058/096/medium800/express_treasure_chest.jpg?1532563859 https://openclipart.org/detail/299034/treasure-chest-2) - [Next Page](https://learn.adafruit.com/circuit-playground-treasure-hunt/talking-with-infrared.md) ## Featured Products ### Circuit Playground Express [Circuit Playground Express](https://www.adafruit.com/product/3333) **Circuit Playground Express** is the next step towards a perfect introduction to electronics and programming.
