## What's happening here?

Guess the [Fastly POP](https://www.fastly.com/network-map/) in 6 tries. After each guess, the color of the tiles will change to show how close your guess was.

The game logic is implemented in a Fastly Compute service written in Rust 🦀 and compiled to WebAssembly, with daily POP challenges retrieved from a [Config Store](/learning/concepts/edge-state/dynamic-config#config-stores).
