My React Native version of Mathler. Built using Expo and Typescript. Managed by bun.

bun install
bun start (This will start the local server, then download the Expo Go app to run it on your device)

I uploaded a version of the code base as a Snack, it runs on iOS, Android and Web: https://snack.expo.dev/@jenshandersson/mathler-snack

Extracted most of the game logic and testing using Jest unit test. Normally my test philisophy is to unit test "logic", snapshot or other UI testing often becomes a pain when iterating and re-designing UI, so try and avoid it. There are still a lot more to test, and some edge cases to handle like running out of problems.
