Building: Dice Chess for Fire TV

An offline game for Amazon Fire TV, built with TypeScript and React Native for Vega. Two people share one screen and one remote, or one player takes on the on-device bots. Roll three dice, choose your moves, and capture the king.

The app includes an interactive tutorial, save and resume, and adaptive music. The Scala engine behind it also powers the web game.
