# Solid Chess



This is a decentralized Chess game, build on top of [Solid](https://solid.inrupt.com/).

No central sever is required to run or set up a game.

All personal data about the game is stored on your POD.

Requests to join a game are sent to the inbox of your opponent directly.

You have two types of games: a non-real-time and a real-time game.

With a non-real-time game all updates are sent to the inbox of your opponent,

who can interact with it when (s)he wants.

With a real-time game [WebRTC](https://webrtc.org) is used to allow for a direct communication between two instances of the Web app.



The game is available in the [browser](#browser) and [terminal](#cli).

Check the [live version](https://pheyvaer.github.io/solid-chess/) or one of the following screencasts:

- [real-time game via Web app](https://streamable.com/j951d)

- [non-real-time game via CLI](https://streamable.com/x7fo0)



WARNING: The "Clear inbox" button **removes all files with (chess) game data** in your inbox! So be careful!



## Documentation



- Code documentation can be found [here](https://pheyvaer.github.io/solid-chess/docs/).
