Extensible multiplayer backgammon game written in JavaScript

Current version: 0.6

See CHANGELOG for recent changes.

Volunteer needed to host live DEMO.


  • Challenge friends or play with strangers online without registration and game setup process.
  • Fair gameplay that is as close to real game as possible:
    • no visual hints (eg. for allowed moves);
    • no pip counter;
    • quality random generator.
  • Extensible and modular engine that would allow the open source community to implement different variants of the game as known in different countries and different user interfaces (eg. themes).
  • Lightweight - playable on any device, even old ones - anything that can run a modern browser;
  • Works in browser @ PC & Mobile;

You can try the game locally or deploy it to your own server.


How to install

To host the game on your own server or test it locally for development, you need to install the main backgammon.js package. It includes both the backgammon.js server and client.

There is no need to install the client separately, as it is served automatically from the server via HTTP. Client should work in modern browsers of both desktop PCs and mobile devices.

The universal way to install the server is:

  1. Clone repository locally

  2. Change working directory to the local copy of the repository

  3. Run:

     npm install
     npm start

The game server has been tested to work on the following platforms:

Follow the links above for more detailed installation instructions on those platforms.
