You are on the backup site for Any posts, moves, or other changes you make here will not be permanent, because the pages and database from the main site will be backed up here every midnight EST. Additionally, things may not be working right, because this site is also a testbed for newer system software. So, if you are not here to test, develop, or merely read this site, you may want to change .org to .com in the navigation bar and go to the main site.

The Chess Variant Pages


Jocly is a Web platform dedicated to 2-players pure abstract strategy games. Using its base Chess module, a large range of variants can be run.

Things you can do with Jocly:

Available Chess variants

The source code of all those variants is available to developers and can be reused to create new variants.


Jocly uses pure HTML5 web technologies. This means the browser does not any plugin like Java or Flash to run.

Most Jocly games, including all Jocly chess variants implement both a 2D and 3D interface. The 3D interface, implemented using WebGL, is the default, but due to technical constraints, running a game from Internet Explorer, a smartphone or tablet, Safari with WebGL disabled or from a computer with an old graphic card, the system defaults to 2D.

When playing live on the main site, it is possible to enable the webcam chat, using the WebRTC technology. This way you can see your opponent directly into the 3D scene, or, if in 2D, next to the board. Note that this feature requires both sides to be running Firefox or Chrome as a browser.
