"Chapayev game" (Russian: "игра в Чапаева") is a game played on a checkerboard, a hybrid of checkers and billiards.

Game rules and funny details are present on Wikipedia

The project has been started as a programming exercise while studying Javascript and various JS libraries. In the same time I just wanted to play Chapayev with friends, so I decided to implement multiplayer version as well.

JS libraries used so far:

• Raphaёl -- for game graphics and animation
• Socket.io -- for client/server interaction suitable for any browser
• Node.js -- for server side
• Knockout.js -- for structuring the code, introducing data model in UI using MVVM pattern
• jQuery -- for querying the DOM, providing templates for Knockout.
• Sylvester -- for vector/matrix operation needed for collision resolving.
