SynChess

SynChess is a free multiplayer chess game with 16 tables per channel. Players take part on as many boards as they like, or just watch. Comes with a bot opponent with variable brain capacity. Includes instant replay and the ability to clone a board to a new table to handle "what if" situations. You can design your own board and piece art if you like. Users earn normal chess ratings (non-binding!)

This game is part of the Synthetic Reality "Arcadia" family of games. (http://www.synthetic-reality.com/arcadia.htm) Players add additional channels at will using the integrated MIX server. Arcadia itself provides all networking support, in addition to text chat, voice chat, web browsing, and a parallel existence 'park' environment for serenity, duck-feeding, and paintball while you wait for other players to show up. Arcadia allows you to create a personal identity with which to expose your current emotional state, and maintain a diary of other players you have met in the game.
