tweeckie is an innovative JavaScript platform enabling people to play with a friend by just sending him a direct link.
The whole engine heavily relies on HTTP Push techniques and aims at full cross-browser compatibility. A developer API exists so that any kind of 1-on-1 game can be plugged into tweeckie. A live chat is also available while playing.
Chess, Checkers and Othello (Reversi) are currently bundled with tweeckie.
