These terms describe the free browser game and its current limits.
Using the game
You may play for personal, noncommercial enjoyment. Online rooms are temporary and may become unavailable when a player disconnects, the server restarts, or the service is maintained. Random matchmaking pairs you with another visitor. There is no chat or exchange of contact information.
Fair play and access
Do not use automated requests to overload the server, interfere with other rooms, or attempt to use another player's seat token. A room admits one Black player and one White player; the server checks legal moves and turn order. Do not create multiple identities to manipulate the leaderboard or arrange artificial wins. Ranked turns have a 90-second limit. Leaving, resigning, or timing out counts as a loss; a draw ends a winning streak.
Availability and results
The site is provided as available. Game results are for entertainment and are not official tournament records. The operator may update game rules, features, and availability. Report a problem through the contact page.
Privacy
