The browser client offers Tutorial, Campaign, Custom Game, and Editor. Use a mouse and keyboard. Click the game canvas to focus keyboard input and enable music.
Your browser saves belong to that browser profile and website address. Clearing site data removes them. Use the in-game import and export controls to keep backups; another browser does not automatically share those saves.
Finish a save before closing
Use the game’s Quit control and wait for storage to finish. If a write fails, the game offers a retry or a way to leave without confirming a save. Refreshing or closing the tab cannot wait for those pending writes.
Play online
Choose Play online in the game to enter the online hub. Casual rooms and queues support guest play. Register an account to join rated queues and appear on the player leaderboards. Available sign-in methods are shown by the instance.
Use quick match to search for opponents, or create a room and share its invitation code. Some queues can offer AI opponents when human players are unavailable; check the queue information and your opponent preference.
The online app keeps player profiles, public match history, and leaderboard pages. Rated queue results change ratings only after engine verification. Room matches are unrated, and a provisional rating means the system is still learning a player’s skill.
Browser play is in early access. A reconnecting match shows its connection status and grace time in the game. Do not close or refresh deliberately during a match: leaving through the game quits your seat, while unexpected connection loss depends on reconnecting before the match’s grace expires.
If the game has trouble running
Try the software renderer using the game address with ?renderer=software. If a save fails, export a copy where the game offers that option. For a bug report, include your browser, game version, the action that failed, and any on-screen message.
