Bot matches, and online matches on the official servers, right here. Community servers and hosting your own need the desktop game.
A one-time download of about 16 MB, and each map the first time you play it (up to 24 MB); your browser keeps them for next time.
Needs a recent Chrome, Edge, Firefox or Safari on a computer with a keyboard and mouse. Click the game to capture the mouse; Esc releases it.
Runs slower than the desktop game, especially on laptops; lower the render scale under Graphics if it stutters.
Online play needs a browser with WebTransport. Joining a server downloads the maps it plays that you don't have yet, after you agree. Keep the tab in front while you play: a background tab stops sending your moves and the server lets you go.
