Fullscreen isn't working
The game plays best filling the whole screen. If fullscreen won't turn on, or keeps turning off, the fix is usually one keystroke away.
Use your browser's fullscreen shortcut
On Windows and Linux, press F11. Most browsers also have a fullscreen option in their menu if you'd rather click.
On a Mac, use the green button
Click the green button in the top-left corner of the browser window, or use the browser's View menu to enter full screen.
Know that Esc exits
Pressing Esc leaves fullscreen in most browsers. That's by design, not a bug. If you keep dropping out of fullscreen, Esc is probably why.
If fullscreen genuinely won't engage, tell us your browser and system and we'll look into it.
