Is SE!ZE free to play?

Yes. SE!ZE is free and plays in your browser on letsseize.com. Foundplay links to it but doesn't host it.

Do I need to download SE!ZE?

No. It runs in a browser tab, with nothing to install.

Foundplay checks its link every few hours and gives it a daily safety check (malware blocklists, downloads, crypto miners, parked domains and fake virus warnings), and hides the game at once if that check fails. No check can promise a site is safe: if a game asks you to download something or for a password, leave it.

Can I play SE!ZE on my phone?

Yes. It has touch controls and plays in your phone's browser, with no app.
