Questions

Is Poseidia free to play?

Yes. Poseidia is free and plays in your browser on poseidia.vercel.app. Foundplay links to it but doesn't host it.

Do I need to download Poseidia?

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

Is Poseidia safe?

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 Poseidia on my phone?

It needs a keyboard, so it's best on a computer.
