Two things worth a look. Both work in any browser — no sign-in, nothing to install.
Syndicate
A Prohibition board game. Four outfits carve up one city — claim turf, dodge the police, take ground off each other. Start with First Night and it teaches you as you play.
Revive AI
Drop in an old damaged photograph and get it back cleaned up, with optional colour. Takes about twenty seconds.
On an iPhone? Open either one, tap Share, then Add to Home Screen — it installs like a normal app.
