Most games made with AI are single-player: one prompt, one person, one screen. These 20 let you play with other people, online or in the same room. They are all free browser games, so the only setup is sending a link. The tags on each game page say whether it is multiplayer or co-op; this list takes those.

FAQ
How do I play with friends?
Open the game, then send your friends the same link. Some games give you a room code to share, like Killer Bufo; others, like fly.pieter.com and the MMORPGs, put everyone in one world.
Are they free and without download?
Yes. All 20 are free and run in a browser.
Can AI really make a multiplayer game?
Yes, these are proof. Multiplayer needs a server to keep players in sync, which used to be the hard part. Peter Yang added it to Turbo Tails with one short prompt to Claude Fable 5.2.
