10 gamesAbout this genre
Retro platformers emulated or rewritten for the browser. Every game here runs in a browser tab: no installers, no launchers, no account. The setup label on each card tells you whether it starts instantly, needs a first-load download, or wants data files from a copy of the game you own.
We link to the original project pages and host no game files. If a link has stopped working, tell us through the submit page and we will check it.
