About run3.gg

run3.gg is a dedicated gaming destination built around one iconic experience: Run 3, the gravity-defying 3D cosmic runner developed by Joseph Cloutier. The domain has hosted the game since 2023, and this version of the site was rebuilt in September 2026 as a pure, ultra-fast static site powered by Next.js and Cloudflare Pages.

Alongside the self-hosted HTML5 build of Run 3, you will find a curated lineup of top-tier gravity runners, 3D tunnel sprints, and parkour platformers. Every single game features a custom write-up, detailed control breakdowns, and genuine gameplay tips.

How the games work

Run 3 itself is the HTML5 build of the game, hosted on this domain and running in your browser. Its save file lives in your browser’s storage, which is why a career carries on between visits on the same device. The other games are HTML5 builds embedded from the game host that serves our sites. Nothing is installed, no account is needed, and a game only starts downloading when you press Play.

Who writes the content

The descriptions, control guides, tips and answers on this site are written by the people who run it, after playing the games. Where we describe a mechanic, it is because we have used it. If something we have written is wrong, tell us through the contact page and we will fix it.
