SlowDen is a free browser-game site, and any developer can submit a finished browser game to it at no cost. Made one? Send the link and get it played online — no downloads for players, no fees for you. You do not need to enter a challenge: any finished, playable browser game is welcome.
Building for a challenge instead? Slow Cook is SlowDen's ongoing browser-game challenge — five prompts on the menu, closing 1 October 2026. Challenge entries go through their own form so they are judged as entries.
Nothing finished yet? That is the usual reason a submission never happens. Start with how to finish a game in one month — scoping a game small enough to actually ship is a separate skill from building it, and it is the one worth learning first.
Worth reading before you send anything: your game will run inside an <iframe> here, and plenty of games that work perfectly on their own page break the moment they are embedded. Why your game breaks inside an iframe covers the five that actually bite — fullscreen being off until the host grants it, storage that is missing or not the storage you think, audio that will not autoplay, the keyboard going to the host page instead of your game, and a frame that is not the size you designed for. Checking it first saves a round trip.
Yes. Submitting a browser game to SlowDen is completely free — there are no fees and no catch.
No. There are two separate routes. Use the general form for any finished browser game, whenever you made it and whatever you made it for. Use the Slow Cook form only if you built something for one of the current challenge prompts and want it read as a challenge entry.
Browser-playable games (HTML5 / web games) that you host yourself — for example on itch.io, Netlify or GitHub Pages. You submit a link, and the game runs in the player’s browser with nothing to download.
Yes. Your game stays yours. SlowDen lists it so people can play it, and you can ask for your own game to be removed at any time.
Fill in the general submission form on this page with your game name, a link to where it is playable, a short description and your email, and confirm you have the rights to it. Every submission is reviewed by a person, and games have a chance to be listed or featured.
No. SlowDen is a place to share your game and be discovered, and selected games can be featured plus get a social shoutout — but there are no guaranteed views, downloads, revenue or placements.
Notes from building and running SlowDen — all measured on real pages, not advice written from memory.
If your game is on SlowDen, you are welcome to link to its page from your own site or itch.io page. Swap YOUR-GAME-SLUG for the last part of your game’s SlowDen URL.

No tracking and no obligation — use it if it is useful to your players. Full badge kit and press facts are on the press page.
Drop in your link and send it over. Every submission is read by a person.
