How to submit your browser game to SlowDen (2026 walkthrough)

SlowDen lists browser-playable games — things a player opens in a browser tab, with nothing to install. Before you spend time on the rest of this guide, check your game against four things:

• It runs in a browser. An HTML5 or web build. If a player needs to download an installer or an app, it isn't a browser game in the SlowDen sense.
• It's playable, not a trailer. A tiny finished loop beats a big unfinished idea. One screen is completely fine.
• It behaves on a phone. A lot of browser-game players are on mobile. It doesn't have to be mobile-first, but it shouldn't be unplayable there.
• It's yours to share. You made it, or you have the rights to put it on a public site. Free assets are fine — credit them.

You do not need to be a studio, and you don't need a portfolio. First-timers and students are genuinely the target here.

Any engine that exports to the web works. If you're on Godot, that's the Web export preset; GDevelop and Construct both export to HTML5 directly; Unity uses WebGL; and if you wrote it in Phaser or plain JavaScript, you already have one.

Two things worth doing while you're in the export screen, because they're annoying to fix later:

• Keep the build small. Browser players bounce on a long loading bar. Compress textures and audio; drop the sample you're not using.
• Don't rely on the page around your game. Your build may end up inside an embedded frame. If your controls or instructions live in HTML outside the game canvas, put them inside the game too.

You host your own game, and you send SlowDen the link. That's deliberate — it means you keep control of the build and can update or pull it whenever you like.

Three free places that work well for this:

• itch.io — the default for indie web games. Free, gives you a page with a description and screenshots, and handles the embed for you.
• Netlify — drag your exported folder onto the drop area and you get a live URL. Good if you just want the game, no storefront page.
• GitHub Pages — free hosting straight from a repo. Nice if your project is already on GitHub.

This is the step people skip, and it's the one that quietly kills submissions. A link that works on your machine, in your browser, with your cache, is not proof of anything.

1. Open your link in a private/incognito window. If it needs a login to view, it isn't public yet.
2. Open it on an actual phone. Check the game fits the screen and that you can control it by touch — or that it clearly says it's keyboard-only.
3. Watch the first ten seconds. Does it load, or does it sit on a blank screen? Does a new player know what to press?
4. Check it survives being embedded. Games on SlowDen run in a sandboxed browser window, so if your game breaks inside an iframe, it'll break for players too.

Have these ready in a single note before you submit. It turns the last step into a two-minute job:

• Game title — spelled exactly how you want it displayed.
• Play link — the public URL from step 2.
• Your creator credit — the name or handle you want on it. This is your byline; spell it your way.
• A one-line description — what the game is and how to play, in plain words.
• Genre — puzzle, arcade, racing, .io, whatever fits.
• Asset credits — anything you used that someone else made.

Updated 31 July 2026. There are now two separate submission routes, and you only need one of them:

• A finished game, no challenge involved. This is most people. Use the general submission form on the submit your game page — game name, playable link, a short description, your engine, your email, and a tick to confirm you have the rights to it. It does not matter when you made the game or what you made it for.
• An entry for a Slow Cook challenge. Slow Cook is SlowDen's ongoing browser-game challenge, five prompts on the menu at a time, a round running about a month. If you built for one of the prompts, use the Slow Cook entry form so it is read as an entry rather than a general listing.

Both are free, both are read by a person, and neither publishes anything automatically. Check the Slow Cook page for the current five prompts and the round's close date before you build for a challenge — the menu is changed from time to time, and it was replaced on 31 July 2026.

The full official rundown, including the FAQ on ownership and fees, lives on the submit your game page — that's the page to check first, and the one to bookmark.

Here's the part a lot of platforms are vague about, so we'll be blunt:

• It's free. No fee to submit, no fee to be listed, no revenue share to sign.
• You keep your game. It stays yours, and you can have it removed at any time.
• Games run in the browser. Games run in a sandboxed browser window — nothing is downloaded onto anyone's device. Update, 31 July 2026: the partner catalogue is temporarily paused while SlowDen completes its publisher registration, so partner games will not start until that is done. Submissions are still open.
• Selected winners get a chance to be featured on the SlowDen homepage, plus a shoutout across SlowDen's social accounts.
• Nothing is guaranteed. There is no guaranteed traffic, no guaranteed downloads, no guaranteed revenue, no guaranteed followers and no guaranteed feature. SlowDen is a place to be discovered, and that's the honest size of the offer.

If a platform ever promises you players, treat that as a red flag. Nobody can promise you players.

So you know exactly what you'd be joining: SlowDen lists games from a mix of sources. Most partner titles are shown in partnership with Playgama and remain © their respective studios. Games SlowDen makes itself are marked as SlowDen Originals. A game you submit is a creator-submitted game — separate from both, and credited to you.

Export the web build, get it on a public link, open that link on your phone, and pick a prompt. A small finished game that a stranger can reach from one link is worth more than a big one nobody can find.
