About SyphonGames

SyphonGames is a free HTML5 games portal built in Australia. One idea runs through the whole thing: a game should start the moment you want to play it.

Why the site exists

Browser games used to be the easiest thing on the internet. Somewhere along the way they picked up launchers, accounts, newsletters and consent walls. We stripped all of that back out. Click a card, the game loads in an iframe, you play. There is nothing to sign up for and nothing to install.

How it works

Every game here is a self-contained HTML5 bundle. Developers or our team upload the game as a ZIP, the server checks the contents, extracts it into its own folder, and serves it from a path of its own. Your browser does the rest. There is no plugin, no Flash emulator, and no server-side game logic.

• Sandboxed. Each game runs in a locked-down iframe. It cannot reach the rest of the site or read anything outside its own storage.
• Checked before it lands. Uploads are validated for structure, file types, and size before a single byte is written to disk.
• Sorted automatically. New games are matched against the category keyword lists, then reviewed by hand.
• Nothing loads until you ask. Game pages hold the iframe back until you press play, so browsing does not eat your data.

Where the games come from

Every game on the site right now was made in-house by SyphonGames — designed, built and published by us. That is the whole library as it stands today.

We also host games by independent developers, and the library will grow that way. When we do, the rules are simple: the developer keeps their game. Their copyright, their code, their art. Hosting a game here does not hand us ownership of it, and any developer can ask us to take theirs down at any time, for any reason, without explaining themselves.

Developers who would rather not be named can say so, and their game is published under the SyphonGames name instead of theirs. That is a credit line, not a transfer — an anonymous game still belongs to whoever made it.

Submitting a game

We take HTML5 bundles that run without a server. Package the whole game as a ZIP with index.html at the top level, keep every path relative, and make sure it works when opened from a plain folder. If it needs an API key, a backend, or a specific domain, it will not run here.

• ZIP under 200 MB, with an index.html entry point
• Relative paths only, no absolute URLs to your own host
• A 480×270 cover image helps, though we will generate one if you skip it
• No trackers, no ads injected into the bundle, no cryptominers

Ready to send one? Send it through the contact form — tell us your name (or that you would rather stay anonymous), where the game lives, and how you want to be credited.

Getting in touch

Takedown requests, submissions, bug reports and complaints all go to the same place: our contact form. Takedowns are actioned first.

If a game is broken, tell us which browser and device you were on. "It doesn't work" is true of everything at some point and helps us find nothing.
