For Developers: Submit A Game To Mopoga

Why List A Game Here

Mopoga is a directory, not a platform. We are not trying to become the place your game lives, only the place people find it.

What We Look For

These five standards decide whether a title is listed, and they decide removals later. They are the same ones published on our Editorial Policy page, so nothing here is applied privately.

1. 01It runs in the browserThe game starts inside a normal tab. No install, no app store detour, no companion download. A title that needs a native app to work properly does not belong here.
2. 02It is free to openAnyone can start it without a payment, a trial window or card details. Sell whatever you like inside the game. The door itself is never locked.
3. 03It works on a phoneControls are usable with a thumb on a mid-range handset, not only with a mouse on a large screen. This is where most submissions fail.
4. 04It fits a real categoryTell us where you think it belongs. We will move it if we disagree, because a racing game filed under puzzle wastes a reader's time.
5. 05It stays upA listing that no longer loads is a broken promise to our readers, so it comes down. Tell us before you move or retire a game and we will handle it properly.

Technical Requirements

Nothing exotic, but these are the things that actually stop a submission from working when we test it.

• HTML5, WebGL or WebGPU, served over HTTPS. A page served over plain HTTP will be blocked in a frame on a secure page, which ends the test before it starts.
• Embeddable in a frame. Check that your headers permit it. An X-Frame-Options: DENY or SAMEORIGIN header, or a restrictive Content-Security-Policy: frame-ancestors, will stop the game loading for us and for everyone else who lists it.
• A responsive canvas. The game should fill the space it is given rather than assuming a fixed desktop resolution. State whether it needs portrait, landscape or handles both.
• Touch input handled directly. Not mouse events that happen to fire on tap. Multi-touch, drag and long press should all behave as a player would expect.
• No forced fullscreen and no orientation lock without a way out. Both are reliably infuriating on a phone.
• A first load that finishes. There is no hard cap, but the heavier the initial payload, the more players close the tab before your first frame. Anything with a progress bar measured in tens of megabytes is fighting the whole premise of the site.
• No permission prompts before gameplay. Camera, microphone, location and notification requests all fail our test. Ask after the player has a reason to say yes, if at all.
• No account required to start. Optional sign-in for cloud saves is fine. A wall before the first frame is not.
• Progress saved locally. Local storage or IndexedDB is expected and normal here. Players are told on our guides page that saves live in their own browser.

What To Send

One email with these details is enough. We do not run a submission form, because a form loses everything that does not fit its boxes.

How Submission Works

There is no queue system and no dashboard. A person reads the email and a person plays the game.

1. 01You send one emailTo info.imopoga@gmail.com with Game submission in the subject line, carrying the details above.
2. 02We play itOn a phone and on a desktop browser, in a frame, without an account and without a download, against the five standards above.
3. 03You get an answer either wayIncluding when the answer is no. If it failed on something fixable, we will say what it was, because a fixed build is welcome back.
4. 04The listing goes liveWith your title, your description, your developer credit and a link to you. We will send you the URL so you can check we have described it fairly.
5. 05We tell you when something breaksIf the game stops loading we contact you before pulling the listing, wherever we have a working address for you.

What We Turn Down

Most rejections are one of these, and none of them are a judgement on the game itself. Several are simply the wrong site.

• Anything that requires an install, including a download presented as optional but needed to play properly.
• A paywall, trial timer or card requirement before the first frame.
• Desktop-only controls with no touch scheme at all.
• An account wall before gameplay, including a forced social login.
• Games you do not have the right to submit. We check, and a false claim of ownership ends any further dealing with us.
• Misleading advertising inside the build, particularly fake system warnings, fake download prompts or adverts dressed as gameplay.
• Adult content, and anything a general audience site with a Kids category cannot reasonably carry.
• Pages that hijack the browser, break the back button, open pop-unders or redirect away from the game.

After You Are Listed

A listing is not a contract and you are not locked into anything. Here is what you can ask of us afterwards.

If you believe we have described your game unfairly or filed it in the wrong place, write and say so. We re-test rather than defend the original write-up, and you have a right of reply either way. Copyright matters follow the separate process on our DMCA Policy page.

Questions Developers Ask

• Does it cost anything to be listed?

  No. There is no listing fee, no placement fee and no revenue share taken from your game. Whatever advertising or in-game purchases you have built in stay yours.

• Do you host my files or embed my link?

  We embed. The build stays on your servers, which means you keep control of updates, analytics and anything else that runs inside it. It also means your headers have to permit framing.

• Do you want exclusivity?

  No. List the same game anywhere else you like, before or after us. A directory that demanded exclusivity would be a worse directory.

• Can I submit a game I did not make?

  Only if you hold the rights to it or are acting for whoever does. We ask who owns it for exactly this reason, and we act quickly on ownership complaints.

• Will you list a game that is still in development?

  It has to be playable start to finish in a browser today. An early build that meets the standards is fine; a demo that ends on a wishlist prompt is not.

• Can I pay for a better position or a feature?

  No. Placement is not for sale. Sponsored content exists on the site, is labelled as sponsored, and does not change what is listed or where.

• What happens if my game is down temporarily?

  Tell us and we will hold the listing. We only remove what appears to have gone for good, and we try to reach you first.

Send Your Game

One email, the details above, and a link that plays. Support is staffed 24 hours a day and submissions are read by the same small team that runs the library.
