How to Compare Free HTML5 Game Catalog Providers Before Embedding

Choosing where your games come from is a bigger decision than choosing which games to show. The provider decides what you may display, who earns from the ads, how quickly you must remove a game, and whether your pages keep working when a game is updated. This guide gives you a checklist for comparing providers and applies it to three of them.

Disclosure: BlogKovo is part of the Kovo family, which includes PlayKovo. We include PlayKovo in the comparison because we know it best, and we say plainly where it is weaker than the alternatives.

The eight things worth checking

1. Revenue terms. Does the provider pay site owners, and on what basis? "No revenue share" is a legitimate answer as long as it is stated.
2. Embed method. An iframe, a script widget, a JSON or XML feed, a white-label portal? Each has different design freedom.
3. Per-game device and orientation data. If the provider tells you which games work on phones, you can filter before you build a page.
4. Hosting and updates. Are games served from the provider, so fixes reach your site automatically?
5. Ad behaviour. Who controls the ads inside the game, and can you change them?
6. Removal process. How quickly must you take a game down when asked, and how will you find out?
7. Barrier to start. Do you need an account and an approval before you can copy a single embed?
8. Catalog depth. A bigger catalog is more choice, but only if the games are usable on your site.

What we could verify

The facts below come from the providers' own public pages (or PlayKovo's live feed) read on 13 October 2026. Marketing pages rarely tell the whole story, so a blank here means "not stated on the pages we read", not "the provider does not do it".

Sources: the Playgama Partners page, the GameMonetize publishers page, the PlayKovo embed feed and PlayKovo's Partner Terms (September 2026 version).

We also tried to read the publisher pages of GameDistribution and GamePix. Neither page loaded for us, so we have not scored them. If you are considering them, run the same eight checks from their own documentation.

To see what PlayKovo's per-game data looks like in practice (device badges, orientation and a ready iframe), here is one game running from the same feed the comparison above describes.

A scoring grid you can reuse

Score each check 2 if the provider states it clearly on its own page, 1 if it is partly stated, and 0 if you could not find it. For "revenue", score 2 when the provider offers a revenue share and 0 when it does not. For "barrier to start", score 2 when no account is needed.

Read that table with care.

• It measures how much we could verify, not how good the product is. PlayKovo scores well because its terms and feed were fully readable to us. We read two marketing pages for each of the others.
• Revenue changes everything for some publishers. If earning from your traffic is the main goal, count that row four times. The totals become PlayKovo 14, Playgama 13, GameMonetize 10, and the argument for a revenue-sharing provider gets much stronger.
• Size is not scored. A 50,000-game library is not automatically better for a small site. You will use 10 to 30 games.

How to decide

Match the provider to your goal.

• You want engagement, simplicity and fast removal rules. A small, clearly documented catalog with a plain iframe suits editorial sites that do not want to manage monetization. PlayKovo fits here, with the trade-off that it pays nothing today.
• You want to earn from game ads. Put revenue first and compare payout terms, minimum thresholds and ad control directly with each provider. Playgama and GameMonetize both publish a percentage.
• You want your own design. Prefer a provider with a feed. You can then build your own pages instead of living inside a widget.

Questions to ask any provider before you sign up

• Where are the full terms, and when were they last updated?
• Which games may I embed, and who decides?
• Can I hide or change the ads inside a game?
• What happens to my pages when a game is removed?
• Can I be notified, or do I have to poll a feed?
• Do I need to keep a credit line or logo visible?

If a provider cannot answer those in writing, the rest of the comparison does not matter.

The short version

Do not pick a provider on library size or on the revenue figure alone. Fill in the grid, weigh the rows that matter to your site, and keep a copy of the terms you agreed to. Terms change, and the date you read them is part of your records.
