For developers
A CrazyGames alternative that publishes your game today
CrazyGames is a good place if you pass their review. If your game was rejected, is waiting for Basic Launch or got few players, you have a second road: upload the HTML5 package to klyo and the game gets its own address and a page in Google the same day.
Why CrazyGames rejects games
Their quality guidelines say what they expect: a simple onboarding you can skip, a clear goal, controls shown on screen, high-resolution graphics without artifacts, consistent audio and a name that cannot be confused with another game. From their FAQ: QA rejects games for bugs, unoriginal content and policy violations, and an improved game can be resubmitted.
These are fair criteria, but they work as a filter: a game that did not pass has nowhere to stand. The developer is left with a finished package and no address to send anyone.
How it works at CrazyGames (their FAQ, 17 September 2026)
After review the game first enters Basic Launch: a small group of players sees it and ads are off, to measure engagement. If the numbers hold, the game passes a second review and goes to Full Launch with ads. Payouts are monthly from €100 by wire or PayPal. No exclusivity is required and the rights stay with you. The ad revenue share is not published in the docs.
How klyo games differs
There is no review queue. A machine checks the package for malicious code and third-party ad networks, nothing else. The game gets its own subdomain g-yourgame.klyo.pl right away and a catalogue page in English and Polish that Google can index. You add Google Play and App Store badges to the page if the game is also an app.
The ad share is the same for everyone and printed in the terms: 70% of net ad revenue on your game, paid by bank transfer from 100 PLN. To be clear: ads next to games are not switched on yet (as of September 2026), so the share starts counting from the first day they run. There is no exclusivity and never will be: you can have the game on CrazyGames and on klyo at the same time.
If the game already runs somewhere, you do not repackage it: paste the address, we fetch the files and put a copy under its own address.
A large game from Godot or Unity
According to the CrazyGames technical requirements (16 October 2026), the whole game fits in 250 MB and the initial download in 50 MB, or 20 MB to appear on their mobile homepage. Those are sensible limits for games that should start in a second, but a 3D game exported from Godot or Unity often goes past them.
On klyo the ZIP can be 350 MB, 700 MB unpacked and 500 MB for a single file. Players download the engine and game data (.wasm, .pck, .data) from our CDN, with no change to the game code. A game made only for mouse and keyboard can be marked as a computer game, so it does not show up on phones.

CrazyGames and itch.io data from their own developer pages: CrazyGames FAQ, CrazyGames technical requirements, itch.io creators FAQ, itch.io HTML5. Terms checked on 17 September 2026, size limits on 16 October 2026; the current numbers are always on their pages. If anything changed, tell us and we will fix it.
Can I publish on CrazyGames and on klyo at the same time?
Yes. Neither side requires exclusivity: CrazyGames says so in its FAQ, we say so in the developer terms.
Does someone review my game before it goes live on klyo?
No. An automatic check looks for malicious code and third-party ads. Whether the game is good is decided by players, not a reviewer.
When do I start earning?
The 70% share is written in the terms, but ads next to games are not switched on yet. When they run, they count from day one and payouts go by bank transfer from 100 PLN.
What about a game CrazyGames rejected?
Upload the same HTML5 package to klyo. If it passes the automatic check, it has an address and a page the same day. You can improve it in parallel and resubmit to CrazyGames.
