Publish your HTML5 game and earn from ads

On klyo games: drop the game as a ZIP, a folder or a single HTML file, the game gets its own address g-yourgame.klyo.pl and a catalogue page, and you get 70% of the net ad revenue attributed to your game. No application, no exclusivity, the rights stay yours.

70% of the net Google ad revenue attributed to your game, counted by plays. The monthly pool is split between games in proportion to plays. Payout by bank transfer from 100 PLN (about 23 EUR).

CrazyGames requires an application and a manual review that takes weeks, and does not publish its revenue share. Here publishing is instant after an automatic check, the share is printed on this page, every game has its own subdomain and there is no exclusivity.

itch.io does not pay ad revenue for HTML5 games; you only earn from sales. Here a free browser game earns from the ads next to it from day one, and you get leaderboards and cloud saves without running a server.

Yes. We do not ask for exclusivity and do not block publishing the same game anywhere else. You upload the same ZIP.

Anything that exports to files that run in a browser: Godot, Unity WebGL, Construct, GDevelop, Phaser, PICO-8, Defold or hand-written code. The one condition: after unpacking, the game opens from index.html.

Yes. Every game runs on its own subdomain, g-yourgame.klyo.pl, isolated from other games and from klyo cookies. You can use it as the game's address anywhere.

Yes, in a single field. Wrap each version in a language tag: <pl>polski opis</pl><en>English description</en>, and players see the one in their language. Square brackets work too: [pl]…[/pl]. Without tags the description stays in one language, and that is fine: we show it everywhere, we only mark its real language so a page in another language does not pass a foreign sentence off as its own.

Because it is not the same as the language of the description. The description is read BEFORE playing; the menus and text inside the game are read WHILE playing. Players can set which languages they want to see, and your answer decides who your game is shown to. The strongest answer is “there is not a single word in the game”: numbers, shapes and icons only, like 2048 or a block puzzle. Such a game suits everyone and we show it to everyone, whatever their setting. No large game catalogue states this, even though every player has bounced off a game with menus in an alphabet they cannot read.

Yes. If you build the game with Claude or ChatGPT, the assistant can send the package and prepare the entry, and you only look at the finished game and release it to the catalogue with one button. The assistant does not sign the agreement and does not put the game in front of players: both steps are yours. How to connect it is described on the page “Publish with an assistant”.

Not always. Google ads are not shown everywhere: since 2022 Google has not sold ads to audiences in Russia, and in embargoed countries it does not operate at all. A player from there will start your game and nobody blocks them, but that round brings no revenue. Payouts are a separate matter: the transfer leaves a Polish bank, so we cannot send money where European Union sanctions forbid it, today including Russia and Belarus. You can publish a game from anywhere in the world; the details are in the developer terms, in the sections on ads and on payouts.

We close a month by the 15th of the next one and pay by bank transfer once your balance reaches 100 PLN. Developers outside Poland provide a tax residency certificate so the double-taxation treaty applies; EU businesses invoice with reverse-charge VAT.
