About
15combo is a browser game portal. Games open in a tab and start right away — no download, no store account, no console.
What this site is
A catalogue of HTML5 games built by partner studios, playable directly in the browser. You pick a game, press play, and it loads in the page — the same way a video does.
How accounts work
The first time you visit, a guest account is created and tied to this browser. You can keep playing that way indefinitely, or attach an email and password later so the same account follows you to other devices. Your player ID identifies the account when you contact support.
Languages and regions
The site is available in English, 日本語, 한국어 and 繁體中文. A few titles are not offered in every region because of the agreement with their publisher; those games stay visible but cannot be started.
For game developers
Games are supplied by partner studios and integrate through our SDK for accounts, payments and cloud saves. If you build HTML5 games and want to publish here, get in touch through support.
