Game Credits & Open-Source Licenses

How ZGame uses open-source games

When an open-source game is included, ZGame keeps the upstream license information in the distributed source folder and adds its own website integration around the game. Depending on the title, that integration can include responsive framing, touch handling, fullscreen support, account-linked saves, score syncing, leaderboards, page instructions and accessibility or layout fixes.

Important: Open-source software licenses apply to the upstream code as described below. ZGame branding, site copy, account systems, guides and original game code are separate website content. If you believe an attribution is incomplete, please contact us so it can be reviewed.

Why some old game URLs redirect

ZGame periodically removes or retires titles when they are no longer a good fit, are technically obsolete, or need additional rights review. Retired public URLs may redirect to a currently supported alternative so old bookmarks do not lead to broken pages. Retiring a public route does not change historical score records stored for account continuity.
