Questions before you download
Are the apps free?
All four apps were listed as free to download in the US App Store on 5 October 2026. They include advertising and optional in-app purchases. Availability and local prices can change; check the App Store listing before downloading.
Can I play offline?
Core play works offline in these apps. Advertising, purchases, restoring purchases and other online services need an internet connection. The App Store listing describes the features of the current release.
Does browser progress transfer to the app?
Browser and app progress are stored separately on their respective devices. There is no account-based synchronisation, so downloading the app does not import a browser save.
How do I get help?
Email support@goofergames.com with the app name, version and a description of the issue. Do not include passwords or payment details. Apple handles App Store payments.
