Frequently asked questions

01 Is Brain Test X: Hard Challenge free?

Yes. Brain Test X: Hard Challenge is listed as free on Google Play and offers in-app purchases ($0.99 - $24.99 per item); it also shows ads.

02 Which Android version does Brain Test X: Hard Challenge need?

The current release requires Android 7.0. If your device is older, one of the 9 earlier versions listed above may still install.

03 How do I install the APK?

Download the file from the version page, open it on your Android device and allow installs from this source when prompted. XAPK bundles need the APKPure app or a split-APK installer (see the install guide in the footer). Always prefer the latest version unless you specifically need an older build.

04 Is the download safe?
