Frequently asked questions
01 Is Number Master: Run and merge free?
Yes. Number Master: Run and merge is listed as free on Google Play and offers in-app purchases ($4.99 - $6.99 per item); it also shows ads.
02 Which Android version does Number Master: Run and merge need?
The current release requires Android 6.0. If your device is older, one of the 20 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?
Files are served by an established third-party mirror and are the same builds distributed to Play Store users; Appmello never repackages or modifies them. Check the developer name (KAYAC Inc.) and package name (com.kayac.level_up_number) match what you expect.
05 How do I get my account back?
Accounts belong to the developer's own service, not to this site. Use the sign-in recovery option inside Number Master: Run and merge, or contact KAYAC Inc. through the support address listed on Google Play.
06 How do I cancel a subscription?
Subscriptions bought through Google Play are managed in the Play Store under Payments and subscriptions; purchases made inside the app follow the developer's own billing.
07 Can I get a refund?
Appmello never charges for downloads, so there is nothing to refund here. Refunds for in-app purchases are handled by Google Play or by the developer. Never enter payment details on any page claiming to be a download step.
08 How do I use Number Master: Run and merge?
Open the app after installing; it works exactly like the Play Store build. For feature questions see the developer's help pages, as Appmello only distributes the installer.
