Android blocks installs from outside the Play Store until you allow it. When prompted, tap
Settings → Allow from this source, then open the
downloaded file again. You may also see a Play Protect warning — tap Install anyway.
This is normal for apps installed outside the store.
iPhone & iPad
Apple does not allow betting apps to be installed from a file, so Tafbet installs straight from Safari instead — it still gets its own icon and opens full screen.
Open taf.bet in Safari. This will not work in Chrome or Firefox on iPhone.
Tap the Share button
at the bottom of the screen (or top-right on iPad).
Scroll down and tap Add to Home Screen.
Tap Add in the top-right corner.
The Tafbet icon appears on your home screen and opens without the browser bar.
