The Yatzy Protocol app is free to use and have an in-app purchase to get a "Premium" version that goes beyond being just a protocol for a single device.
- Free version
The app started up as a totally free app with the functionality of being a Yatzy/Yahtzee/MaxiYatzy protocol that required physical dice to play.
Being a fully functional protocol for a single device has always been free and will always be free. The app as a protocol is in no way restricted just because an in-app purchase for additional functionality has been added.
- Premium version
The Premium version basically adds two things to the app:
- The ability to share protocol among up to 6 devices connected to the same WiFi network.
- The ability to have in-app dice play where you don't need physical dice to play.
