Jass Board
The Jass Board app lets you keep score for different versions of Jass directly on your Android smartphone or tablet.
Whether you’re playing Schieber, Coiffeur, Differenzler, Molotov, or other Jass variations, this digital board helps you record points quickly and clearly.
Profiles and Data Management
• You can create multiple profiles, each storing its own settings and scores.
• Unfinished games don’t need to be deleted—simply switch to another profile to begin a new match.
• Different groups or rule variations can each have their own profile for convenience.
• Profiles can be transferred easily using Android Beam (NFC):
+ Open the board on one device, hold the two devices back-to-back, and the data will be shared.
+ This feature is handy if a battery runs out or when you want to copy complex settings to another phone or tablet.

Q: What’s the benefit of using profiles in the app?
A: Profiles help keep your games and settings organized. You can create separate profiles for different friend groups, rule variations, or types of Jass. Each profile stores its own scores, preferences, and ongoing games so you can easily switch between them.
