Samschtig Jass

"The popular Differenzler Jass, as played on the Samschtig Jass programme, is now available on CD-ROM. The product has been developed in collaboration with Swiss television DRS and the creators of the popular Schieber Jass programme Stöck Wyys Stich.

With the Samschtig Jass CD, Differenzler can be played alone or via a network (including the internet) with up to four partners. The playing strength of the individual computer players and all standard Jass rules can be customised. The software plays with German or French cards. Samschtig Jass is suitable for beginners and advanced players alike: the tip guide helps you learn Differenzler by advising you on bidding and playing the right card."
