Jass for Windows with a hand-painted German-Swiss deck

The cards matter. The rest stays out of the way.

01

Playing strength first

Your partner thinks with you. The opponents play well. Not flashy. Just challenging.

02

Straight to the table

The interface stays restrained. Cards, calls, tricks and points appear where an experienced Jass player expects them.

03

A deck with character

Play with a hand-painted German-Swiss deck. Familiar, distinctive and free of visual clutter.

04

Stronger through collaboration

The feedback function lets you report a playing decision directly. Your observation helps the developer to improve the playing strength.

User testimonial

Finally, a Jass game that focuses on what matters.

If you know Schieber or Coiffeur and simply want to enjoy a good game, you’re in the right place. The controls are refreshingly clear, the hand-painted German-Swiss deck has character, and both your partner and your opponents play at a pleasingly challenging level.

I particularly like that this Jass game isn’t overloaded with unnecessary effects or animations. It’s the cards that count, not the trimmings.

It annoys me that I can’t play this game on my iPhone. There, I always have Mrs Häfliger as my partner.

Why this Jass exists.

I wanted a Jass game where my partner and opponents play intelligently. With feedback from experienced Jass players, I keep improving its playing strength.

The story behind the game: “500 hours to create a Jass program” – Schweizer Jassverzeichnis (article in German)

Schieber or Coiffeur.

Two formats, the same priorities: a capable partner, strong opponents and an interface that doesn’t get between you and the game.

Game formats in detailFormats, scoring and built-in playing conventions

Schieber and Coiffeur

    • Opening lead in the first trick with trump
      • Trump Under only: it is not played.
      • Trump Ace (without Under or Nell) and at least one other trump: the highest trump after the Ace is played.
      • Trump Ace only: it is played.
