Made for the table, not for the screen.

Four people, one phone in hand, dim light. The board has to be readable at a glance and usable with a thumb. Everything else is a side dish.

  • One motion per round

    Slide to one side's points and the other side gets the rest of 157. Trump, weis and match are one tap each.

  • Live on every phone

    One link and everyone at the table sees the same score. Anyone with the link can write – no arguing over who holds the board.

  • Watch mode for the table

    Put a tablet or laptop in the middle: two big numbers, the trump maker, the last rounds. No buttons, nothing to knock.

  • Stats and timeline

    Every round in the log, the game as a curve, and per player: win rate, points as trump maker, weis and matches – across all games.

  • Your colours, your rules

    Ecken, Herz, Schaufel, Kreuz, Obeabe, Undeufe, Slalom – each with its own multiplier. Weis values, target score and icon colours are set once.

  • Works offline

    In the mountain hut with no signal the board keeps going. Once you are back online it syncs – nothing is lost.

  • Web app today, apps soon

    Runs in any browser and installs to the home screen. Native apps for iOS and Android are coming.

  • Free

    No ads, no tracking, no subscription. A side project from Switzerland for people who play Jass.

The score, big enough for the whole table.

Watch mode shows only what counts. Score changes count up briefly, the trump cross-fades – nothing else moves.
