Klaverjas
ENG
A score keeper for Klaverjas

Cards on the table, score on the phone.

Klaverjas is the most popular card game of the Netherlands and Flanders: four players in two teams, a trump, roem in the tricks and nat for a playing side that fails to score more. This app takes the place of the pencil and paper: it knows who deals, counts the roem, sees nat and keeps the score to the end.

At the table

Everything you used to scribble in the margin

The app knows the rules of Klaverjas, so all that’s left at the table is to play and call out the points.

  • Two teams of two

    Four players, partners sitting opposite. Use your own names or just “Us” and “Them”.

  • Who plays

    Mark who chose the trump and the app checks whether that side scored more than its opponents, roem included.

  • Nat

    Didn’t score more? That’s NAT — the opponents get the 162 and all the roem of the deal. Equal points are nat too.

  • Every roem and pit

    Three and four in a row, four of a kind, four jacks, stuk and pit, counted with “−” and “+”. Enter one side’s points and the app gives the rest of the deal to the other.

  • To 1500

    The game runs to 1500 points: the first side to reach them wins.

  • Rules to hand

    The rules of Klaverjas are built in — in all seven of the app’s languages, no internet needed. Or read them in advance right here.
