We call it Skat but, I see from Wikipedia that it is altogether a different game. odd.

Skat
Skat is a game for exactly three players. At the beginning of each deal, one player becomes declarer and the other two players become the defending team. The two defenders are not allowed to communicate in any way except by their choice of cards to play. The game can also be played in a round of four players; in this case, the dealer will sit out the hand that was dealt.

A central aspect of the game are the three coexisting varieties called “suit game”, “Grand” and “Null”, that are differing in suit order, scoring and even overall goal to achieve.

Each deal starts with a bidding phase to determine declarer and type of game. Then, ten tricks are played, allowing players to take trick points: each card has a face value (except in Null games) and is worth that amount in points for the player winning the trick. The total face value of all cards being 120 points, declarer's goal is to take at least 61 points in tricks in order to win the deal. Otherwise, the defending team wins the deal. Points from tricks are not directly added to the players' overall score, they are only used to determine the outcome of the deal (win or loss for declarer), although winning by certain margins may increase the score for that deal.

After each deal a score is awarded, depending on the type of deal, how high it was won (or lost) and bidding calls that had been made. Generally, if declarer wins he or she scores a positive amount, otherwise the score is doubled and subtracted from declarer's tally (i.e. a negative score).
