Hot to Play Spitzen-Trumpf? // Spielregeln?

You divide the cards up under the players, one starts calling a technical data point (horse power/ps for example) then he tells his cards value and the enemies do the same, the one with the highest value gets all the cards from this round and they put them at the end of their card pile. Then the winner continues calling the next data point. You usual play until one player has all cards
