According to the oldest known French rules of 1637 Tarock (or "tarot" in French) was a trick-taking card game for three players using 78 cards of designated values, the players vying with each other to score as many points as possible. In its heyday from about 1730 to 1830 Tarock was played with this rule framework across a large part of Europe. In addition, variants were developed for four players with two teams of two – usually similar in principle to the game of Troccas that is still widespread today in Grisons.
