Each round, every player gets a hand of 8 cards, ranging from 1 to 50. Now the player has to predict how many points his tricks in this round will be worth. A range can be selected (with some restrictions) - narrow ranges will yield more game points (hearts) than higher ones, if successful.
Then the tricks are played out. Beginning with the player who collected the last trick, everybody plays a card. The highest numbered card wins the trick. Trick points are the number of goat heads on each card (1-5), *plus* the card number of the lowest card in the trick.
At the end of the round, all players who predicted a correct gain game points (2-5, depending on the range selected).
The game ends after several rounds (depending on player number). The player with the most game points wins.
