Aurum

Aurum is a trick-taking game for three or four players, with two teams of two competing in the four-player game. After all cards for the round have been dealt, you bid on how many tricks you think you/your team will win. (In a four-player game, the higher of the two bids on a team becomes the team's bid.)

During the round, you can lead with any non-gold card. On your turn, you must not play a suit that has already been played (unless it is a gold card). The highest number played wins, but gold is the trump suit and always wins. Whoever played the lowest non-gold card adds a gold card of the same number from the supply to their collection if it is available. All gold cards played in a trick are returned to the supply.

The round ends immediately when a player cannot play a valid base metal card and does not have a gold card to play or chooses not to play a gold card. If you win more tricks than you bid, you earn your bid value as points; if you met your bid exactly, you earn twice your bid value as points. Additionally, you earn points for the number of gold cards in your collection. The player/team with the most points wins a gold nugget, and the first to collect two nuggets wins!
