Here's a good one for you. We call it "Carre Coupe". It's a game for two couples so you'll need an extra hand for two tables. Rules: The game starts by each couple to set a secret code so they'll be able to speak during the game. That's because they can't see each other cards. The aim of the game is to create a foursome of the same card rank in one of the partner's hands and to prevent from the other couple to set it's own foursome. At the beginning each player gets 4 cards. The rest stay in the fund. On each round 4 cards are taken out from the fund and put face up on the table. A player may switch cards with these on the table, though he may not hold more than 4 cards. A player will try to hint his partner on his cards or on the rivals cards using the secret code. When all the players have no more intrest in the 4 cards on the table, the cards are taken out of the game. So obivously, One cannot create a foursome with these cards ranks. The game ends when a player recognizes his body has a foursome and declares "Carre" or when a player thinks the rival couple have a foursome and declares "Couppe" before they declare "Carre". You set points - 1 for "Carre, 4 for "Double Carre",a pair may intentionally choose to wait until each pair member will have a foursome. You should declare "double Carre". 2 points for "Couppe" and  1 point for the other pair for a wrong "Couppe".  "Double Couppe" and  "Double Carre Couppe" are very rare and should get many points. That's it. Reply if something is misunderstood.
