Hearts is easy yeah, remove the 2 of diamonds, everyone gets 17 cards (you can play 4 player without removing a card, everyone gets 13 then). Every heart is worth 1 point, Ace of Spades is worth 7, King of Spades is worth 10, Queen of Spades is worth 13. Points are bad and you get points if you win a trick containing a card that scores points. Pass 3 cards to the right before you start. Play whist with no trumps. If you get all the penalty cards you score -50 instead of 43 ("Jump the moon").
Winner is one on lowest score when loser passes 100 points. Or you win if you get to -100.
When your opponents work out you are attempting to jump the moon it gets exciting.
