Four players get 13 cards each. Be the first to get rid of all your cards.
3 < 4 < 5 < 6 < 7 < 8 < 9 < 10 < J < Q < K < A < 2
Suits break ties: ♣ < ♦ < ♥ < ♠. The 2♠ is the biggest card.
A plain flush and a bare three of a kind aren't allowed.
Whoever holds the 3♣ leads first, and that play must include the 3♣. Play moves counter-clockwise. On your turn, either beat the last play with the same kind of play (pair on pair, five-card hand on five-card hand) or pass. Passing doesn't lock you out of the trick. Once the other three pass in a row, the last player to play starts a new trick with anything they like.
Bombs: a Four of a Kind or a Straight Flush also beats any single or pair.
The round ends as soon as one player runs out of cards. Everyone else pays 1 point per card left. That doubles if you have 10 or more cards left, and triples if you still have all 13. The winner collects the total.
