Rules
The entire deck is dealt out among the players as far as they can go, with an equal number of cards for each player. If there are leftover cards, they are given to the player holding the diamond 3. Joker cards are not used.
At the beginning of each game, the player with the diamond 3 starts by playing it singly or as part of a combination. Play proceeds; each player must play a higher card or combination than the one before, with the same number of cards. Players may pass their turn, meaning that they do not want to play, or do not have the cards to make a play.
When all but one of the players have passed in succession, the turn is over. A new turn is started with all players, initiated by the last player to play.
The game ends when one player runs out of cards.
Examples of valid combinations by number of cards, the five-card combinations ranked from strongest to weakest with the rank determined by the fully-visible card
Combinations
Cards may be played as singles or in groups of 2, 3 or 5. The leading card(s) to a trick sets down the number of cards to be played; all the cards of a trick must contain the same number of cards. The highest ranking card is 2. The combinations and their rankings are as follows:
Singles: Any card from the deck, ordered by rank with suit being the tie-breaker.
Pairs: Any two cards of matching rank, ordered as with singular cards by the card of the higher suit.
Triples: Three equal ranked cards.
Five-card hands: There are five different valid five-card hands, ranking from low to high as follows:
Straight: Any 5 cards in a sequence, but not all of the same suit. Rank is determined by the value of the highest card. The suit is a tie-breaker.
Flush: Any 5 cards of the same suit, but not in a sequence. Rank is determined by the suit of the flush. The value of the highest card is used to break ties.
Full house: a three-of-a-kind and a pair. Rank is determined by the value of the triple.
Four-of-a-kind + one card: Any set of 4 cards of the same rank, plus any card. Rank is determined by the value of the 4 cards.
Straight flush: Five cards in sequence in the same suit. Ranked the same as straights, suit being a tie-breaker.
Scoring
The most common version of scoring is as follows.
For each player with cards, 1 card is 1 point, except if they have 10 or more cards, in which case 1 card is 2 points. The points are paid to the winner. For example, if North wins, and East, West, and South respectively still had 3, 11, and 8 cards left, then East scores −3, West scores −22, South scores −8, and North scores +33.
Any unused 2's, four-of-a-kinds, or straight flushes doubles the points paid to the winner. If the winner ends the game by discarding a 2, a four-of-a-kind, or a straight flush, points will also be doubled. For example: if North wins with a 2 as a last discard; East, West, and South respectively still had 3, 9, and 8 cards left; West had an unused Straight Flush; and South had an unused 2, then East would score −6, West would score −36, South would score −32, and North would score +74.
