Ninety-nine

Ninety-nine is a card game for 2, 3, or 4 players. It is a trick-taking game that can use ordinary Anglo-American playing cards. Ninety-nine was created by David Parlett; his goal was to have a good 3-player trick-taking game with simple rules yet great room for strategy. In ninety-nine, players bid for the number of tricks that they will take; players who gain exactly that number of tricks (no more or less) gain a significant bonus. One unusual feature of ninety-nine is that players bid by discarding three cards.

Rules

Dealing

A round of ninety-nine begins with the deal of a shuffled deck. The two and three player versions of the game use only the 6, 7, 8, 9, 10, J, Q, K, A (ranked from lowest to highest) - note that 6 is the lowest rank, and that the 2 through 5 are not included in the deck. The four-player version of the game uses the entire 52-card deck (in which case the 2 is the lowest rank). Players are dealt the entire deck, one card at a time, with all cards face down. In the two-player version, the cards are dealt to the two players and also to a third pseudo-player called the "dummy". As a result, in the two and three player version players are initially dealt 12 cards, while in the four player version players are initially dealt 13 cards. Players should sort their cards by suit, and by rank inside a suit.

Trump suit is then determined. In the very first round of a game, there are no trumps. After that, the trump suit is determined by the number of players who won the last round: Diamonds if 0, Spades if 1, Hearts if 2, and Clubs if 3. In the four-player version, if all four players win a round, the next round is played with no trumps.

Bidding

Each player then bids on the number of tricks they expect to take. Players bid by discarding any three cards in their hand; each suit is worth a certain number of tricks, and the total number bid by three cards determines the bid using the following code:

Suit	Value	Mnenomic
♣ Clubs	3	Clubs have 3 bumps (top, left, right)
♥ Hearts	2	Hearts have 2 bumps on the top
♠ Spades	1	Spades have 1 point at the top
♦ Diamonds	0	Diamond outline looks like a zero

Thus, if a player discards a club and two diamonds, they have bid 3+0+0=3 tricks.

Normally, these discarded "bid" cards are placed face-down on the table, so that the other players will not know how many tricks that player is trying to take. However, a player who is very confident with his hand can also make two kinds of premium bids, which are made out loud to the other players: a declaration, where the bid cards will be shown face-up, or a revelation, where every one of the player's cards will be placed face up. Only one player can make a premium bid in a round; a revelation outbids a declaration, otherwise the Dealer's left has the highest priority.

In a 2-player game, both live players can declare, but neither player can reveal. Also, in the 2-player game, three cards are arbitrarily chosen from the dummy's hand and set aside as the dummy's bid (neither live player knows what the dummy has "bid").

Trick-Taking

After the bidding has been completed, trick-taking begins. If playing the 2-player version, the "dummy's" cards other than the 3 bidding cards are first placed face-up and sorted by suit.

In 3 and 4 player versions, the player to the dealer's left plays the first hand, and play continues clockwise. In the 2-player version, the non-dealer begins play.

Players must follow suit of the suit led if they can, else they can play any card; they need not beat a card even if they can. If a trump card is played, the highest-ranking trump card wins, else the highest-ranking card of the suit lead wins. The winner of a trick leads the next trick.

In the 2-player version, if a live player leads a trick, then the other live player plays next, and the leading player then can choose any (legal) card from the dummy's hand. If the dummy wins a trick, the live player who last led chooses the dummy's card, the other live player plays next, and the player who last led plays his own hand. Thus, the "dummy" is always first or last to play in the 2-player version.

Scoring a Round

After all the cards have been played, the round is scored. Players earn one point for every trick they won, regardless of any other bonuses (or the lack of them). A player who acquired exactly the number of tricks they bid gains a bonus depending on the number of others who also made their bid.

If only one player succeeded, that player earns 30 points; if two succeeded, each earns 20 points; if three succeeded, each earns 10 points; and if all four succeeded in a 4-player game there is no bonus. A declaration adds 30 points (to the declarer if successful, to the others if not); a revelation is worth 60 points (to the declarer if successful, to the others if not).

Note that in the 3-player game, the maximum score in one round is ninety-nine (hence the name): 9 points for winning all nine tricks, 30 points for bidding 9 tricks and getting them (while no one else got their bid), and 60 points for a revelation.

In the 2-player version, the dummy is considered to have succeeded if the dummy wins fewer tricks than it bid, failed if it wins more tricks than it bid, and declared if it met exactly the number of bid tricks. If both live players declare and neither makes it, the dummy gets 60 points.

Games and Matches

Ninety-nine can be played by simply playing until some player reaches a predetermined total over many rounds (e.g., 200 or 500); the player with the largest score wins. If playing as a 2-player game, the dummy's score is not tracked.

Parlett's recommending system for scoring games and matches is more intricate. He recommends that a game end when a player has reaches 100 points or more; any player who reaches or exceeds 100 points in that round also gains a 100-point game bonus, but they only get the game bonus if they succeed in that round (otherwise, they do not get the game bonus, though they get any other bonuses they are entitled to). A new game then starts. When one or more players wins 3 game bonuses, the totals across all games are totalled, and the player with the highest score wins.

Strategy

A key to playing ninety-nine well is discarding cards wisely to make a bid. In the 2 and 3 handed games, 3 cards must be discarded from 12, resulting in 220 different options. Players must estimate what will happen to each of the cards they retain, and will need to consider important factors such as what suit is trump and who will lead first. Players will often want to get rid of "middle" cards (cards that are neither likely winners nor likely losers), and may want to "void" themselves of a suit (since, once they have no card in a suit, they are free to play any other card if that suit is led).

One of the most common bids is 3, and one of the next most common bids is zero. As a result, diamonds and spades are more likely to be discarded as bid cards than other suits (and thus there will be fewer in play and these suits are less valuable). Conversely, few clubs tend to be discarded, making high clubs likely winners.

If a hand is truly unbiddable (where the cards needed to bid with are also the cards needed for play), one strategy is to discard surprising cards (such as all high cards of a given suit). In this case, the player doesn't intend to make the bid; the player is hoping to make it difficult for anyone else to make their bids.

Often players will want to gain the lead early and play their most uncertain cards first; that way, if they win tricks, they can try to throw away some other strong cards. Conversely, if the uncertain cards lose, they can try to pick up tricks with stronger cards.
