Tarnib 0.0.1

The game
The aim of tarneeb is to win a set of continuous hands. There are four players in partnerships of two teams. A standard 52 card deck is used, each suit ranking in the usual way from Ace (high) down to two (low). The game is played in a counterclockwise fashion. The teams stay together for all the games of a set. In tarneeb tournament, at the end of a set, the losing team is replaced for the next set.

The two members of each team are seated across each other, often on a table in such a way that no player can see the cards of other players (see seating charting image). Either player of a team may collect the winning tricks.

The first dealer is chosen at random and after each hand the turn to deal passes to the right. The cards are shuffled and cut by the player to the dealer's left, and are all dealt out beginning with player to the dealer's right, one at a time or in groups of thirteen (13), so that everyone has 13 cards.
Bidding

Tarneeb seating arrangement.

The bidding begins with the first player to the right of the dealer and continues counter-clockwise. It consists of a number of tricks seven or above. A bid of more tricks outranks any bid of fewer tricks.

Each person can bid only once, eliminating the option for a player to raise their bid. In addition, the dealer, who bids last, has the option to match, rather than raise the highest bid.
Some players actually use the option of telling your partner how good are you cards i.e., helpful, not helpful at all.
Playing

The objective of the bidding team is to take at least the number of tricks that they bid. The objective of the other team is to hinder the declarer team from reaching their declared bid.

The individual declarer leads to the first trick. Players counterclockwise must follow suit if they can; a player who has no cards of the suit led can play any card. A trick is won by the highest tarneeb (trump) in it, if any. If there are no tarneebs in the trick, the highest card of the suit led wins it. The winner of a trick leads to the next.

Playing exceptions
In some regions, the declarer must start the first trick with his declared tarneeb suit. But in most cases they don't.
Scoring

Once all thirteen tricks are played, the scores of the two sides are calculated by adding the tricks each side has won. If the declarer team meets or exceed the number of bidded tricks, then they get the number of tricks they have, otherwise, they lose the bid number (subtracted from their score) and the opposing team gets the number of tricks they complete. It is possible, therefore, to have a negative score at some point. The set ends when one of the teams reaches thirty-one (31) and the losing team is replaced for the next set.

A team can win a game by bidding for 13 tricks, but they have to declare it at the bidding time by calling for a "game" (بالدق).
