Gong Zhu
Gong Zhu (拱猪) is a Chinese four-player trick-taking card game, and is a Chinese version of the game Hearts. It differs from the standard Hearts game by assigning special point values to cards. The objective of the game is to score positive points and avoid penalty points. Gong Zhu means: "Chase the Pig", for "pig" is the name given to the Q♠. All players start with 0 points. The goal is to not be the first person to go past -1000 points (thus losing the game) and in some variations, also not more than 1000  points. The loser(s) becomes the pig, as "Gong Zhu" means "chase the pig" in Chinese. All points accumulate until any player(s) have lost, for which the game ends and all points will be reset to 0. Unlike in Western Hearts, there is no passing of cards prior to each round in Gong Zhu. Exposure of cards. In Gong Zhu, a player may expose ("sell") the cards Q♠, J, 10♣, or A (affecting all hearts) before each round, thus showing the card(s) to the other players. By the rules of "Gong Zhu", if a player exposes a card, he /she must not play it in the first trick when the dealer plays the corresponding suit, so as to be able to give a chance for players with higher cards to get rid of them without being disadvantaged by the exposure. The exception to this is when the exposed card is the only card in that suit (in any particular player's possession during that round). Exposing a card doubles its effect. For example, if the Q♠ is doubled, it will be worth -200 instead of -100. In the case of the 10♣, since it isn't worth  anything in itself, the doubling effect of the 10 of clubs is doubled, which if exposed and taken by that same player, will quadruple the value of all the other point cards collected in that round. Playing. In each trick, similar to Hearts, the suit is determined by the dealer who produces the first card. Players take turns to play a card in an counterclockwise direction and whoever produces the card of the largest value in the same suit collects all four cards and becomes the next dealer. Unlike Hearts, apart from exposed cards (as mentioned above), any card can  be played during the first trick. At the end of a round, all players' points are totaled up and added to their accumulated points for that game. Player(s) who have accumulated -1000 or lower points immediately lose that game. After which, a new game begins and all points are reset to 0. - Point addition (Non-exposed cards) Scoring. - Point addition (Exposed cards) - Point deduction (Non-exposed cards) - Point deduction (Exposed cards) - Not involved cards Like Hearts, points calculated are on an accumulative basis; usually, players will be given the points that are assigned to whatever point cards he collected after  one round. There are multiple ways to shoot the moon. Gong Zhu differs from hearts in that a player gains points by shooting the moon, instead of making other players lose points. In some cases, the J and the Q♠ switch values, giving negative points to unsuspecting players.
