Multiplayer Hakka Cards 1.0.3

Hakka Cards is a trick-taking game for 4 players which dates back to the Ming Dynasty (1368 – 1644) in China. The cards contain 4 suits, namely Sup, Gon, Zok and Sin in descending ranking. Each suit has a total of nine cards with numerical values 1 to 9. An additional card is called "Wan Sin," which has a numerical value of 1 but does not belong to any suit.

Each hand of the game consists of 4 phases, namely Dealing, Calling, Playing and Scoring. Your goal in the game is to win 6 or more tricks so as to score points. To win tricks, you can form the following patterns with the cards in your hand:

Run - 3 or more cards of the same suit and consecutive numbers (first ranked by suit and then by number)
Set - 3 or more cards of the same number (ranked by number)
Single Card - a card of the highest ranking suit in your hand must be played (ranked by number)

Note that the 9s of all suits, the 1 of Sup, the 1 of Sin and the Wan Sin are also called the "Elder cards" at the start of the game. During the game, the Elder cards will change based on the cards that are unbeatable, for example if the 9 of Sup is played, the 8 of Sup will become an Elder card as it is unbeatable now. The Elder cards are marked with a star and are unbeatable when played as a Single Card. Note that if you are playing a Single Card, you must play a Non-Elder card of the highest ranking suit before playing an Elder card in your hand, unless you are the Privileged Player as mentioned below. More special cases are listed as follows:
