Multiplayer All Fours

All Fours is a 4-player card game originated in England in the 17th century. It was then brought to North America and became the national game of Trinidad. A deck of standard playing cards will be used, and the two players sitting opposite to each other will become teammates such that 2 partnerships are formed. At the beginning of each hand, the dealer will first deal 6 cards to each player, and then reveal the topmost card from the remainder. The suit of the revealed card may become the trump used in this hand, but the player on the right of the dealer has the right to choose whether to accept that suit as the trump or not. If he does not accept it, the dealer can choose to keep that suit as the trump while giving 1 point to the opponents, or to select another trump. If the dealer agrees to select another trump, he needs to deal 3 more cards to each player, then reveal the topmost card from the remainder. If the suit of that card is still the same as the previously revealed card, he needs to deal 3 more cards to each player and reveal another card, and the procedure repeats until the revealed card is of a different suit. If all cards are dealt before revealing a different suit, the cards will be collected, reshuffled and redealt. When the dealer is revealing cards, his team will immediately get 1 point if an A is revealed, 2 points if a 6 is revealed, and 3 points if a J is revealed. After the trump suit is set, the player on the right of the dealer will play the first card, and the suit of that card will become the leading suit. The turn then goes in counterclockwise direction. If a player has a card of the leading suit, he can either play a card of the leading suit or a trump. If a player does not have a card of the leading suit, he can play any card. After all players have played a card, the highest ranking card of the leading suit when no trump is played or the highest ranking card of the trump will win the trick. The player who played the winning card can
