Play Pinochle

Can you predict your score correctly by looking at the cards in your hand? In this 4-player game, you and the opposite player will be teammates such that 2 partnerships are formed. 2 decks of standard playing cards will be used with 2's to 8's removed, resulting in 48 cards. The ranks of the cards from highest to lowest are A-10-K-Q-J-9. Each player will first be dealt 12 cards, and then the bidding phase begins. The dealer is required to make a bid by predicting the total points he and his teammate can earn in the current hand. The bid must be a multiple of 10, and each bid must be greater than the previous one. When you are not the dealer and if you do not wish to make a bid, you can click the Pass button on the screen during your turn. Note that you must make your choice within the given time limit, as indicated by the timer on the screen, or you will lose. If all players choose to pass after the last bid, the player who made that bid will become the winner, and he can choose a suit as the trump of the current hand.
After the bidding phase, the melding phase begins. If the cards in a player's hand can form special patterns, i.e. melds, points will be awarded. The melds and their corresponding points are as follows: a Run (A, 10, K, Q and J of the trump suit) - 150 points; a Double Run (A, A, 10, 10, K, K, Q, Q, J and J of the trump suit) - 1500 points; a Marriage (K and Q of the same suit) - 20 points; a Trump Marriage (K and Q of the trump suit) - 40 points; a Dix (9 of the trump suit) - 10 points; an Aces Around (4 A's of different suits) - 100 points; a Kings Around (4 K's of different suits) - 80 points; a Queens Around (4 Q's of different suits) - 60 points; a Jacks Around (4 J's of different suits) - 40 points; a Double Around (8 A's, K's, Q's or J's) - 10 times the respective around points; a Pinochle (J of diamonds and Q of spades) - 40 points; a Double Pinochle (both J's of diamonds and both Q's of spades) - 300 points. One card cannot participate in two melds of the same type, for example a Q of spades and two K's of spades can only receive the score for one Marriage, but the Q of spades can also be used to form a Pinochle with a J of diamonds.
After the melding phase, the playing phase begins. The winner of the bid can play the first card, and the suit of that card will become the leading suit. The remaining players must follow suit if possible. If the leading suit is also the trump suit, the players must play a higher ranking card if they can. After all players have played a card, the player who played the highest ranking card of the leading suit, or the highest ranking card of the trump suit will win the trick. The winner of the trick will then start the next trick by playing a card from his hand. When all cards in the players' hands are played, points are calculated based on the tricks won. Each A, 10 and K won is worth 10 points, and the winner of the last trick will also receive 10 points. The score of a team will be the sum of the points from the melds and the tricks won by the teammates. For the winner of the bid, if his team's score in a hand is less than the bidded score, the bidded score will be deducted from the team's total score, otherwise the team's score in the hand will be added to the total score. For the team which did not win the bid, the score in the hand will always be added to the total score. When the total score of a team has reached 1000, the game is won.
