Lovers of Bridge will definitely enjoy the intriguing game of Spades. This game is played by 4 players, in which two players sitting opposite to each other are teammates such that 2 partnerships are formed. Your goal is to estimate the number of tricks you can win with the cards dealt to you. Spades are always trumps, followed by the leading suit according to the first played card in each trick. The rankings of the cards are A to 2 from highest to lowest.

At the start of each round, each player will be dealt 13 cards. You can click the "Show cards" button on the screen to view your cards, then click to bid the number of tricks you can win. You can also choose to bid "blind nil" by clicking the corresponding button on the screen. In this case, you will not be allowed to view your cards, and the bidding number of tricks you can win will be set as 0. After all players have made their bids, they will take turns to play a card from their hands. The suit of the first played card in the current trick will become the leading suit, and the other players must follow suit if they can, for example, if the first played card belongs to the suit of hearts, the other players must play a card from the suit of hearts if they can. If a player does not have cards of the leading suit, he can choose to play any card. Note that a spade cannot be used to start a trick unless another spade has been played in previous tricks. Note that you must finish your turn within the given time limit, as indicated by the timer on the screen, or you will lose. After all players have played a card, the player who played the highest ranking card will win the trick, and he will be allowed to start the next trick. The game continues until all cards in the players' hands are played.

Points will be calculated at the end of each round. If the combined number of tricks won by a team is equal to their combined bids, the team can receive points equal to the combined bid times 10. If the number of tricks wo
