Spades is a Trick Collecting card game in which you attempt to collect a target number of tricks that you bid at the start of each Match.

A standard 52 Card Pack is used for Spades.

A / Ace [highest] - K - Q - J - 10 - 9 - 8 - 7 - 6 - 5 - 4 - 3 - 2 [lowest]

The Spade Suit is always the Trump suit.

The Dealer is chosen randomly at the start of the match, and then the turn to deal moves clockwise after every game.

After looking at their cards, each player predicts how many tricks they will be able to take. Moving in a clockwise direction, the player to the dealer's left starts the bidding process and, in turn, each player predicts how many tricks they expect to win for the round. There is only one round of bidding, and the minimum bid is NIL (or zero). Every player must make a bid on their turn and no player may pass. Players do not call a suit in their bids, as the Spade suite is always trump.

The game is scored per round based on each bid and the hands collected; the overall winner must make a certain number of points defined as the "target" for the match.

The player on the dealer's left plays the opening hand, and players must follow with the same suit, if possible. If a player cannot (because they do not own cards of that suit), they may play a trump card (always the Spade) or any other card (which cannot win the hand). The trick is won by the player who plays the highest trump card, or if no trump was played, the player who played the highest card in the suit that led the hand.

The player who wins the trick leads the next hand. Play continues until none of the players have any cards left. The Spade Suite cannot lead a hand unless played previously or the player to lead, has nothing but Spades in their hand.

For making the number of tricks bid, the player scores 10 points for each trick bid, plus 1 point for each trick one over the trick, AKA overtricks.

For example, if a player's bid is five (5) and they collect seven tricks, their score would be fifty two (52). Fifty (50) points for the bid, and two (2) points for the additional overtricks.

If a player bids four (4) and they collect four (4), their score would be forty (40).

In addition, overtricks result in the accumulation of "bags" and a deduction of points is made every time a player accumulates a certain number of bags in the match.

If a takes fewer than the number of tricks bid, the score is -10*(number of tricks bid). For example, if a player bids three (3) and wins only two (2) tricks, the player's score is minus thirty (-30) for that round.
If there is a tie, all players participate in one more round of play, and the player with the highest score at the end of that round is the winner.

Therefore, the object is to attempt to meet the target score before other players do, and have the most points in case of multiple players meeting the target score in the same round.
