Spades is a trick-taking card game devised in the United States in the 1930s and became popular in the 1940s. It is a partnership card game thatlike Bridgeis descended from the old English game of Whist. In generalthe goal of each Hand of Spades is to predict or Bid on how many Tricks you will take during that hand.
Basic Rules
Spades is a trick-based card game for 4 players. Players sitting across from each other are partners on the same team. The object of this game is to be the first team to reach 300 or 500 points.
The layout
Each player is dealt a hand of 13 cards from a 52 card deck. The hand is sorted by suitthen rank: ClubsDiamondsSpadesHearts. Cards that are out of play are darkened. 
Bidding
Starting with the dealereach player in turn bids the number of tricks she expects to win. Possible bids are from Nil to thirteen. The sum of partnership bids are called the contract. If a player bids Nil(meaning they expect to win no tricks)then they maydepending on the rule settingsbe allowed to exchange up to four cards with their partner once everyone else has bid.
How to play Spades
The game begins with all cards being dealt. Each player plays one card and together they are called a trick. To start you must estimate how many tricks you think you can take with your hand. Your bid and your partners are then added together and this is the number of tricks your team must take. Play begins with the player to the dealer's left leading a card. The highest card in that suit wins the trick. Now for the tricky part and the reason the game is calls Spades. If you are out of the lead suityou can play any card you like. If you play a Spade and no one else doesyou win the trick. So Spades are trump cards. In this case the highest Spade wins. 
The game does not allow ties for first place. In the case of a tie for firstthe game will continue until there is a clear winner. This is true of both games ending at a point value and timed games.
Scoring
Tricks count ten points each for a partnership if the contract is madeand ten against if it is set. Bagsor tricks won in excess of the contractcount as one point each. This isn't a bad thing per sebut if you gather 10 bags you will deducted 100 points. Not all Spades games use bagsbut ours does. You can opt to bid nothing which (Nil bid)if successfulwill reap your team extra 100 points. -100 if you fail. For Blind Nilthese values are doubles (200 points).
