Spades is a trick-taking card game in which you must partner with the player directly across from you to attempt to win the number of tricks you predicted you would win in your bid. When you bid, you look at the hand your holding and make a guess as to the number of tricks you will win. When you are the first player to play a card, other players must follow suit, as long as they have a card of that same suit. If not, the player can throw a card of any suit, including a spade which is always trump. The player with the highest card wins the trick.
