You have a partner, which is the player located across you at the table. Each player starts with 13 cards. The goal with each hand is to bid a number and then obtain exactly this number of tricks. The right to start bidding and put down the first card is passed from player to player. You have to follow suit if possible.
Spades is the trump colour.
In other words, if you bid 5 and your partner 3, you'll gain 80 points. Should you on the other hand capture more than eight tricks, you will receive 1 point and one bag for each trick in excess. The downside being that you lose 100 points when you have accumulated 10 bags. The game ends when a team breaks the finishing line at 500 points.
