Spades

Spades is a partnership game: you sit opposite North; West and East are your opponents. Spades are always trump. First team to 500 points wins (a team that falls to −200 loses).

Bidding

After the deal each player bids how many tricks they expect to win (0–13). Your team's contract is the sum of both bids. Bidding Nil means you promise to win no tricks at all: +100 if you succeed, −100 if you fail (your partner's bid is scored separately).

Play

• The player left of the dealer leads. You must follow suit if you can; otherwise you may trump with a spade or discard.
• Spades can't be led until they are broken (a spade has been played on another suit), unless you hold only spades.
• The highest spade wins the trick, otherwise the highest card of the suit led.

Scoring

• Make your contract: 10 × bid, plus 1 point per extra trick (a bag).
• Miss it: −10 × bid.
• Every 10 bags accumulated costs your team 100 points.
