What's a Nil bid in Spades?

A bid of 0 — you predict your team will win zero tricks from your hand. Make it and your team scores +100. Take even one trick and the bid fails for -100. Your partner's bid still has to be made separately. Nil is the highest-variance play in Spades; pick it only when you have no Aces and only low spades.

Why are overtricks ('bags') penalized?

Each overtrick scores 1 point on its own, but every 10 your team accumulates costs you 100 points. The penalty exists to discourage low-balling — bidding 1 and winning 4 would be too cheap. The bag rule pushes teams to bid honestly and not over-deliver.

When can I lead a spade?

Only after spades have been broken — meaning a spade has already been played as trump on an earlier trick (because the leader played a non-spade and someone else was void in that suit). If spades are all you have left, you may lead them; that also counts as breaking.

What happens if my team's score drops to -200?

The game ends and your team loses. Spades has both a win line (500) and a loss line (-200). A string of failed bids, missed Nils, and bag penalties can push you there; aggressive Nils early when you're behind are the fastest way to dig the hole deeper.

How Do You Play Spades?

Goal: bid accurately, take your tricks, and reach 500 points before the other team.

Setup

Teams: you (South) partner with North; West and East are the opposing team.
Deal: 13 cards per player from a standard 52-card deck.
Trump: spades. Any spade beats any non-spade in a trick.

Rules

Each player bids 0–13 tricks. A bid of 0 is "Nil" — a promise to win no tricks at all, worth +100 if made and -100 if failed.
Your team's combined bid is the sum of both partners' bids.
Follow suit if you can; otherwise play any card, including a trump spade.
The highest card of the lead suit wins the trick, unless a spade was played — then the highest spade wins.
Spades cannot be led until they have been "broken" (someone played a spade as trump on an earlier trick).
Make your bid for 10 points per trick. Overtricks add 1 point each but count as "bags" — collect 10 and your team loses 100.

Strategy

Count your sure tricks before bidding. Each Ace is roughly one trick; the Ace, King, and Queen of Spades are near-guaranteed. Add maybe half a trick for a singleton (you can trump in early).
Bid Nil when your hand has no Aces and low spades. A Nil hand wants weak cards in every suit so opponents can over-take you.
Support your partner. If they've made their bid already, ease off — let opponents take tricks instead of stacking bags on your team.
Cover a partner's Nil. When your partner is on Nil, lead high to draw out cards that might hand them a trick. Take any trick yourself rather than risk it falling on them.
Force out trumps. Leading a long side suit makes opponents follow until they're void; once void, they'll trump in with spades. Use this to flush their spades before yours.

A Short History

Spades was developed in the United States in the late 1930s, almost certainly out of Whist and Bid Whist. It spread through U.S. college campuses and military bases during World War II and the 1950s, then onto Microsoft Windows in Microsoft Plus! 98 and Windows XP, where it became most players' introduction to the game.
