Mirror Spades

Look at your hand, count your spades, and bid that number. Six spades is a bid of six. Two spades is a bid of two. There is nothing else to decide and no way to shade the number up or down.

Everything else stays standard. Fifty-two cards, four players in two partnerships, thirteen cards each, thirteen tricks. Spades are trump, you follow suit if you can, no spade may be led until spades are broken. Contracts pay ten a trick and cost ten a trick when missed, bags are worth a point each, and ten bags cost a hundred.

A few tables allow bidding one above or one below your spade count. That is a softer variant, and it destroys the property that makes mirrors interesting, so it is worth knowing that it is not the same game even though it is often called by the same name.

There are thirteen spades in a fifty-two card deck and all of them are dealt. Every spade sits in exactly one of the four hands. Since each player bids their spade count, adding the four bids together adds up every spade in the deck, and the total is thirteen every single hand without exception.

This is not a curiosity, it is the strategic core of the variant. The board is always exactly thirteen, which means every trick in the hand has been bid for by somebody. There is no slack, no unclaimed trick, and no free overtrick anywhere on the table.

The consequence follows directly: bags and sets are locked together one for one. If your team takes a trick beyond its bid, the opposing team is now one trick short of theirs. You cannot collect a bag without setting an opponent, and you cannot be set without handing an opponent a bag. In standard Spades those two things are independent. In mirrors they are the same event seen from two sides.

It also means you know the exact bid split the moment bidding ends. If you bid four and your partner bid three, the opponents hold exactly six spades between them and owe exactly six tricks. There is no ambiguity to work around.

A hand with zero spades is an automatic nil. You did not choose it, you cannot decline it, and you have to duck thirteen tricks holding a hand that may well contain three aces.

It is rare. A thirteen-card hand is void in a specified suit roughly one point three per cent of the time, which works out at about one hand in seventy-eight. Across a full game to five hundred you might see one, and quite possibly none.

Scoring a forced nil is a genuine house decision. Many rooms score it exactly like a normal nil at one hundred and minus one hundred. Some reduce it to fifty on the grounds that the player had no choice in taking it. A few let a spadeless player bid a number instead, which is the kindest rule and the one that breaks the total-thirteen property, since the bids no longer sum correctly.

If you are the partner of a forced nil, treat it as an ordinary nil defence problem with one extra piece of information: your partner is void in spades, so they can never ruff and will be discarding from trick one on any spade lead. Every spade lead is a free discard for them, which makes protecting them easier than it looks.

Because every bid is a spade count, the bidding tells you exactly how many trumps each player holds. No other Spades variant gives you this. A player who bid three has three spades, and once they have followed to three spade leads they are void in trumps and can never ruff again.

Drawing trump therefore becomes arithmetic rather than guesswork. If the opponents bid four and two, they hold six spades between them, and after three rounds of spades you can state precisely how many are left and who has them. Planning a side-suit run around that is completely reliable in a way it never is in standard Spades.

The cost is symmetrical: you cannot conceal your own trump length. Everyone at the table knows how many spades you hold and can count exactly when you run out. Bluffing about trumps does not exist in mirrors, which is why so much of the skill moves into timing.

Bid shapes are worth recognising. Thirteen spades across four hands most often produces splits like four-three-three-three or four-four-three-two, so bids of three and four are the everyday case. A bid of six or seven announces a genuine trump monster and the entire table will play the hand around it, usually by starving that player of side-suit leads.

Here is the tension that makes mirrors a real game: your bid is set by spade length, but your tricks come from total strength, and the two frequently disagree.

Consider three low spades, the ace of hearts, the ace of clubs and the ace of diamonds. Mirrors makes that a bid of three, and the hand will naturally take six. You must lose three tricks on purpose. That means ducking the first round of your ace suits, discarding winners on tricks your partner has already won, and refusing to ruff when ruffing is easy. Deliberately throwing tricks away is a skill that barely exists in standard Spades outside of late bag control, and in mirrors you will need it in roughly half your hands.

The opposite hand is just as awkward: five low spades and nothing else. That is a bid of five on a hand that wins two by itself. You have to manufacture tricks by ruffing early and often, which means getting yourself void in a side suit as fast as possible and hoping your partner leads it. Waiting politely for trumps to be broken is how this hand gets set.

Because your partner knows your exact spade count, the two of you can plan the whole hand from bidding. If you bid five and your partner bid one, the team owes six and your partner should be spending the hand feeding you ruffs rather than chasing tricks of their own. That kind of division of labour is much easier here than in standard Spades, where nobody knows anyone's real trump length.

In standard Spades an overtrick is worth one point and a step toward a hundred-point penalty. It is a liability you tolerate. In mirrors it is a weapon.

Work the numbers. The opposing team bid seven. You take one trick more than your contract needs. They are now set, which turns their plus seventy into minus seventy, a swing of one hundred and forty points, and your side of the transaction is one bag. Ten of those bags cost you a hundred. The trade is not close.

This is the strategic conclusion that separates mirrors from every other Spades variant: take the extra trick. Aggressive overtricking is correct here in a way it is never correct in the standard game, because the board is exactly thirteen and there is no such thing as a harmless overtrick for anyone.

The defensive half of the same idea is that your own contract has no cushion. Every trick you fail to win is a trick an opponent gains, and there is no unbid slack to absorb the difference. When you cannot land exactly on your number, aim high rather than low. Overshooting costs you a bag and sets an opponent. Undershooting sets you and rewards them.

Mirrors is the right call when the bidding is the problem. It levels tables with mixed experience instantly, because the player who has spent five years learning to bid accurately has no advantage at all in the phase where they were strongest. What remains is card play, which is a fairer test and a faster one.

It is also a genuinely good teaching format. Beginners who freeze at the bid can play a full hand without agonising over a number, and because contracts are frequently mismatched to hand strength, they get forced practice at both throwing tricks away and stealing them.

The obvious drawback is that if the bidding argument is your favourite part of Spades, mirrors deletes it. Most groups run it as a rotating special round rather than a whole game, alongside other special hands, which keeps the novelty and avoids the point where forced bids start to feel arbitrary.
