Somebody in your circle has hosted this evening without ever calling it by name. Sixteen people, four card tables borrowed from the neighbours, a tally card at every seat, and a rule that after four deals the winners get up and move. That is progressive bridge, sometimes called party bridge, and it has probably introduced more people to the game than any club ever has.
It deserves a proper explanation, because most hosts learn it by imitation and end up inventing half the rules on the night.
The movement is the whole idea
Progressive bridge is built on one principle: nobody stays put and nobody keeps the same partner. You set out your tables and number them, table one being the top table. Four players sit at each. Everyone plays a fixed number of deals, usually four, then the totals get compared.
The pair with the higher score at each table moves up one table. The losers stay where they are. At the new table partners switch, so the person sitting across from you is someone you have not played with yet. Run six or seven rounds of that and everybody has partnered half the room.
Table one has nowhere to go up, so its winners stay and its losers drop. Hosts handle that corner differently. Agree on it before the first card is dealt, not during round three.
Scoring is individual, and that changes everything
Every player carries their own tally card and keeps a personal running total. Not the partnership's total. Yours. Since your partner changes every round, the only thing that persists across the whole evening is you, and the winner is simply the highest individual score in the room.
The scoring itself is rubber scoring with the rubber taken out. Trick values are normal. Bid and make a game contract and you collect the game bonus on the spot, commonly 300, or 500 if the host is bothering with vulnerability at all. Make a partscore and you take a small fixed bonus, usually 50, and then the slate is wiped for the next deal. Slam bonuses apply as normal. Nothing carries forward, ever.
Plenty of hosts skip vulnerability entirely, and that is a perfectly defensible call for a party. If cutting the rubber loose sounds familiar, it should: Chicago solves the same problem in a tidier way, and the comparison of rubber against duplicate covers why the rubber gets dropped at all.
What the format is genuinely good at
Mixing people. That is the honest answer, and it is not a small thing.
A rubber evening locks four people together for hours, which is lovely when the four are well matched and fairly grim when one pair is drowning. Progressive breaks that up every twenty minutes. The strongest player in the room ends up partnering the newest one at some point, and usually both enjoy it more than they expected. Nobody is trapped.
It also scales, which almost nothing else at home does. Rubber bridge with twelve people is three separate games in the same house. Progressive bridge with twelve people is one game, and somebody wins at the end.
The thing it cannot tell you
This is where my enthusiasm runs out.
Every table shuffles and deals its own cards. Round three at table two bears no relationship whatsoever to round three at table four. So when Margaret finishes the night 2,400 points clear of the field, nobody in the room can say whether she played beautifully or simply picked up more aces than everyone else.
Probably some of both. The problem is that you cannot separate them.
Card distribution across twenty-eight random deals is not fair, not remotely, and progressive bridge has no mechanism to correct for it. The player who held four flat twelve-counts in a row is not being measured against the player who was dealt two slams. They are just being added up. Most people are fine with that, and I would not lecture a room having a good time. But when the same person wins three nights running, somebody eventually wonders how much of it was the cards.
Taking out the luck without taking out the party
The fix that duplicate clubs settled on a century ago is to stop shuffling. Deal the hands once, have everyone play the same cards, and compare like against like. Your 620 stops being 620 and turns into "better than four of the six pairs who held this," which is a claim about your play rather than your luck. That is most of the argument for playing pre-dealt hands in the first place.
Doing that at home used to mean owning physical boards, duplicating the deals and running a movement, which is a lot of machinery for a Tuesday. Tools like Bridge@Home take care of the awkward part: your table of four plays a set of pre-dealt hands, the scoring is handled properly, and afterwards you can see how your results stack up against other players who held exactly those cards. Same four people round your table. Very different question at the end of the night.
If you are the one hosting
Write the scoring rules on a card and put one on every table. Half the arguments at progressive evenings come from two tables quietly using different partscore bonuses, which nobody spots until the totals go up on the wall.
Four deals per round, not six. Rounds run longer than you think, and one table locked in a hand-wringing slam auction holds up the entire house.
Get a bell.
And settle in advance what winning is supposed to mean here, because the highest total and the best evening are not always the same thing, and a host who knows which night they are running tends to get asked to host the next one.
