How to run a pool tournament at a bar

Pick a format that survives the number of people who turn up

This is the decision everything else hangs off, and most people get it wrong by reaching for a bracket.

A single-elimination bracket with twenty-four entrants needs five rounds, and it knocks twelve people out in the first twenty minutes. Those twelve finish their drink and leave. From the bar's point of view you have just run a promotion that emptied the room at nine o'clock.

A rotation format does the opposite. In three strikes — Killer, if you learned it in a pub — everybody shoots one shot in turn, a miss costs a life, and three misses puts you out. With twenty-four people, nobody is eliminated until they have missed three separate times, which takes most of an hour. Everyone stays. Everyone has a turn coming round every few minutes. Everyone keeps buying drinks.

The practical rule: under eight players, a bracket is fine. Eight or more, run a rotation.

Set the buy-in, and collect all of it before you start

Five or ten dollars covers almost every bar night in the country. The buy-in is doing two jobs that have nothing to do with the prize: it makes people turn up on time, and it stops anybody wandering off at rack three.

Collect every entry before the first break. Not most of it — all of it. Chasing two people for five dollars each while twenty others stand around is the single most common way one of these nights goes wrong, and it is never about the ten dollars. It is that everyone else now knows the rule is optional.

Say the pot out loud once it is complete. "Twenty-two players, five each, that's a hundred and ten, paying three places." Nobody argues with a number that was announced at the start. People absolutely argue with one worked out afterwards by one person with a phone calculator.

Pay more than one place

Winner-takes-all is fine with six people and poisonous with twenty-four, because twenty-three people go home with nothing and a good proportion of them do not come back.

The standard scale:

Players	Places paid	Split
Under 6	1	100%
6–11	2	70 / 30
12–19	3	50 / 30 / 20
20+	4	40 / 30 / 20 / 10

Round each place down to a whole dollar and give the remainder to first. A bar pays out in notes, and counting out change in front of a room is a bad look for everybody. Our pot split calculator does this, including a house cut, if you would rather not.

Draw the order in front of everyone

Position in the rotation is a real advantage — shooting first means breaking into a tight rack, which is measurably harder than shooting fourth into an open one. So draw it, visibly, and draw it properly.

A hat works. So does an app. What does not work is going round the table in whatever order people happen to be standing, or letting anyone pick, because the question "why am I first again?" comes up at every night where the order was decided quietly.

One technical note if you are writing your own: do not shuffle by sorting a list against a random comparator. It is not uniform and it quietly favours certain positions. Use a proper shuffle.

Agree the three rules that cause every argument

Settle these out loud before the first break, every single week, even with regulars. It takes thirty seconds and it saves the night.

1. Does a scratch cost an extra life? Most common answer is yes. Either works. Finding out at 10pm, with a pot on the table and somebody on their last life, does not.
2. Does slop count? In three strikes it should. A lucky roll that saves somebody on two strikes is one of the better moments of the night, and calling every shot in a noisy room needs a referee you do not have.
3. Is the break free? Almost always yes — you break, then you take your shot, and a dry break costs nothing. The breaker is opening the rack for the person after them.

Keep the night moving

Here is the arithmetic that nobody does. Twenty players, three lives each, is roughly four hundred shots over a night. Every extra ten seconds per shot adds more than an hour.

So the things that look like fussiness are actually the whole game:

• Call the on-deck player, not just the shooter. The person who needs to know is the one who is not at the table yet. This alone saves ten to fifteen seconds a shot.
• Put the order somewhere people can see it. A screen, a whiteboard, anything. Every "whose turn is it?" costs the room twenty seconds.
• Keep a shot clock in your back pocket. Do not announce one unless you need it, and if you do, announce it as a general rule rather than aimed at the one person who is taking two minutes a visit.
• Rack while the previous player is still shooting. Obvious, and nobody does it.

Decide what happens when somebody has to leave

It will happen, usually around rack five, usually the person with a lift home. Have an answer ready: they are out, they take whatever placing they had earned, and they do not get their buy-in back. Say it kindly and say it once.

The alternative — refunding, or playing on their behalf — opens a negotiation in front of a room of people who have all paid the same money, and there is no version of that conversation that ends well.

A realistic run sheet

Time	What happens
7:30	Sign-ups open. Names go down, money comes in.
8:00	Entries close. Pot announced. Rules stated. Order drawn in front of everybody.
8:05	First break.
9:15	Field roughly halved. This is when the room is fullest.
9:45	Down to the last four or five. Put a shot clock on if it is dragging.
10:00	Winner. Pay out in front of people. Announce next week before anyone leaves.

That last line is the one that turns one night into a weekly. Announce the next one while the room is still full and still happy.
