How to Run a Squares Pool for the NBA Playoffs

Most squares pools are built around a single game. You set up a board, collect money, assign numbers, and pay out the winner(s). The math is clean because the event is fixed.

A best-of-seven playoff series breaks that assumption. When you start a series pool, you don't know if you're running four games or seven. That uncertainty ripples into every part of your pool: how much players commit upfront, how the prize pool gets funded, how payouts are structured, and how much ongoing work the host takes on.

The Super Bowl has none of these problems. One game, one board, done. A playoff series demands a deliberate setup decision before you collect a single dollar, which is exactly what this guide is for.

What it is
This is your traditional approach. Each game in the series gets its own squares board. You collect from players before each game, assign numbers for that board, and pay out after that game. Then repeat for each game.

Best for
Engaged groups where players want the flexibility to opt in or out per game. With games typically played every other day during a series, this option requires the most involvement: a fresh board, square selections, and a new collection round before every game. Make sure everyone is ready to move fast when each new squares board opens up.

Pros:

• Maximum flexibility — players can opt in or out per game, and you can refresh numbers, winning conditions, and prize pools each time

Cons:

• Most labor-intensive option — setup, square selection, and payment collection needed for every game

What it is
A single board spans the whole series. Everyone pays in once before Game 1, the total prize pool is set, and the same grid and numbers apply to every game. Each game pays a guaranteed minimum, the clinching game pays a premium, and if the series ends early the remaining prize money is redistributed to the games that were played. Decide all of this before anyone sends money to avoid confusion later on.

How payouts work
The guaranteed minimum per game is based on a worst-case 7-game series, the lowest each game would ever pay. The clinching game always pays a premium on top of that floor. If the series ends before Game 7, unplayed games never pay out and their allocation rolls into a bonus on top of the minimum for the games that were played. A sweep is the best outcome for anyone who won a square. Fewer games means more money per game.

Best for
Organized groups, office pools, and fundraisers that want one-and-done admin. Collect once before Game 1, set the rules, and your main job for the rest of the series is watching basketball.

Pros:

• Least ongoing work for the host and players
• Short series reward early winners with a bonus — built-in excitement if a sweep is on the table
• As a player, it's easier to remember 1 set of numbers for the whole series instead of 7 different sets

Cons:

• Per-game payouts shift as the series progresses, which can confuse players if the rules aren't communicated clearly upfront

If your group wants full flexibility, Game-by-Game is the right call. Nobody overcommits, late joiners can still play, and each game stands on its own. Just know going in that you're signing up to run a mini-pool every other night for up to seven games.

If you want to set it and forget it, Fixed Prize Pool is the better fit. One collection, one board, one set of rules. The only real homework is deciding your payout structure upfront, specifically what happens if the series ends in four or five games, so there's nothing to argue about when it does.

A four-game sweep is the scenario every host should think through in advance, because it's not rare. Since 2000, roughly 20% of NBA playoff series have ended in four games.

On a game-by-game board, an early series end is a non-issue. Each completed game paid out on its own board. If Game 5 never happens, there's no Game 5 board and no expectation of one. Clean and simple.

On a fixed prize pool board, a short series is actually good news for winners. With a guaranteed minimum structure, unplayed games never pay out and their allocation rolls into a bonus on top of the minimum for the games that were played. The rules are set before Game 1, so there's nothing to dispute when the clinching game comes earlier than expected.

Here's how a $1,000 prize pool plays out across two scenarios: a 4-game sweep and a full 7-game series. The pool is split into an $800 guaranteed base and a $200 bonus, with the clinching game paying double a regular game. Payouts are based on the final score only.

Every winner is guaranteed at least $125 regardless of how the series goes. Win a square in a sweep and that amount becomes $200, with the clinching game paying $400. The shorter the series, the better for everyone who won a square.

Any edge case that involves money needs a written answer before the series starts. Work out your payout rules, short-series scenarios, and clinching game premium before you collect a dollar — or use a platform that handles all of it for you so there's nothing to argue about when the unexpected happens.

Squares pools pay out based on the last digit of each team's score at set intervals during the game. In the NBA, those intervals are the end of each quarter and the final score — giving you four payout opportunities per game.

At the end of the first quarter, you look at the last digit of each team's score and find the square where those two numbers intersect on the grid. That square wins. The same process repeats at halftime (end of Q2), end of Q3, and the final buzzer.

For example: if the score at the end of Q1 is 28–31, the winning square is where 8 (last digit of 28) and 1 (last digit of 31) intersect on your grid.

A single payout on the final score is the simplest option, but many hosts add quarter payouts, reverse scores, neighboring squares, or other variants to keep engagement high throughout the game. As a host, you choose what fits your group.

Getting paid upfront is always easier than chasing money after a game has already been played. Fixed prize pool hosts have it simplest. Collect once before Game 1 and you're done. Game-by-game hosts need a reliable way to remind players and track who's paid before each game. Send reminders early and often, not the day of. If you wait until tip-off, you're signing up for a bad time.

Whichever approach you use, be explicit upfront about when money is due and what happens if someone doesn't pay. A simple message when you launch the pool is all it takes.
