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

What it is
This is the March Madness squares approach applied to the NBA. One board covers every game from the first round through the Finals, the numbers get randomized once before the first round tips off, and every game pays against that same grid. Leave the Play-In Tournament off the board: the field isn't set until it ends, and starting with Game 1 of the first round keeps the board to best-of-seven series only.

Label the axes home and away, not by team
The teams change from game to game, so the grid can't carry team names the way a single-series board can. Put the home team along the top and the away team down the side, and every game reads the same way no matter who's playing. On a single-series board, use the two team names instead: home court switches during a series (the 2-2-1-1-1 format), and players find it easier to follow "my 7 is the Knicks" than to keep track of who's hosting tonight.

How payouts work
The total number of games isn't knowable in advance. Fifteen best-of-seven series can produce as few as 60 games or as many as 105, so price each round against the most games it could produce, the same guaranteed-minimum logic as the fixed prize pool above, and send whatever the shorter series leave unspent to the last prize of the Finals. Early rounds usually pay on the final score only; as the games thin out, plenty of hosts add a halftime prize or the reverse score rule for the conference finals and the Finals. Here's a $1,000 prize pool built that way:

Every game pays at least its listed amount. If the first round wraps up in 44 games instead of 56, the twelve games that were never played leave $60 unspent, and that $60 joins the last prize of the Finals. That means the last prize isn't a fixed figure until the Finals end, so tell players that upfront: the game that ends the Finals pays its $20 plus a last prize that starts at $230 and only grows.

Best for
Office pools and bigger groups that want one thing to follow for two months. Collect once, randomize once, and every playoff night has something riding on it, including the series between teams nobody in the group follows.

Pros:

• One collection and one set of numbers for 60 or more games
• A rooting interest in every playoff game, not just your team's series

Cons:

• The most involved payout math of the three, which has to be written down before the first round starts
• Players who draw cold numbers early have a long wait for the bigger prizes later in the playoffs

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.

If your group wants the whole postseason in one place, One Board for the Whole Playoffs gives you the most games for one collection. It takes the most planning upfront, but once the round-by-round amounts are written down there's nothing left to run except the games themselves. Whichever you pick, Play Squares boards can cover more than one game with the same numbers carried across all of them and a prize amount set per game, so a series or full-playoff board stays one board instead of a stack of separate ones.

A four-game sweep is the scenario every host should think through in advance, because it's not rare. Since the first round went to best-of-seven in 2003, 64 of the 360 NBA playoff series through 2026 ended in four games, nearly one in five, and every one of those postseasons had at least one sweep. First-round series are the likeliest to end early.

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, and share them in the same message that tells players what they owe, 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.

Basketball is also friendlier to every square than football is. NBA teams score dozens of times a quarter in steps of one, two and three points, so no last digit gets the head start that a 0, 7 or 3 gets from touchdowns and field goals. Drawing a 2 or a 5 on an NBA board isn't the death sentence it can feel like on a football board, which makes the random draw easier to sell to a group of first-time players.

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.

Whichever way you set the payouts, the scores themselves are tracked for you on an NBA squares board, quarter by quarter, so nobody has to work out the digits by hand while the game is still going. Running the pool online also means the board shows the pending winner while a quarter is still being played, so players can check it themselves instead of texting the host to ask whose square is on track. The same quarter mechanic is worked through with football examples in our squares rules guide, including how to handle overtime and a square that wins twice.

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.
