Football Squares Rules: How to Read the Grid and Score

Football squares uses a 10×10 grid: participants first buy or claim squares, then the numbers 0–9 are randomly assigned to each axis through separate, independent draws. At agreed checkpoints, the last digits of the teams’ cumulative scores identify the winning square.

This is American football, not soccer. “Super Bowl squares” is the same game played for the Super Bowl. You do not need specialist football knowledge to read the grid, but buying a square does not guarantee a payout.

In the standard version, the numbers remain fixed throughout the game. Ownership is settled before the draw, and the draw must be independent of the game.

How to read the grid and find the winning square

Find Team A’s last score digit across the top columns and Team B’s last score digit down the left rows. Their intersection is the winning square: a score of Team A 17–Team B 13 means column 7, row 3.

This is a local demonstration, not the production site. Random digit arrangements differ between the English and Russian versions. The heuristic cell colors do not measure likelihood or guarantee a win.

Team order matters: A 7–B 3 is not equivalent to A 3–B 7. Check which team belongs to the columns and which belongs to the rows.

Use the cumulative score since the start of the game, not points scored only during that quarter. If the score at the end of the third quarter is 17–13, the pair is 7–3 regardless of how many points were scored in that quarter alone.

On boards with square numbers from 1 to 100, those numbers identify locations, not the score digits 0–9 assigned to the axes. The generator shown here labels cells with score-digit pairs, such as 7–3, rather than square numbers.

How to set up a football squares game

Agree on the rules and fix square ownership first, then draw the numbers separately for each axis and share the completed grid. Once squares have been sold, do not change the format without explicit participant agreement and a refund arrangement for anyone who declines.

Follow this sequence:

1. Choose the event and grid. Record the teams, their axes, the grid size, the price per square, and the payment deadline.
2. Define the money. State the payout distribution and any organizer fee or donation. Record collected entry fees separately from the distributable pool.
3. Choose the checkpoints. For example, use the end of Q1, halftime, the end of Q3, and one final payout. Specify whether that last payout uses the end of regulation or the final score including overtime.
4. Resolve exceptions in advance. Cover unsold squares, an unsold winner at the final checkpoint, repeat winners, cancellations, disputes, and refunds.
5. Lock ownership. Close the purchase and payment records before drawing numbers.
6. Draw each axis independently. Shuffle ten slips numbered 0–9 and draw without replacement for the columns. Repeat with a complete set of 0–9 for the rows.
7. Record and share the grid before kickoff. Photograph or save it and distribute the record. Do not redraw later to obtain a preferred result.

A public draw or an auditable tool can make the procedure easier to inspect. A software label saying “random,” however, is not proof that the software cannot be manipulated. One published example is the Vergennes municipal organizer’s rules: after all squares are claimed, digits 0–9 are drawn from a hat, and the winning square is the intersection of the teams’ last score digits. These are one organizer’s pool rules, not a universal standard.

How payouts work: a fictional game

In this fictional game, square 7–3 wins twice, while the last payout depends on the overtime rule chosen beforehand. This is an illustration, not a historical game.

Q1, Q2, and Q3 mean the first, second, and third quarters. If the rules include overtime, square 7–4 receives the last prize at 27–24. If the rules use regulation, square 4–4 receives it at 24–24. There is one last prize, not both, unless an additional payout was separately agreed and funded.

The first three results stand either way. With four equal prizes of 250 USD, the owner of square 7–3 receives 500 USD in total for Q1 and Q3.

A tie maps normally: 24–24 produces 4–4. Four winning checkpoints do not require four different winners. Also, not every scoring change changes the last digits, and a score change outside a checkpoint does not itself trigger a payout.

How to divide the prize pool

With 100 paid squares at 10 USD each and no deduction, 1,000 USD is collected and available for prizes. You can divide it equally, increase prizes across the game, or pay only at halftime and the final checkpoint.

The shares total 100% in each distribution. “Final” here means the last checkpoint agreed in advance: regulation or the final result including overtime.

The table repeats every amount in the chart. These distributions change payout timing and size, not the guaranteed number of distinct winners. Two payouts need not go to two people, just as four payouts need not go to four.

Collected entry fees and the distributable pool are not always the same. If there is a commission or fundraiser deduction, subtract the agreed amount before allocating prizes. The 10 USD price is an example assumption, not a claim about a typical entry price.

How to use the football squares calculator

Enter the price per square and the number of squares purchased, then choose a payout distribution. The calculator assumes 100 sold squares and no deductions; its chance of winning at least once is a simplified model, not a verified probability for a real NFL game.

NFL stands for National Football League. Scores across its quarters, including repeated digit pairs, cannot automatically be treated as independent.

1. Set Price Per Square to 10.
2. Set Squares Purchased to 5.
3. Select Equal.

These inputs produce a 1,000 USD prize pool and four prizes of 250 USD. Your entry cost is 5 × 10 = 50 USD.

Halftime-Final produces only two positive payouts, each 500 USD. For an actual game, separately state whether the final payout uses regulation or the result including overtime.

The displayed input ranges are 1–100 USD for price and 1–10 for squares purchased. These describe the interface, not a promise that every possible input is enforced.

The tool does not account for unsold squares or deductions. It does not record owners or grid digits, accept payments, or track live scores.

For five squares, the displayed 18.55% comes only from a model of four independent checkpoints with equal chances. It ignores known digit pairs, score dependence, and ownership layout on a fixed grid. The interface’s generic verdict for five or more squares is not evidence of an optimal purchase or a recommendation to spend more.

Which football squares numbers are best?

Before a fair, uniform draw, there is no universally best physical square: each has a 1% chance of winning at a single checkpoint. After the draw, known digit pairs can have unequal probabilities.

American football scoring explains why digits are not equally common. Under NFL Rule 11, a touchdown scores 6 points, a field goal 3, and a safety 2. A try after a touchdown can score 1 or 2 points. Thus, 7 points can represent a touchdown plus a successful one-point try—not a touchdown alone.

Original English NFL 2026 document: Rule 11, PDF page 49, printed page 42.

Scores of 0, 3, 7, 10, 14, and 17 produce last digits of 0, 3, 7, 0, 4, and 7. A last digit of 2 can come from 12 or 22 points; it does not require a safety. A last digit of 5 is possible at 35 points, so it is not impossible.

Frequencies vary by period. The author’s data has not been independently reconstructed here; it is not a current or matchup-specific forecast.

Distinguish “Which digits will my square receive?” from “Which known pair will the score produce?” A uniform draw gives every physical square the same pre-draw chance even when score outcomes are uneven. It does not make every known score pair equally likely.

How probability and expected value differ

Before a fair draw, k distinct fixed squares have a k% chance of winning at one checkpoint. But the chance of winning at least once across several checkpoints needs a joint model; it cannot generally be calculated by assuming independence.

Why a square has a 1% chance before the draw

For any score outcome, a selected column has a 1/10 chance of receiving the required digit, and a selected row has a 1/10 chance of receiving its required digit. Independent, uniform axis draws give 1/10 × 1/10 = 1/100.

This assumes the draw is independent of the game. Regardless of how frequently particular score digits occur, every physical square can receive any ordered pair before the draw.

Only one square wins at a checkpoint. For k distinct squares, these mutually exclusive winning events add to k/100, even if the squares share a row or sit next to each other. Once digits are revealed, this argument no longer establishes a 1% chance for a known pair.

Why four checkpoints are not automatically independent

On a standard grid, axes and ownership stay fixed while the cumulative score develops within one game. Digit pairs can repeat, so 1 − (1 − k/100)^4 is not a general calculation of the actual chance of receiving at least one payout.

That calculation requires a joint model of checkpoint scores and the layout of your squares. The following table shows only an illustrative model with independent checkpoints and an equal chance at each one.

The illustrative formula for m independent checkpoints is 1 − (1 − k/100)^m. With five squares and four checkpoints, its exact result is 18.549375%, rounded to 18.55%. These figures do not guarantee a payout and are not verified probabilities for a particular fixed grid and game.

How to calculate expected value without independent quarters

Before a fair draw, your gross expected payout equals your share of the fully distributed prize pool. Expected value (EV), expressed here as the average expected net result, subtracts your entry cost from that gross expected payout.

For the standard grid:

• Gross expected payout: k/100 × distributable pool.
• Net EV: k/100 × distributable pool − k × price per square.

These examples assume all 100 squares are assigned, all prizes are paid, and there is no sponsorship. Quarter independence is unnecessary: linear expectation lets you add expected payouts even when results are dependent.

Zero EV means an average net result, not zero risk. You can spend 50 USD and receive no payout. With a 10% deduction, the expected loss is 5 USD.

After the draw, conditional EV depends on the probabilities of your known pairs at each checkpoint and the corresponding prize amounts. Weighted payouts can therefore change a specific square’s conditional EV, although pre-draw expected payout remains proportional to square ownership.

Buying more squares increases exposure and cost; it does not create an EV advantage per dollar spent. Choose an affordable fixed budget in advance.

How football squares variants differ

The standard version keeps one grid fixed for the whole game. Reverse squares, re-randomizing numbers, and 5×5 grids are separate variants that must be agreed before purchases.

Reverse digits do not mean redrawing the axes, and they do not justify a claim of exactly doubled winning probability.

Our 5×5 generator uses groups 0–1, 2–3, 4–5, 6–7, and 8–9. At 25 squares priced at 10 USD, the collected pool is 250 USD—not 1,000 USD. Covering four pairs per square does not itself create an EV edge.

How to prepare a grid with the generator

Open the Super Bowl grid generator, choose 10×10, set the price to 10 USD, enter Team A and Team B, and choose a payout distribution. Register participants separately because the tool does not maintain ownership records.

The tool initializes numbers when it creates the grid. A grid generated before participant registration should therefore not serve as the final draw for the standard game. Perform the final randomization only after ownership is fixed.

Use the page’s actual capabilities:

• Set the grid size, price, team names, and payout distribution.
• After registering owners separately, conduct the final number draw.
• Copying text produces blank name fields; it does not automatically transfer a participant list.
• Browser Print prints the page.

Do not assume downloadable PDF, Excel, or Google Sheets files, payment storage, or automatic scoring. The first image in this guide is an actual localhost demonstration of this generator.

What to record before play and at settlement

Save a short rule sheet before the draw, then compare each checkpoint’s cumulative score with the locked axes. This identifies the recipient and prize without changing the agreement during play.

Host rule sheet:

• Event, teams, and their axis assignments.
• Grid size, price per square, and payment deadline.
• Owners and paid squares locked before the draw.
• Two independent axis draws and a saved final grid.
• Collected fees, deductions or donations, and the exact distributable pool.
• Checkpoints, prize amounts, and overtime treatment.
• Repeat-winner rules and any additional prizes.
• Unsold-square rules, including the final payout.
• Cancellation, dispute, and refund procedures.

Choose a transparent unsold-square policy before drawing: the organizer buys those squares at the same price; prizes roll over under an agreed procedure with a final-payout rule; or the game is canceled with refunds. Do not automatically award free organizer squares or add fees.

If only 80 squares are paid at 10 USD, 800 USD has been collected. Do not treat the pool as 1,000 USD unless the shortfall is actually funded. The calculator’s 100-sold-square assumption does not represent those actual funds. As one example of terms set in advance, St. Joseph in Keene’s 2025 Super Bowl Squares rules used the final score including overtime, rolled an intermediate prize for an unsold square into the next prize, and awarded a final prize for an unsold square through a separate random draw; cancellation also triggered a random draw. These were the terms for one 2025 event, not universal rules.

At settlement, record the cumulative score, take the last digits in the correct team order, identify the square’s owner, and apply the agreed prize. For an unpaid square or canceled event, follow the written rule rather than creating a new one after seeing the outcome.
