What is a football squares board?
A 10-by-10 grid with 100 squares. One team is assigned to the rows and the other to the columns, everyone claims squares with their name, and after the numbers are drawn each square matches one row digit and one column digit. It is best known as a Super Bowl party game, but the same board works for any matchup.
How are winners picked?
At the end of each quarter (and at the final score), take the last digit of each team's score. The square where the rows team's digit meets the columns team's digit wins that period. Every digit 0-9 appears exactly once on each axis, so each period always has exactly one winning square.
How does the number draw stay fair?
Both axes are drawn with crypto.getRandomValues, the browser's cryptographically secure random generator — the same kind used for security keys. Each axis gets an independent, uniformly random arrangement of 0-9. Nobody, including the organizer, can influence or predict the draw.
What does "Lock board" do?
It freezes the board: names can no longer be added, renamed, or cleared, and the grid size cannot change. Lock before revealing the numbers so that nobody can change their pick after seeing where the digits landed. You can unlock at any time — the tool is yours.
Which size should I use — 100, 50 or 25 squares?
100 squares (10×10) is the classic and fits roughly 10-100 players. 50 squares (10 rows × 5 columns) suits medium groups and keeps single digits on the row axis. 25 squares (5×5) is best for small groups; each square covers a pair of digits (0-1, 2-3, and so on) on both axes.
How do the paired numbers work on 25 and 50 square boards?
Digits are grouped into five pairs: 0-1, 2-3, 4-5, 6-7 and 8-9. A square wins when the last digit of a score falls anywhere in its pair. If a team has 24, the last digit 4 falls in the 4-5 pair. The tool applies this rule automatically when it highlights winning squares.
Does this site handle money or entry amounts?
No. The site generates the board, draws the numbers, and highlights winners — nothing else. There is no feature for collecting entry amounts, gathering a shared prize, or dividing prizes between players, and none will be added. Prizes are whatever your group arranges on its own.
Can I play without any prizes at all?
Absolutely. Plenty of groups play purely for bragging rights — an office channel, a family chat, or the honor of picking next week's snacks. The board works exactly the same either way.
How do I print the board?
Press "Print / Save PDF". The board prints on exactly one Letter page in landscape, with team names and axis numbers included. "Print blank template" clears the names first if you want an empty board.
Where is my board stored?
Entirely on your device. Names, team names, numbers and scores are saved in your browser's local storage — there is no account and no server-side copy. The "Copy share link" button encodes the board into the URL itself, so sharing works without uploading anything.
Is it free?
Yes, every feature on this site is free. There are no accounts, no limits, and no paid tier.
Can I use the same board for basketball or other sports?
Yes. Any game with two teams and a numeric score works. For basketball, the usual convention is to settle winners at halftime and at the final score — see the basketball squares guide.
