Gridiron Grids
Fill a 3x3 grid with NFL players who fit both the row and the column.
Every day: One numbered 3x3 NFL grid a day, the same for everyone: name a player for each square who fits both its row and column, scored on how rarely others picked him. New puzzle: 8 PM Eastern Time, as the site states.

Gridiron Grids is a daily NFL trivia grid from the team behind HoopGrids. Each square crosses two categories, such as a team and a stat like two or more sacks in a game, and you name a past or present player who fits both. Guesses are unlimited, so the challenge is finding rare answers rather than just correct ones.
About Gridiron Grids
Gridiron Grids brings the row-and-column trivia grid to the NFL. Three categories sit across the top and three down the side: teams, teammates or coaches, and career or season stats and accolades. Each of the nine squares needs one player who meets both of its labels. The site says it is run by HoopGrids, the NBA grid, and the two share accounts, rules and look.
The rules are spelled out on the site, and they matter. Categories are independent: for a Chicago Bears square crossed with two or more sacks in a game, the player needs at least one regular season or playoff game for the Bears and a two-sack game at some point in his career, not necessarily in Chicago. For two teams, the player needs a game for each, in any seasons. Unlike the Immaculate Grid, there is no limit on guesses, and you can change a square even after the grid is finished.
Scoring is about rarity. Each correct answer shows what share of players worldwide picked the same name, and the least picked answer in a square earns a unicorn. A Reverse Mode flips this and asks for the most common answer instead, and a hint mode shows six candidates. A new grid goes up every evening at 8 PM Eastern, older grids are in the archive, and an account puts you on the daily leaderboard and keeps your games across devices.
It suits NFL fans who know rosters across eras, and players of HoopGrids or the Immaculate Grid who want a football board with unlimited guesses.
How to play Gridiron Grids
- Open Gridiron Grids to load the day's numbered grid.
- Pick a square and read its row and column categories.
- Type a past or present NFL player who fits both, and choose him from the list.
- Keep guessing until every square is filled; there is no limit on guesses.
- Check the rarity of each answer, try Reverse Mode for the most common picks, or play older grids in the archive.
Tips
- Read the categories as independent: a stat need not have been achieved with the team in the same square.
- For team and team squares, journeymen and backups are often the rarest valid answers.
- Since guesses are unlimited, go for an obscure name first and fall back to a star if it misses.
- Coach and teammate squares only need one shared game, which opens up short stints.
- Sign in if you want your result on the daily leaderboard.
