Immaculate Grid is a game that blends strategy, knowledge, and entertainment as players aim to complete a 3-by-3 grid with correct player names that align with specific categories. The game's ingenuity lies in its clever design, with three categories displayed at the top and three others on the side. Players are required to match players' names with the precise criteria provided by these categories. The difficulty level increases as the criteria cover a variety of aspects, including teams, accomplishments, movies, championships, coaches, and more.

Here are the rules for playing Immaculate Grid Football:
- Choose a player for each cell that satisfies the criteria for that cell's row and column.
- You have nine attempts to fill out the grid, and each attempt, whether correct or incorrect, counts as a guess.
- A new grid is available every day at 9:00 am ET.
- Each player can only be used once.
- Players can be active or inactive (NFL, AFL, or AAFC), and previous franchise names are acceptable.
- For player and team cell, the player must have played at least one game (in the regular season or playoffs) for that team.

Here are some tips and tricks for playing Immaculate Grid Football:
- Use your knowledge of football to make educated guesses.
- If you need additional help, consider using resources like Pro Football Reference's franchise matching tool or award section.
- Think about connections between teams, such as coaches who frequently bring players they know from one franchise to another.
- Keep in mind interesting facts like kicker Jose Cortez being the only player in NFL history to play for all four division teams in the NFC East during the early 2000s.
