The aim of Immaculate Grid is to select a player for each cell who matches the criteria for that cell's row and column. In the image below from the baseball version of the game, the cell in the top left corner is asking for a player who played in the majors for both the Pittsburgh Pirates and the Chicago White Sox. For the top right cell you would need to think of a player who won the Silver Slugger in a season that they played with the Pirates.

To see both the general rules for the game and specific rules for each category, click the "Rules" link above the grid.

Clicking the category headers in the game will also display the rule for that particular category.

And clicking on the team logos will show the history for that franchise, including any former names for the team.

In addition to baseball, Immaculate Grid is available for Men's and Women's Basketball, Football, Hockey and Soccer. Links to these games are found directly above the grid, and a Rules link also appears above the grid for each of those games.
