Each player rolls 2 dice and selects an available box in the table by creating an ordered pair with the two numbers rolled.

Each player places a counter on their selected box.

Each player finds the Greatest Common Factor for the numbers in their box.

The player with the larger Greatest Common Factor keeps their colored counter in that box. The other player removes their counter.

If the Greatest Common Factors are equal, both players remove their counters.

If no boxes are available on the game board after a player rolls, then they roll again until they are able to select one.

The game continues until one player gets four boxes in a row, vertically, horizontally, or diagonally.
