Players roll two dice, and may keep none, one, or both of them. After two rolls, the number must be entered on the scoresheet in one of sixteen cells. A '7' is entered as an 'X' and prohibits scoring in that row or column. A '2' OR '12' is a wild roll, and any number may be entered. After all the cells are filled, points are scored according to the combination of numbers in each roll, column, and diagonal. The player with the most points wins the game. - BoardGameGeek
