Numbers cannot repeat on the marked diagonals. Also, an arithmetic series must be formed along each line so that numbers in adjacent cells have the same difference. Different lines may have different common differences. (For example, sequence line could be 1-2-3-4 (difference of 1), 1-5-9 (difference of 4), or even 5-5-5 (difference of 0) if it obeys other Sudoku rules.) Different shades of gray are used to help show 3- and 4-cell lines.<\/p>\n<p><b>GAS Time Standards (highlight to view):<\/b> Two party hats (\ud83c\udfa9\ud83e\udd73): <span style='color: white;background-color: white'>7:30<\/span>; One party hat (\ud83e\udd73): <span style='color: white;background-color: white'>14:00<\/span>.
