Also, divide each line into subsections so that each cell on the line belongs to exactly one subsection, and each subsection contains exactly one number clue. Each subsection acts as a Killer cage: values in a subsection cannot repeat and must sum to the total given by that subsection\u2019s number clue. (Numbers *can* repeat on a line if allowed by other rules, as long as those numbers are in different subsections.)<\/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;\">10:00<\/span>; One party hat (\ud83e\udd73): <span style=\"color: white; background-color: white;\">20:00<\/span>.
