or solve online<\/a> (using SudokuPad)<\/p>\n

Theme:<\/b> The Waiting<\/p>\n

Author\/Opus:<\/b> This is the 36th puzzle from Philip Newman, part of the Genuinely Approachable Sudoku (GAS<\/a>) team.<\/p>\n

Rules:<\/b> Standard Sudoku rules (insert a number from 1 to 9 into each cell so that no number repeats in any row, column, or bold region). Along each line, the numbers in every region it passes through have the same sum. (In this puzzle, for example, R3C5 + R3C6 = R4C6 = R4C7 + R5C7.)<\/p>\n

GAS Time Standards (highlight to view):<\/b> Two party hats (\ud83c\udfa9\ud83e\udd73): 8:30<\/span>; One party hat (\ud83e\udd73): 17:00<\/span>. All other solvers earn a \ud83e\udd95: Humane Haplocanthus<\/span>.<\/p>\n

Thomas Hits the GAS (highlight to view):<\/b> 5:29<\/span>, with SudokuPad replay file<\/a> shared as a download for now (requires loading via settings menu with improvements expected before people should use this regularly).<\/p>\n

Solution:<\/b> PDF<\/a> and solving video<\/a> with explanation from GAS team.<\/p>\n
