PDF<\/a><\/p>\n

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

Theme:<\/b> Factor Fiction<\/p>\n

Author\/Opus:<\/b> This is the 44th 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). For every pair of adjacent values connected by a line, one number is a multiple or a factor of the other. (For example, if R4C1 were 3, then R4C2 which is connected to R4C1 could be 1, 6, or 9, because 1 is a factor of 3, and 6 and 9 are multiples of 3. In this specific grid, it is not possible for a number to be adjacent to itself from Sudoku rules.)<\/p>\n

GAS Time Standards (highlight to view):<\/b> Two party hats (\ud83c\udfa9\ud83e\udd73): 7:30<\/span>; One party hat (\ud83e\udd73): 16:00<\/span>. All other solvers earn a \ud83e\udd95: Boding Baurutitan<\/span>.<\/p>\n

Thomas Hits the GAS (highlight to view):<\/b> 3:13<\/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
