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

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

Theme:<\/b> Not an Arrow Sudoku<\/p>\n

Author\/Opus:<\/b> This is the 121st puzzle from Clover, 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). Some arrow shapes are in the grid; the sum of the numbers along the path of each arrow must equal the number in the circled cell. Also, along each arrow shape, the numbers (including the circled cell) alternate in parity. (For instance, 9 = 2 + 7 and 9 = 4 + 3 + 2 are valid sequences, but 9 = 7 + 2 and 9 = 1 + 3 + 5 are not.)<\/p>\n

GAS Time Standards (highlight to view):<\/b> Two party hats (\ud83c\udfa9\ud83e\udd73): 6:30<\/span>; One party hat (\ud83e\udd73): 12:00<\/span>. All other solvers earn a \ud83e\udd95: forgot-a-constraint Fabrosaurus<\/span>.<\/p>\n

Thomas Hits the GAS (highlight to view): <\/b> 2:13<\/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
