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

Author\/Opus:<\/b> This is the 103rd puzzle from Bill Murphy, 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). A cell containing a diamond is part of a group of numbers of the same parity connected by edges, and the number inside the diamond indicates how many numbers of the same parity (including itself) form this group. (For example, a diamond containing a 2 must be connected by its edges to only one other even number besides itself; that is, all other edge neighbors of these two numbers must be odd.)<\/p>\n

GAS Time Standards (highlight to view):<\/b> Two party hats (\ud83c\udfa9\ud83e\udd73): 9:00<\/span>; One party hat (\ud83e\udd73): 17:00<\/span>. All other solvers earn a \ud83e\udd95: Handsome Jaxartosaurus<\/span>.<\/p>\n

Thomas Hits the GAS (highlight to view): <\/b> 4:33<\/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>; solving video with explanation to be added later from GAS team.<\/p>\n
