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

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

Theme:<\/b> Learning to Fly<\/p>\n

Author\/Opus:<\/b> This is the 34th 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 each line, the numbers in each pair of cells an equal distance away from the center of the line must sum up to the value in the central cell of the line. (In this puzzle, the lines that cross go straight through those cells; this means, for example, R6C2 + R6C4 = R6C3 from the Zipper Lines rule.)<\/p>\n

GAS Time Standards (highlight to view):<\/b> Two party hats (\ud83c\udfa9\ud83e\udd73): 7:00<\/span>; One party hat (\ud83e\udd73): 14:00<\/span>. All other solvers earn a \ud83e\udd95: Examined Elosaurus<\/span>.<\/p>\n

Thomas Hits the GAS (highlight to view):<\/b> 3:24<\/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
