Theme:<\/b> Home on the Range<\/p>\n

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

Rules:<\/b> Standard Sudoku<\/a> rules (insert a number from 1 to 9 into each cell so that no number repeats in any row, column, or bold region). Clues outside the grid indicate the sum of the numbers from position A to position B (inclusive) in that row or column, where A and B are the first two numbers from the direction of the clue, regardless of which number is larger. For instance, if the rightmost two numbers in row 7 were 5 and 7 (or 7 and 5), then the sum of the numbers in the 5th, 6th, and 7th positions from the right in that row would equal 6, the value of the outside clue.<\/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: wide-ranging Willinakaqe<\/span>.<\/p>\n

Thomas Hits the GAS (highlight to view):<\/b> 1:50<\/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
