Sandwich Sudoku - Club Sandwich
(Published on 31. December 2020, 15:20 by DiMono)
Standard sudoku rules apply.
Clues outside the grid are sandwich clues, but there are THREE crust digits (to be identified by the solver), and the clue indicates the combined sum of all three available sandwiches. All rows and columns use the same crust digits.
For example, if the crust digits are 2,5,8, then the sandwich sum for the row 123456789 would be:
(3+4) + (6+7) + (3+4+5+6+7) = 7 + 13 + 25 = 45Solve on f-puzzles
Solution code: Row 4, Row 7

For those unfamiliar with sandwich sudoku, standard sandwich rules are that clues outside the grid indicate the sum of the digits placed between 1 and 9 in the row or column. 1 and 9 are the "crust" of the sandwich, and the digits between the crust are the "filling". For this puzzle, there are three crust digits, giving three possible sandwich sums, and the clues are the sum of all three sandwiches.
