X-Sums Sandwich Sudoku

(Eingestellt am 12. Oktober 2020, 09:37 Uhr von RobK)

Solve on F-Puzzles

Rules: Normal Sudoku rules apply. Also, numbers/dashes outside the grid mean that the sum of the digits between 1 and 9 in that row/column (Sandwich clues) equals the sum of the first 'n' digits in that row/column from that direction where 'n' is the first digit of that row/column (X-Sum clues). One of these sum totals is given. The relevant 'n' is different in each of the X-Sum clues.

Good luck and have fun!

Lösungscode: The first row of the finished grid, from left to right with no spaces or commas, then the final row of the finished grid, also left to right. So 18 digits in total.

Lovely puzzle! The fact that the first digit of the x-sum clues are different provided some nice logic. I really enjoyed the hybrid x-sum/sandwich clues :-)
