Qarpet Beater

(Published on 14. November 2020, 14:59 by Qodec)

Disjoint killer sudoku, and a tribute to Botaku and his Carpet Beater puzzle. Spelled with a 'Q' because the puzzle also looks like a 'Q'.

  • Normal sudoku rules apply.
  • Disjoint groups: Digits cannot appear in the same position in different box regions. For example, r1c1 (the cell in row 1, column 1) and r4c4 cannot contain the same digit.
  • Killer cages: An area in the grid surrounded by a dashed line is a 'killer cage'. The number in the upper left corner of a cage is the sum of the digits within that cage. Digits cannot repeat within a cage.
  • Little killers: Digits along diagonals indicated by arrows outside the grid must sum to the given number at that arrow.

The two single-cell cages in box 9 are for decoration.

You can play this puzzle online using f-puzzles: https://f-puzzles.com/?id=y3xs5r4l.

Good luck!

Solution code: The 9 digits in row 4 from left to right, followed by the 9 digits in row 6 from left to right, no spaces, for example: 123456789123456789
