Japanese 159

(Eingestellt am 16. Dezember 2021, 12:44 Uhr von HawkAvatar)


  • Normal Sudoku rules apply

  • Japanese sums: Shade some cells such that the clues outside the grid indicate the sums of the digits in contiguous blocks of shaded cells in the row/column. Blocks have to be separated by at least one unshaded cell.

  • Twisted 159: Digits in shaded cells in column c indicate the column in which the digit c appears in that row.

    Example: if r3c3 were a shaded cell with a 6 in it, then r3c6 would be a 3

  • Negative constraint: All cells that satisfy the twisted 159 rule are shaded


Penpa (Answer check enabled for entered digits, ignores shading)

Lösungscode: Column 7 followed by row 8 (18 digits)

Very approachable and Beautiful, just beautiful. I loved how it came together, plus some sharp negative 159 constraint deductions to resolve it in the end.
