Rules

• Normal sudoku rules apply.
• Draw a single one-cell-wide path through the grid. The path does not branch or touch itself orthogonally, but may touch itself diagonally. This path is a ten line: the line is divided up into groups of consecutive cells, each of which sums to ten.
• Clues outside the grid are j-sums clues. They give the sum(s) of groups of contiguous ten-line cells within their row or column. The sums within a clue appear in the correct order left to right or top to bottom. Where given, clues are complete, with the caveat that a ... stands for zero or more omitted clues.
• A ? clue is an unspecified single digit number, and a ?? clue is an unspecified double digit number (that is, no leading zero).

Solve in Sudokupad.
