Normal Sudoku rules apply. Place the digits 1-9 exactly once in every row, column, and 3x3 box.
X-Sums: Values outside of the grid are X-Sums clues. The clue sums the first X digits from the clue, where X is the closest digit to the clue. X-sums clues may be one or two digits. '?' represents a single digit.
Clones: Colored caged shapes in the grid are Clones. The same digits appear in the same relative positions within each Clone.
Solution code: All digits in Column 1, followed by row 6 (19 digits)
