Rules:

Irregular Sudoku: Place the digits 1-9 once each in every row, column, and outlined region.

XV: An X between two cells indicates that the digits in those cells sum to 10. A V between two cells indicates that the digits in those cells sum to 5. Cells without an X or V between them must not sum to 5 or 10.

Japanese Sums: The colored circles outside the grid indicate the order of runs of contiguous cells found in that row or column that must be shaded the color of the clue. The number in the clue indicates the sum of the cells in the run. There must be at least one unshaded cell between runs of the same color, though there is no need between runs of differing colors. A '?' as a clue represents any unknown total. All runs are given.
