Normal Sudoku rules apply.

The Rules:

1. Nonogram : The clues above and to the left of the grid show the number of consecutive unshaded cells in that row or column. Consecutive runs of unshaded cells must have at least one shaded cell between them. The (?)'s are unknown values and can be any number from 1 to 9.
2. Numbers below and to the right of the grid (Yellow and Red cells) are the sums of the digits in the shaded cells in that row or column.
3. The red clues mean that the digits in shaded cells for that row or column will form a prime number in reading order (left to right or top to bottom). All possible red clues are given.
4. The green cell with an X is a Sandwich Clue. The value of X is the sum of the digits in the shaded cells in that column. It is also the sum of digits between 1 and 9 in that column.
