Sudoku puzzles disjoint groups (Su Doku)

My database includes 656 puzzles for the moment and I'm constantly generating more.

Rules: Fill in the grid so that every row, every column, and every 4x4 box contains the digits 1 through 16. The cells with the same color must also contain the digits 1 through 16. There is only 1 solution for each puzzle.
