Rules:
Normal Sudoku rules apply.
Shaded areas of the same size, shape, and color contain the same digits in the same arrangements.
Cells separated by a white dot contain consecutive digits. In cells separated by a black dot, one digit is double the other. Not all possible dots are given.
Estimated difficulty: 1 out of 5
