How to Solve a Shadedoku Puzzle

Each puzzle follows the basic rules of Sudoku: the numbers 1 through 9 must appear once (and once only) in each column, row and subgrid. But there are 9 additional squares in each puzzle that are shaded - the numbers 1 through 9 must appear once (and only once) in each of those squares as well. Each puzzle has only one unique solution, and each can be solved using pure logic. Good luck!
