Post SU DOKU

You must put a number, from 1 to 9, in each empty box. Each number must appear once in each horizontal row, as well as in each vertical column and in each of the 3-by-3 grids.

Super Su Doku, inside, multiplies the challenge — and your enjoyment. For that one, put a number from 1 to 12 in each empty box, making sure each number appears once in each horizontal row, as well as in each vertical column and in each of the 3by-4 grids.
