This awkward-looking puzzle is as simple as clockwork to solve. Put a 5 above the 55 in the top row and another 5 before the 30 in the first column. Then write what number the big hand is pointing to when it is 55 minutes after the hour and so forth until you have written the numbers from 1 to 12 in both the first column and the top row. (You will have to figure out what numbers go with the column and row without clues.)
