Each of the 25 blocks of four letters shown above can be rotated about its center, either 90^o clockwise, 90^o anti-clockwise or 180^o. When all the blocks are in their correct orientations, all the ten rows and columns contain the letters A to J exactly once.

Sixteen of the blocks shown above are not in their correct orientations. Which 16 out of the 25 blocks have been rotated and in which direction(s)?

This puzzle about rotating the blocks to achieve a perfect alignment of letters is quite a brain teaser! To tackle it effectively, you'll need to analyze each block's current position and determine the necessary rotations.
