I checked the sudokus and both are not solvable in my opinion.
In the first one it is easy to see that in the block on the bottom-right side the 7 has to be placed in column 7 row 8. Then the 8 has only two possibilities at column 9 row 7 or column 9 row 8. On both places there is no adjacent 7 possible, so this rule breaks.
The second one for sure is not unique, because you can choose with which odd or even number you fill in to the given "E" and "O". Also the orientation of the blocks is not clear. I tried to solve it, but it got no valid solution mostly because of the knight's move.
