For the 5* rating I would have expected a little more logic - or am I just having a dumb morning.

I solved for to give one star.
spoiler: 1. row 2-4 18-21, 7. 3-4 17-19, 8. 2 and 19, 11. 1-2 7 12 19-22, 13. 1 4 6 8 11 13 15 19-25, 25. 3-8.

Thanks for your help, Rovi avcisi, couldn't solve it without the spoiler :-)

I too needed the spoiler, thank you.

It was almost completely logical. About 90% of it can be figured out solely with trial and error logic before you have to make an educated guess; which all you need is to place R19C17, and then the remainder of the face is also logical. Thanks for the challenge!

This was not logical at all. These puzzle are not meant to be solved by using trial and error. Please check your puzzles before submitting them.

Mostly logical. Just the last few squares in the middle are ambiguous. Thank you for the puzzle!
