(Eingestellt am 14. August 2025, 11:40 Uhr von Crusader175)
Another puzzle exploring Clock Faces constraint, and I thought it might be fun to combine it with the Dutch Flat Mates. Hope you enjoy solving the puzzle, and if you like it, check out my other Clock Faces Puzzles!
Rules:
Normal sudoku rules apply.
Dutch Flat Mates: Every 5 in the grid must have a 1 directly above it or a 9 directly below it. It may have both, but it doesn't need both.
Clock Faces: Four digits around a circle are placed in an increasing order starting from one of the four cells and going clockwise (white circle) or going anticlockwise (black circle).
X Pairs: Cells separated by an X sum to 10. Not all X's are given.

I solved it by noticing a pattern, but without actually proving that the pattern is the only way the digits can be arranged.
So, Simon would not approve, I guess.
But a very nice puzzle.
Reply: I put the clock faces logic explanation in the hidden comment. Thank you for solving! (The document has been updated and I decided to make it publicly available)

This is a very nice special episode to the DFM series. Not that difficult once you understand the constraint.
Reply: Thank you da-hans! I tried to make it not too difficult, focusing on showcasing the clock faces logic and the interaction with DFM.
