A knight of the seven kingdoms

(Published on 23. November 2025, 07:31 by ivaylagergova)

Normal Sudoku rules apply: Each row, column, and 3×3 box must contain the digits 1–9 exactly once.

Cells separated by a knight’s move in chess cannot have the same digit.

The digits in a circle indicate which numbers appear in the four surrounding cells.

The anti knight logic here was really good and hard to find. It was harder because I believed the puzzle was 2 stars and that I had missed something more obvious.

Pretty puzzle ! Fast start but stuck at mi-game (took me 2 days RIP)
Some deductions were very cool, this puzzle exploit well anti-knight constraints !!
Thank you for setting

Nice puzzle. The solve path gets quite narrow at some points, especially in the midgame. If you are looking in the right places, this is a 1.5, but if not it can be 3-4. Anyway, I had fun, thank you for setting!

Fairly easy start but got much tougher midway through. Some challenging and surprising anti knight discoveries. Thanks I enjoyed it!

Wow maybe I missed something (like some SET poimt), but I found it much harder than 2 stars. I ended up solving in just over two hours of rather difficult scanning.
