Today is the ten-year anniversary of the first real puzzle I created. To celebrate, here is an anniversary puzzle that combines three of my early designs into one sudoku. Solution and more at: https://quadratablog.blogspot.com/2022/ ... ation.html
I congratulate you on persistence in creating wonderful puzzles. I mean I’ve probably solved all your ones published here (except those with chess pieces I fear 
). Many thanks… ![[thumbup]](./images/smilies/msp_thumbup.gif "ThumpUp")
To Ten Year Anniversary Puzzle: Not super hard, but took some time to find a ‘weak point’, which was for me the nonet 9. I’d also like to say I wasn’t sure whether 1 is an allowed divisor or not (of course, it should be); nonet 5 + r8c6 cell gave me a quite quick answer.
