Absolutely delightful! A very cool (if slightly tricky) break in, and then an amazingly smooth solve across the grid. Beautiful work!

I love this series! I made a stupid Maths error in quite an early stage and only found it when the puzzle was almost finished, so I had to almost restart it. Still it was a interesting and smooth puzzle! I'm looking forward to 27-killer sudoku!

**
Thank you for your comment, samuel1997! It is great to hear you enjoy the series. Considering 27-cages, that puzzle already exists. It is a collab with Mellowrobinson called "The 27 Club". So I might try setting one with 28s next. :)
Kind regards, sujoyku
