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

Amazing series! This one is decidedly easier than many of the previous entries, but no less fun!

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. :)
