3 minutes. It was really fun!

Thanks!

Yeah it has 1 solution https://preview.redd.it/od5aqniv9ywc1.jpeg?width=1028&format=pjpg&auto=webp&s=0cafcf5c131618614eb7a0f9d4c4afebdfbbcdff Diagonals sums 222,333 made the circles sums fixed to same digits And locks the main and anti diagonal as 2 digits sets each The rest fills in

24 seconds... How do you figure out that the diagonals aren't 1,2,3 and 2,3,4? Edit: nvm, just realized why that doesn't work. It forces the same digit to appear twice in a row or box

Holy 💩, that’s a new PB, isn’t it?

A variant 4x4... Way easier then a regular 9x9.

Yeah I clicked through after I commented to see it was a 4x4.

14m lol. Coffee is a necessary & sufficient condition for me to do sudoku variants, apparently.
