I agree that the 8x8 is a little bit harder than this one. But it was a pleasure to solve all of them

Thank you for the nice series, BlueToast001! I also found the 8x8 to be significantly harder. This 9x9 was smooth as silk. Very nice construction!

"You completed the hardest in the sequel"
No, I did not, had to skip 3, way harder than this one :P
- OMG... I intending on it being the hardest and after testing I realised that was not the case. I DID change that but must've forgotten to update the sudokupad link when uploading. My apologies LOL

This was my favorite, I think. The branching thermos were fun.
I really enjoyed the idea of escalating sizes built around the same variant. This pack's main weakness is that the 8x8 puzzle is significantly harder than all the others, including the 9x9. It's a jarring change to run into, and leaves the 9x9 feeling more like an anticlimax than a finale.
