What a clever setting. I'd give it 3* personally. Seemed impossibly hard at first until the right thing clicked, then completely linear from that point forward.

How on earth did you come up with this? Really cool puzzle. A bit mind-bending but not quite as hard as it first looked, and finished very smoothly.
Definitely use the note space!

Very interesting ruleset. Requires a lot of work after the first 2 digits as mentioned elsewhere. Would also recommend the note space version - I felt cross eyed even with it!

That was some very nice logic. Not easy but had a great time solving. Thanks!

Lovely puzzle. I solved it with note space, which I would very much recommend, as it makes the constraints a lot easier to visualize.
After immediately placing the first two digits, progress was slow for a bit until I found the right questions to ask.
