A GREAT MANY RULES...variant sudoku (2-3/5 difficulty)

A many great rules? Wowza, this was a really interesting one simply because of the number of rule sets to play with. There was one REALLY challenging part near the end, i'm not sure if it was the intended solve path, but wow was it great when i saw it. I wouldn't call this one easy, if you aren't familiar with all of these rule sets, but it's still achievable if you put in the time. It's called "spot on the dot", by 99%Sneaky who is a pretty well known sudoku author. link to puzzle: https://sudokupad.app/vleb7el1fw
