Normal sudoku rules apply.
A circled digit indicates that the cell at that position in the row is a 5 7 or 9. That is to say if, e.g., r4c2 is an 8, then r4c8 is a 5 7 or 9.
Black dots indicate the given cells have a ratio of 2:1. Not all black dots are necessarily given.

Interesting, but boy were there many places where my logic lead me wrong.

Very intricate.

Lovely puzzle - I really struggled with it, but solely because I kept confusing myself with the rules (should have paid more attention!) - took a couple of restarts, but credit to the setter it was straightforward if done properly!

Solved nicely once I got my head wrapped around it... which sadly took a while. Great puzzle!

This was a lot of fun to solve once I wrapped my head around the ruleset and the constraints played very well together!

Very nice! I found it pretty hard to get started, but once you wrap your head around the constraint, it flows very nicely :^)

Wow. That was very funny. I've never seen that restriction before, and found a lot of fun and new logic! Spent some time just wrapping my brain around how to think about it to get started, but when you got into the logic, it went quit smoothly :-) Thanks a lot!
