Solitary Nines

• Normal sudoku rules apply.
• Colourful Dots - Cells on either side of purple dots sum to 9 and cells on either side of red dots sum to 6. All dots are not necessarily given.
• Kropki Dots - Cells on either side of a white dot must be consecutive.
• Solitary Nines - 9s cannot be orthogonally adjacent to 8s
• Honorary Nines - Given 6s are treated as 9s for the Solitary Nines rule

It might only be 1 star for difficulty but my testers thought it might just be into 2 stars so I'll set it to that to start with. Enjoy!
