It is Scojo's birthday 🎊 🥳 🎊
...and also it is the anniversary of his weekly puzzle prompts!
There will be snacks for everybody! 😉 🍰 🥨 🍩 🍦
- Normal sudoku rules apply.
- Place nine copycat cells on the grid so there's exactly one copycat cell in each row, column and box. Digits may not repeat in copycat cells. The value of a copycat cell is equal to the digit in the cell that is a 180° rotation around the the center of the grid (for example, if r7c9 is a copycat cell, then its value is the digit in r3c1). The value of a non-copycat cell is equal to the digit in it.
- Cells joined by a black dot have values in 1:2 ratio.
- Cells joined by a white dot have consecutive values.
- Not all possible dots are given.
Solution code: Digits in row 6, followed by the values of all copycat cells, left to right.

This was an excellent copycat puzzle, definitely better than my own execution of the same ruleset! And a great birthday gift too!

Thank you for that! Hard but very nice and relatively smooth considering the difficulty rating, took me just under an hour.
