Rules:

Normal sudoku rules apply.

Digits separated by a white dot must differ by the indicated number. Digits separated by a black dot must have a 1:2 ratio.

The digit in the big circle must be equal to the sum of the digit directly above and the digit directly below it.

Digits along a purple line are a set of consecutive, non-repeating digits in any order. The T-shape acts as a single renban.

The blue network forms a tree of dominos. Every line piece on the tree joining two cells must contain a unique domino, read from left to right or top to bottom. Note that dominos may overlap and that ab and ba are two unique dominos.
