Ouch My Poor Poor Brain: Sudoku At Its Maddest!!

** TODAY'S PUZZLE ** What a ruleset... It's not that it's difficult to understand but it's quite hard to know what on Earth to do with it!! Oddlyeven decides he will break our collective brains with this one. It's called Yin Yang Doubler Uniqueness but it could simply be called 'AAAAGGGHHHH'!!! Play the puzzle at the links below: https://sudokupad.app/yl0n45rfll Rules: Normal sudoku rules apply. Yin Yang Doublers: Shade some cells in the grid such that all shaded cells are orthoganally connected and all unshaded cells are orthogonally connected. No 2x2 may be all shaded or all unshaded. A shaded cell has a value equal to twice its digit. An unshaded cell has a value equal to twice its digit minus one (double the digit first, then subtract one). Uniqueness: On each of the constraints below, values do not repeat anywhere in the puzzle. For example, if there is a shaded 5 (value 10) on a renban, shaded 5 can't appear anywhere else on a renban, but unshaded 5 could because it has a value of 9. Renban: Values on a purple line form a set of consecutive numbers with no repeats. Arrows: Values along an arrow sum the value in that arrow's circle. X: Two cells joined by an X have values that sum to 10. Black Dots: Two cells joined by a black dot have values where one is double the other.
