Today's Video:

Another exceptional puzzle from The Bard. Whilst the ruleset may seem intimidating at first, I usually struggle with puzzles that allow "negative" digits, the construction of this puzzles allows it to be incredibly smooth.

Well other than some Sudoku shenanigans for me at the end...

Rules:

Normal Sudoku Rules Apply. Place the digits 1-9 in each row, column, and box.

Yin Yang: shade some cells so that all shaded and unshaded cells form 2 form orthogonally connected areas such that no 2x2 area is entirely shaded or unshaded, and all the digits values in the shaded area are negative values.

Killer Cages: VALUES in cages add up to the total in the corner.

Kropki Dots: consecutive VALUES between 2 cells are indicated by a white dot, not all dots are given.
