Today's Video:

Still a handful of gUBBLOR's puzzles to play, but this one stood out to me, aside from its high rating, it uses a new variant I don't believe I have featured or played before.

Equality Cages 136: Equally different by gUBBLOR https://link.sudoku-sleuth.com/EqualityCages136

Rules:

Normal Sudoku rules apply. Place the digits 1 through 9 in each empty cell. Digits must not repeat within the same row, column, or box.

Equality cages: Cages must have an equal number of low (1,2,3,4) and high (6,7,8,9) digits AND an equal number of even (2,4,6,8) and odd (1,3,7,9) digits. Equality cages can never contain 5. Digits may not repeat in a cage.

Same difference lines: Each pair of adjacent digits on one the lines has the same difference. All lines MUST have unique "difference values".

Kropki dots: A black dot between cells indicates cell values with a 2:1 ratio. A white dot between cells indicates cells with consecutive values. Not all dots are shown.

V: Adjacent cells connected with a V must sum to 5. Not all V's are shown.
