Slightly different version of this puzzle because I can't stop tinkering.

Note:

I was reviewing an older puzzle of mine, The Gordian Knot, and I realized with some minor changes, I could re-work how the puzzle plays. This experiment worked better than I was expecting. The original puzzle was designed to be incredibly difficult if you didn't know it's secret and relatively easy if you did. And I made the secret non-intuitive. It could easily be called an exercise in frustration. This puzzle, on the other hand, requires no secret to solve and flows very differently than the original version. I suspect this version will be more enjoyable to play, while maintaining a certain amount of difficulty.

Rules:

Regular sudoku rules:

Place the digits 1-9 in every row, column, and box

Rotated cells:

The grey cells have identical pairs rotated 180° around the center digit. (r6c3 = r4c7, r7c4 = r3c6). To help clarify these paired cells, they each have a Greek letter in the corner to help identify pairs. R3c6 and r7c4 both have the letter β, which indicates they have the same digit.

Region Sum Lines:

Box borders divide each blue line into segments with the same sum. Each X-shape made by the region sum lines are comprised of two separate region sum lines

White Kropki Dots:

White dots placed between two cells indicate the digits in those cells are consecutive. Not all dots are given.

Killer Cages:

Digits in cages must sum to the number in the upper left corner of the cage.

Anti-Knight:

Cells that are a knight's move (in chess) apart must not contain the same digit.
