Solution Guide:

I make solution guides for most of my puzzles, usually as a sanity check for myself, but I have never included one before. This puzzle is long past being widely seen, so for any intrepid puzzlers who stumble on this and thinks to themselves, "this puzzle is impossible" (as one person told me), I felt like including my guide. The break-in is easily my most convoluted, complicated, and difficult, and for this I apologize. Referencing a quote from a fictional philosopher, I was so preoccupied with whether or not I could make this puzzle, I didn't stop to think if I should. By the time you get the first digit, the rest of the puzzle should fall into place relatively easily. The link to my document is below

Rules:

Regular sudoku rules:

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

Difference of sums:

1. The difference between the sum of the Cyan cells (C) and the sum of the purple cells (P) is 8. It is up to you to determine which of the two color sets has the larger sum

2. The difference between the sum of the Red cells (R) and the sum of the orange cells (O) is 7. It is up to you to determine which of the two color sets has the larger sum

Rotated cells:

The grey cells (G) have identical pairs rotated 180° around the center digit. (r6c3 = r4c7, r7c4 = r3c6)

Region Sum Lines:

Box borders divide each blue line into segments with the same sum.

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.

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