I built this puzzle trying to learn how to create set equivalence theory (SET) puzzles. Sadly, although this puzzle is unique, it is beyond my own solving skill. For those of you with better advanced sudoku skills, I hope you enjoy this test puzzle. Any feedback would be sincerely appreciated (and much needed)!

• Normal Sudoku Rules: Fill each row, column, and 3x3 box with the digits 1-9 once each.
• Arrows: The sum of the digits along an arrow is equal to the digit in the connected circle. Digits along an arrow can repeat if allowed by other rules.
• Killer Cages: Digits in cages must not repeat and must sum to the number in the upper left corner of the cage (if present).
• X: Cells separated by X must sum to 10.
