My first ever Sudoku puzzle! Starting off with a modest 6x6 for now, but in the future, I hope to eventually be able to expand to 9x9s. In the meantime, I hope you enjoy it!
Hint for the break-in: the clue is in the title.
Rules: Normal 6x6 arrow Sudoku rules apply.
(Place the digits 1-6 once each in every row, column, and 2x3 box. Digits along an arrow sum to the digit in the attached circle. Digits along an arrow may repeat if allowed by other rules.)
Solution code: Row 6 (left to right)

The SET theory and Phistomefel ring were really interesting to learn about, but even after an extensive deep-dive I found this puzzle extremely hard to solve. This is definitely not a 2*.

I don't understand the hint. I bifurcated heavily hoping that the contradictions would show me something, but I found nothing. What did I miss?
rkm_sts: It requires an advanced strategy that is seen in a good number of other Sudoku puzzles. In case you're not familiar with the technique, here's a video explaining a rather famous example: https://youtu.be/pezlnN4X52g
