- Normal sudoku rules apply.
- Double Arrows : The sum of the digits on the line must equal the sum of the digits in its end circles. Digits may repeat on double arrows if allowed by other rules.
- Sandwich : A number outside the grid indicates the sum of the numbers between 1 and 9 in that row or column.
- Disjoint Groups : Digits in the same relative position within boxes must be different.

Amazing puzzle! Hard to spot where to look next sometimes, so it took me quite a while. Thank you so much!

Glad you enjoyed the puzzle and many thanks for the kind remarks. This puzzle went through several iterations and it was quite challenging to get the right ruleset, but I think these specific constraints work really well together. I will admit there are some tricky points, but all deductions should be fair.

Example for double arrows:
4 and 5 (4+5=9) in the circles would mean the digits between those two circles must also sum to 9.

I don‘t understand the double arrows part of the rule set.

As Raumplaner specified, the digits on a line will sum to the same total as the circles on both ends.
Example: (7)-9-6-(8)
I think this is a ruleset that was introduced by zetamath last year, with his puzzle Diamond, which can be found here : https://logic-masters.de/Raetselportal/Raetsel/zeigen.php?id=0007D3

Fascinating logic - very original and great interactions.

Thanks for kind words and the solve. Really appreciate you and the gang at skunkworks for testing and brainstorming, as this one took quite a while to come together.
