I'm keeping this puzzle up for posterity, but for a better (in my opinion) implementation of the same idea, please check out Seven of Nine.

Rules
  • Standard sudoku rules apply
  • Each 7-cell cage has a different sum and is adjacent to a 2-cell cage whose digits when read left-to-right or top-down provide the sum of the larger cage. Ex: A 7-cell cage with a sum of 31 must be adjacent to a 2-cell cage with the digits 3-1.
  • Digits in cages cannot repeat.
  • Gray lines are palindromes: digits along them read the same way in either direction.
  • The cells separated by a white dot differ by 1

NOTE: The break-in isn't especially tough, but you will quickly reach a point where it becomes difficult/impossible to proceed without making an interesting realization about the nature of the different cages. The intended solution path doesn't require any more arithmetic than would be expected in an average killer/little killer puzzle, and you shouldn't need to mentally iterate through lots of permutations of digits for the large cages.

Solution code: Column 1 + Row 3

Fantastic puzzle, with a great setup. Really pretty hard, even once I twigged what your hint told me; thanks for that!
