Normal Sudoku rules apply.
Weird Modular Triplets: For every set of three adjecent digits along a pink line, two of the digits are congruent modulo the third digit.
For example: 238 is a valid triplet because
2mod(3) = 2 = 8mod(3)
467 however is not a valid triplet since
4mod(7) = 4 =/= 6 = 6mod(7)
4mod(6) = 4 =/= 1 = 7mod(6)
6mod(4) = 2 =/= 3 = 7mod(4)
Killer Cages: Digits in a cage sum to the number in the top left corner of the cage.
