Rules:
Normal sudoku rules apply.
Killer sudoku: In cages digits must not be repeated and must add up to the total given in the top left corner of the cage.
Jumping digits: A digit in a purple cell is a "jumping" digit. At a distance of exactly x cells from this digit, there must be another cage in at least one orthogonal direction that contains the same digit. x corresponds to the jumping digit. A jump that would go beyond the edge of the grid continues on the other side of the grid.
Example:
The 3 can jump only into the green cage, the 4 only into the yellow one.
Here is another puzzle with the jumping digit rule, in which the cage totals need to be determined by yourself: Jumping Digits - Upstairs
Solution code: column 9 (top to bottom) followed by row 9 (left to right) (18 digits)
