All the rules and strategies of Sudoku "search to nine" apply: diagonal distances must be projected to an horizontal line, and can point to any nine in that diagonal. (Like in this puzzle)
Rephrasing those rules; if there is a 1 on an arrow, the cell immediately adiacent must be a 9. If there is a 2 on an arrow, the second closest cell must be a 9 ... Etc.
White dots divide cells with consecutive numbers; not all kropki dots are given.
The cages drawn can be of several possible types listed below! (Every cage belongs to one type on the list - you must find out which type each cage is).
One cage is a renban group (so, it contains consecutive numbers in ANY possible order; like 57869) - EXCEPT the biggest number of the group is located at the center of the L.
Two cages are identical, with only rotations but not reflections allowed.
Two cages contain palindrome sequences.
Solution code: ROW 4, THEN ROW 9

@SirWoezel That is what I thought too.

I think if there is a 3 on an arrow, there will be a 9 in the direction of the arrow three cells away. Though I have to agree it's pretty unclear what is meant by 'must be projected to a horizontal line'.

I do understand that part, I don't get the diagonal thing.
PS palindrome is with an i

I don't understand the first rule
