As this puzzle appears to be causing a lot of problems, here's a hint;

This is a killer but there are no cage totals. However, each cage has a number in it so that number must be related to the cage total. If you look at the two cell cage with a 5 in it, if the other number is a 9, the cage total would be 14. 1+4=5. The cages with 7 in them must be either 16/25/34 or 43. If there are only three cells, the cage must be 16.

A killer must have cage totals. This one didn't have any. However, there was one number given in each cage. Therefore it is logical to assume that this given number must relate somehow to the cage total.

If you add the numbers 1/2/3/4/6/7/8/9 to the 5 in the 2 cell cage, the only logical number it can be is 9 because 14 is 1+4=5 - a definite connection. The other numbers have no logical connection.

(Well, I thought it was pretty logical and perfectly crackable)

DVC1 start of solution (I seem to have a problem putting tiny text on this forum so see DJ's for the rest):

It has cages so it is fair to assume that it is a Killer of some form

No mention is made of using numbers other than 1-9 so it is fair to assume that this is a standard numbered Sudoku.

It is reasonable to assume that the cell values give a clue to the cage totals.

It is again reasonable to assume that the clue is for the cage containing the cell.

The most obvious assumption (especially to me) is some form of KiMo linkage.

Given the 8 at r3c1 we are limited to KiMo-10 or KiMo-9.

Consider the doublet at r34c4 with a 5 at r4c4 if it is a KiMo-10 then this implies r3c4 = 0, but we have already assumed 1-9 hence r3c4 = 9 and this is a KiMo-9 puzzle.
