  Killer Combinations
Each clue in each cage will give rise to a certain set of combinations of numbers for each cell. It is a converntion of Killer Sudoku that no cage will duplicate a number (even if it dog-legs through several 3 by 3 boxes).

Some cages will not be very helpful but certain combinations, such as these listed here mean that the total number of possible numbers is equal to the cage size. In the first, for example, a clue of 3 in a cage of size 2 can only have 1 and 2 in it. These means you can remove 3 to 9 from those cells.

I have written an example of the use of 'hard' Killer combinations on this page.
