Rules:

Normal irregular 6x6 Sudoku rules apply, i.e. each row, column and region has to contain the digits from 1 to 6.

Rellik Cages: All cages are Rellik Cages. In a Rellik Cage digits do not repeat, and any combination of one or more digits within that cage CANNOT sum to the value in the top left.
