The normal rules of Killer Sudoku apply: Place each of the numbers 1 to 9 into each of the rows, columns and bold-lined 3-by-3 boxes. You must also place the numbers in each dashed-line cage so that they add up to the given total.

In addition, the grid is divided into coloured cells. Cells of the same colour must also contain all the digits from 1-9.
