Place the numbers 1 to 9 once in each row, column,

**long diagonal**(marked with a heavy dot) and every 3x3 grid.

The '

**cage**' inclusions (individually coloured regions) indicate the sum or the product of the numbers in those cells.

Unlike Killer Sudoku, the same number may appear more than once in a cage. So, 36x in a cage which overlaps the 3x3 grids may contain two 6s and a 1.

*My inspiration for this puzzle came from a variety of puzzles posted by Pete and Will at http://sudexel.com/forum/index.php*
