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

My thanks goes to brianjn for his hard work in producing the graphic.

You're welcome to do that, Josie, although Dej Mar's spreadsheet solution is probably more in the Sudoku spirit than my laborious program.

Also I'm sure Charlie and others could write much more efficient and concise programs than mine.

But if you'd like to cite it in the official solution, please feel free to do so.
