Place the numbers 1 to 9 once in each row, column, long diagonal
(marked with a heavy dot) and every 3x3 grid.
' 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.

My understanding of this, as is yours, is that a "cage" forms an enclosure as in an animal cage, thus 2.
Umm? You might also have made a similar contention about the "4+" group of the same colour. That also has a similar bordering.
Is this an issue in how you colour? To a point I think Penny offers a legitimate question. Given that, might a possible extension of this to allow such a format? You can't call it quite in the same category from which this was developed but it could offer an "off-shoot".
Penny? Fair comment?
