Killer-X-tra (Posted on 2008-05-27) Difficulty: 3 of 5

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.

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?
