### Where can I find more?

Just found a (to me) new variant in a nice Swedish book called "Paul Vaderlinds annorlunda Sudokubok". Haven't seen it before and enjoyed it a lot. Now I wonder what this would be called and if there are more of these somewhere on the net? The idea:

Code: Select all
`abc|abc|abcdef|def|defghi|ghi|ghi-----------abc|abc|abcdef|def|defghi|ghi|ghi-----------abc|abc|abcdef|def|defghi|ghi|ghi`

Basic rules apply, but the 9 cells labeled 'a' must also contain numbers 1-9 once, the cells labeled 'b' must hold numbers 1-9 once etc. Here's a 8x8 example (#73 from the book):

Code: Select all
`2.|..|..|.4..|1.|7.|2.75|..|.4|....|..|..|..--+--+--+--..|41|..|6...|..|..|....|.3|8.|...2|..|.5|.3`

You are talking about the Dijoint Groups variant.

here is a link to a thread where this has been discussed before (contains more links) http://forum.enjoysudoku.com/viewtopic.php?t=3480

Thanks tarek. I must agree with Andy (see link) that enough attention hasn't been paid to this variant, as it's really fun and challenging. My guess is that it's too difficult for the vast majorities, but for those who find basic newspaper sudokus too easy, I'd say this is an very interesting variant. Adding the "disjoint group"-constraint is so much more fun than just making the puzzle bigger or changing the shape of the boxes.
