You know what I would like to see? Variations! There are diagonal Sudokus, Hyper Sudokus (additional segments that also must have 1-9), MultiSudokus (one of more overlapping grids), consecutive neighbours Sudoku (more below), irregular group (jigsaw, nonomino, "squiffy") Sudoku, Sumdoku (Killer Sudoku), even/odd Sudoku, Magic Squares...and I'd also like the capability to create Wordokus and 5x5 puzzles!

Don't recognize any of these?

Hyper Sudokus - most recent I've seen is sent from a contact at Conceptis forums, where there are four additional 3x3 boxes in the grid; any kind of segment can make up the 1-9 rules though.

Diagonal Sudoku - diagonals have 1-9 as well, Pennypress and Dell have picked up on these in their Sudoku publications

MultiSudokus - no explanation required, go to

http://www.binaryworlds.com/sudoku/hard.php (BTW, URL recognition in using keywords with your links is horrible on these boards)

Consecutive Neighbours Sudoku - any pair of consecutive numbers has an indicator line between them. No line means no consecutive numbers in the two cells.

Irregular Group Sudoku - Michael Mepham has daily puzzles on his site now.

http://www.sudoku.org.uk/jigsaw.asp www.boldts.net has a Sudoku section with 20,000 of these, too, called Nonomino Sudoku.

Sumdoku - boxes inside the grid indicates sums of numbers in the cells; Cross Sums (Kakuro) mixed with Sudoku, grids often start blank. The Times in London does them now.

http://www.timesonline.co.uk/section/0,,18209,00.htmlEven/Odd Sudoku - odd boxes are normal, even boxes are shaded. Variations on this too.

Magic Squares - There are shaded boxes in each square, and the number of shaded boxes indicates number of cells. 7 shaded boxes, 1-7 goes in them, 89 in the other two. PrintSudoku does these.

www.printsudoku.comWordokus - Self-explanatory. Letters are used, and any row, column, or diagonal can represent a word. Codeoku is a variant where letters reading along left to right, top to bottom spell out something.

5x5 puzzles - basically 25x25 grids. 1-25 everywhere. May not fit on some screens.

Aside from variations, better support for libraries is a good idea...input our puzzles and print the library. I mean, we can already print 100 puzzles if we wanted at random, it'd be nice to print our own puzzles however.

Also, support for newer and better solving techniques is required. A lot of puzzles on

www.vanhegan.net ARE sovlable puzzles requiring new techniques such as the XY Wing, XYZ Wing, Nishio, Forcing Chains, and other methods. Go to

http://www.madoverlord.com/projects/sudoku.t to download SusokuSasser, a tool that can analyze puzzles that this site's Sudoku program considers unsolvable (and also can fetch such puzzles from some sites, such as menneske.no). It's technically tipware (but also free) application...meaning the application on THIS site does not stack up even with individual puzzles. The only features I like from this application right now are libraries (though they are still limited in their use) and the various sized variations, but otherwise it's nothing special and not worth the $20 (even more CAD) without improvements such as the above.

Those are some of my views. Comments, anyone?
