Although I prefer to indulge in other puzzly things like scrabble and chess, I find the Su Doku quite easy, because to me it's simple reductive logic. The thing that throws some people is that because the rules say you can have only 1-9 once in each row etc, then people jump to the conclusion that the diagonals are the same which isn't the case. I don't play it but if I did I'm confident I'd be very good. I've played other logic puzzles like Frustration (this is a 9 colour 5-string code version of mastermind) and solved it. I don't mean to be boasting here btw!

You have to develop some slightly more complex strategies for the harder ones, once you've eliminated the easy stuff, like

pencil in the two possible values in a cell, then do all the "two value" cells like this, then loop round doing a "what if this one is a 3?" procedure.

For any row, column, or block of 9, check if there's only 1 cell where a particular value will go...

There must be a website with all this on!

6. ive got a link for a daily sudoku puzzle but i want to get a huge book of them now

damn further maths and that quiz style lesson
7. Yeh your right they're quite addictive. Most newpapers have 2 or 3 each day. BTW have you tried looking on http://sudoku.com? It gives solutions and a months free trial for a computerised sudoku game. Yes it really is addictive (going off to play)
8. I've done a few of the harder ones, as well as the one's with 4 3x3 grids on. When you get used to the method, it gets easier and easier to do them...
9. i can't do it yet - but then again i've not had the time to sit down and practise!!!
10. I can do all of the ones in the Times easily enough
11. Ooh I do love a bit of Su Doku. I normally do the Difficult ones in the Times. I've got one of the books! I did do a Fiendish in the paper the other day though; I was so proud that I cut it out and kept it!
12. The first one I did was a fiendish. I can just do em theres not one in the times that I've not managed to do yet. its very odd cos I'm usually crap at logic puzzles.

Yea the first one I did was a Fiendish.. but I didn't finish it, just messed it superbly. That's why I was so proud of having completed one!
14. I love the Sudoku puzzles, though find the really hard ones a bit tough to do. I get the different books, though don't know which one's the best. Though there is one with about 90 or 100 puzzles for £1.90
15. To fascinate you all with an update, I started doing the ones in the Sun (pity my parents lol) yesterday, and it takes me roughly 20mins to do the harder ones. It's something to do at least!
16. I love the samurai sudokus in the times on saturday, does anyone else?
17. Oh yeah, I love this game- 2 days ago my maths teacher got us hooked on it. I managed to do the easy and medium level, but the hard ones are just out of my league! Our whole class was playing it, and I got to admit, my teacher was sooooo good at it!
18. ive bort a book for this puxle and im working throw it at the moment i cant put it down
19. hahah i love sudoku. i think i once did a hard level, but i havent done any for ages.

My first sudoku was in The Times or Independent, it was like this:

[3][2][1]
[2][1][3]
[1][3][ ]

They gave a clue - it's not 3 and it's not 2.
(they were talking about the proliferation of sudoku in newspapers, and this was The Sun's version!!!! !!)
