Play for your best time, here’s mine on my first try on easy.
This can be the official scoreboard, if anybody else wants to share in my addiction.
That’s strange, this one actually tells you if you made the right moves or not. Well it’s a good trainer I suppose. washingtonpost.com and a lot of other newspapers have a daily sudoku now, for more of a challenge.
I actually find it easier to keep track of the numbers on a printed paper, versus an online game. (playing with the game some more I see what you mean, it only accepts the correct number for the answer… someone could take advantage of that and win in under a minute.)
This one also has a “hinting” mechanism, but it lets you enter the wrong number.
Sudoku did the rounds in the UK about 12 months ago - even found it’s way onto a very funny sktch show called ‘Spoons’…
I’ve never played it, I think I’ll stick to GTA…
Su Doku: been there, done that, moved on 
After the standard ones, I moved onto Samurais, and having moved on from them I’m now on Killers, which I expect to move-on-from fairly soon to who-knows-what.
Btw, how do you lot pronounce “Su Doku” ? Me and my brothers say “soo do-koo”
How do you quote the score? I couldn’t get the image to download.
