There are several sites out there that might help you, e.g. http://act365.com/sudoku.

Can you try to do the elementary ones first. There are quite a few of simple ones to fill in.

In box 8 there is a single (5) which leads to naked pair ( 1, 9 ). After a few eliminations such as R4C6 you will find a naked pair in box 7. Then it is plain sailing. Good luck

[lizpun]

thanks for that but i dont know what a naked pair is and i dont understand the r4c9 or what ever you wrote. sorry

So, you go to work and someone gives you puzzles?! I'm impressed, but may I suggest a bit of pragmatism:

1. If it's part of your job to do this, then take all the time you want while at work and learn to do them - and get paid for it!

2. If it's not part of your job, then either:

(a) cheat and bung all the clues into a solver,
(b) tell whoever gave it to you to go and ........ while they ........ with a ........

Can I suggest you go to one (or better still both) of these sites:

http://www.angusj.com/sudoku/hints.php

and

http://www.simes.clara.co.uk/programs/sudoku.htm

They give some excelent descriptions of the various solving techniques, invaluable for a newbie.

However to get you started, you should be able to put 1 in r3c9 and 5 in r8c5. In both cases it is the only value that can go in the cell.

If you now look in box 8, cells r8c4 and r8c6 can only have the values 1 or 9 (ie the form a naked pair). This means that 1 and 9 cannot go in any other cell in box 8, ie r9c6 cannot be 9. Therefore c9r6 must be 6.

what is r3 and c9??

[SteveF]

I guess r3 means row 3 and c9 means column 9.

However I wrote r3c9, which means the cell located at row 3 column 9.

As I said last time, if you are interested in solving, I strongly recommend doing some reading up. If you want to impress some guy at work, get a solver program (available at both web sites I posted previously).

Thanks Steve. I have solved my puzzle

[Karyobin]

Wow. From beginner to accomplished in a thread. We can use this to beat the Creationists - Evolution can be observed!

[Jeff]

Liz, now that you have understood the basic, I suggest you go to here to practice on the easy ones. It's good fun.
