Thanks for the link. Thus spurred on, I'll attempt a 144 x 144. Watch this space.

### 100x100 sudoku solved by anyone?

Hi Mike,
When you're back from holidays, can yo tell me the 100x100 is solvable?
At the moment I'm still busy to solve this one, using a 20 level deep
search, but that seems not to be enough?
I'm sure a 12 level deep search is not enough ...! This takes only 20 secs
CPU, but 20 levels takes magnitudes more..

To the rest of the community:
Did anyone else solve this one already??

BTW: Your 144x144 sudoku posted later just takes me 1.2 secs to solve,

### Here is another one - no 'normal sudoku?

this 100x100 java one
( http://puz.hp.infoseek.co.jp/nikki/number100.html ),
it does not what I expect it to do.
You can enter 21 on r1c1, while 21 is on r2c1 already
And on r2c8, you cannot enter 1 thru 9, so there is some rule behind it.
Is this not a sudoku with each number only once on every row or col??

1) So, what ARE the rules for such a sudoku?
2) Does this also explain why I cannot solve the 100x100 one by Mike Metcalf?

I wonder how long it'd take you guys to solve my two 8-clue 9x9 puzzles in here...

(The 2nd one is probably a blitz... But what about the 1st one... )
