Have just seen it, Heather! And the recommended solving time of 42 minutes. Will be having a go at it later. Good prize: Glastonbury tickets.:)

Have just completed this on my third attempt. I enjoyed it, and found it more challenging than the usual su doku. There is to be another Samurai in Monday's Times.

Samurai Su-Doku

Tried the Samurai today, and as an experienced Su Doke player I am confused. I thought that and Su Doku only ever had one solution. I've sorted out he top left Su-Doku, but the numbers on the bottom line of the bottom right hand quadrant don't align with the numbers in the middle Su Doku or the top right Su-Doku with regard to the positioning of the eight's!

I had that exact same problem with the eights! had to abandon it in the end, even though i am certain my solution to top left puzzle is correct!

In reply to Confused and Abi, if I read your posts correctly, you attempted to solve the five grids individually rather than as part of the larger puzzle. It cannot be solved this way.

I solved the middle grid first, and found it easier as i had more numbers in the corner sections.

No, it's not one of mine. I haven't seen it, so can't really comment. I take it there are 5 grids, overlapping by one box in each corner of the central grid? Puzzle magazines in Japan feature such overlapping puzzles quite regularly, in a variety of configurations. Ideally, none of the grids should be solveable in isolation - they should need help from their overlappers. The number of clues-per-grid should be fewer than would normally be the case.

Have completed this puzzle, i will post the answer after 10pm sunday *grinz* cant be having with other peeps stealing my tickets, but my advice is solve the middle grid first, as it has the most numbers helping it as the other 4 grids help solve a square in each, then work through the rest, i solved grids in C, B, D, A order but could just be how my wacky mind works:D
btw, my time was 43 mins... damn that toilet break:D

My wife and I have both completed it now. She did it by hand and I modified my solving program. None of the 5 grids are uniquely solvable by themselves. By comparing pencil marks in the overlaps the unique solution does come out.

took me 25 minutes to suss out that the overlapping cells are key - after that it's just like solving difficult level Sudokus.

oh, btw the wife's now left me

Thanks for all of the help and advice. I got the idea (and solution now).

Glastonbury here we come!

I solved it this morning.

It's quite a tricky one. Once I had solved
the middle one, all 4 ones round the outside
take quite a while for me to solve.
You can use numbers from the outer 4 to
help solve the middle one too which helps.

42 mins the japanese reckon ?
They must be real experts, it took me more
than 4 hours of concentrated time to solve it

I've put a scan of it on my website if you'd like to see it

Did anyone actually crack it in under 42 minutes? It must have taken me double that - it is going to make me fail my latin test now!:!:

If someone actually did do it in under 42, I'd like to know how!
