Location: United Kingdom | I'm looking forward to this one and have managed to complete all the 6 x 6s in the instruction booklet apart from one - the Symmetric Unequal Sudoku. I expect I'm missing something really obvious but I can't work out which cells are 180 degrees symmetric to each other. 
Can anyone try and explain it to me please? Thanks. |

Location: Turkey | Hi,
In the symmetric unequal sudoku cells that are 180° symmetric to each other
cannot have same digits.
Keeping in mind that R corresponds to row and C corresponds to column; If
we talk about 6x6 R[n]C[k] can never have the same digit as R[7-n]C[7-k]
all n, k from 1 to 6 and if we consider 9x9 this time R[n]C[k] can never
have the same digit as R[10-n]C[10-k] for all n, k from 1 to 9 (of course
not both 5 same time).
Try to apply this rule once. You'll see it works. Hope it is more clear now.
Regards,
Zafer |

Location: Turkey | And who are interested about symmetric unequal sudoku may try to solve my 9x9 example on LM Germany site with the following address:
http://www.logic-masters.de/Raetselportal/Raetsel/zeigen.php?id=000...
It is not a hard one also. You may try it as an exercise.

Location: United Kingdom | Yes - I've got it now! Thanks for taking the time to reply - I've never come across this sudoku variant before. It's always great to come across a new puzzle type so I will go and try out the 9 x 9 now!

Location: Germany | Renban is a puzzle type invented (so far as I know) by Inaba Naoki. You can find his examples at http://inabapuzzle.com/honkaku/renban.html . (All digits occur in each row and column, all cages are renban groups.)
The oldest sudoku variant with renban groups is Hanidoku ( http://www.hanidoku.com/ ).
Other renban at http://www.sachsentext.de/en/node/1156 and other hanidoku at http://www.sachsentext.de/en/taxonomy/term/162 .

Thank you for sharing history of Renban. I'm sure this will be informative to many players.
Also, for those who don't know, Pyrrhon's website http://www.sachsentext.de contains list of many many Sudoku variants. You google for any Sudoku variant, and sachsentext.de is most likely to be in 1st page.
Thanks Uwe for maintaining such a wonderful website. |

I also want to thank Uwe (aka Pyrrhon) for sharing information about Renban . Some puzzlers may not be familiar with this subject. I also follow his great site http://www.sachsentext.de and learn about different variants Uwe deals not only with sudokus and the site has a lot of different puzzle types also. But I know that solving Uwe's designs is always enjoyable. He shared some of them in LM German puzzle portal also. Maybe Uwe will manage to conduct another monthly sudoku contest for LMI in the forthcoming months. I think it will be a great.
Regards,
Zafer

Aha. This explains many things.

Location: United States | 1. I naively thought from the Results tab that all the good sudoku players had been kidnapped and tied up in a closet somewhere as no one had passed my middling score.
2. Now I understand why I am the leader only in my own mind.
3. Was this explained somewhere ahead of time? I must have missed it.
4. Why is this the case and why dont you want us to see the others?
Thanks.
