Pyrrhon - 2010-11-10 1:51 AM

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 .

Pyrrhon

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.

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

Munira (and everyone else with small screens): I think I've found a fix and have tested it out on my local copy of the authors page. Deb will be adding the fix to the test pages sometime soon, which should work for almost everyone. Sorry about the inconvenience!

Players with small screens - Please scroll towards right if you can't see the IB / PB.
David - thanks for helping in fixing this issue. We'll apply this technique in the next test.

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.

The change in score display is interesting.

Although it gives you a (false) sense of being at the top (at least till the test is underway), you do get to know the number of people below you. As for the number above you, it keeps you guessing till the end.

I like this change, as long as the scores are not discussed on the forum.

Overall, it was another great experience for me. I have never done any sudoku puzzle that has Renban Groups in it. Unfortunately, I lost 42 points because the internet went down and i didn't finish typing the answer to Symmetric Unequal.

Congratulations to Rishi, Fred and Jakub H. for topping in Renban Grouped Sudokus.
Rishi continued from his great performance in Hotpot (where he stood second behind Thomas S.) and finally, we have an Indian at the top of the table.
There is very little to choose between Fred and Jakub with only few seconds differentiating them.

Nice to see Rohan completing all the grids well ahead in time.

deu, cpickerel and willwc played really well to complete all the grids.

Few more players had chance to complete all the grids, but minor mistakes crept in (especially Jason who lost the 2nd place because of a mistake in 6X6 Symmetric Unequal)

188 participants, and 167 non-zero scores - both better numbers than any LMI Monthly Sudoku test.
Thank you everyone for participating.

Please share your feedback about puzzles and / or rate them, if you have not done so yet.

Zafer, thanks a lot for the wonderful sudokus. I'm sure everyone enjoyed them.

Also thanks
to Ours Brun, who pre-tested the Sudoku, he completed all the grids in very impressive time.
to Rakesh Rai for reviewing the IB completely.
to David for designing the test logo.
to Rakesh, Rohan and Tejal for taking the test earlier in the weekdays, to find out potential issues because of our recent database upgrade. Fortunately, there were none.
