Post-excavation #1

All the Sudoku Excavation pages at the menu have been taken down. You can still get the puzzles here:
Large 9×9 puzzles
Small 6×6 puzzles

Solvers were asked to guess the authors of the puzzles, scoring points by doing so. Here’s a rule of thumb: if the sudoku is of a math-related variant, contains little givens and is frustratingly difficult then you can sanely bet that Sinchai wrote it. The guy loves solving and making math-variant sudokus. Or he just likes mathematics. Did you know that he scored 100% in our country’s Mathematics National Entrance Examination? Well, you do now.

You can see the rule in effect since Sinchai was responsible for the murderous Killer, Fortress and Sum 100. Others include Thermometers, XV and Consecutive. I wrote all the small puzzles (except the Consecutive), Kropki, Even Odd, Arrow and the final Mammoth fur puzzle.

Speaking of the last puzzle, Mark Goodliffe says that it’s always so much more fun when a puzzle (hunt) builds towards a finish.
I agree!

A very diligent Nick Brady: I did this in one session lasting about 7 hours and had much fun with it.
Now you know what to do on your next intercontinental plane trip.

Ivan Koswara: I just threw the Classic Sudoku to some online solver.
You cheater, you.

James McGowan: Can I assume Tamziania is somewhere near where you live?
Tamziania is a Google Map snapshot of the hospital car park where I am currently studying (and losing most of my sleep) at. As a shout-out, I also plan to use you dearest readers as characters in future events. Keep an eye out for yourself!

Zbigniew Laskowski: I thought I would become a killer myself when I received the killer clue from Fortress and realized that I had spent so much time solving that killer without the clue.
You can hunt down Sinchai for that, I’d never do such a thing to my readers. 🙂

Extra thanks to all solvers who fill in the comments box, my favourite part of an event is selecting some of them to post at the end (like the few above). So that’s my side of things. Sinchai might have a few words when his boss isn’t requiring his attention.

finalpuzzlesudex At the conclusion of our exhausting project, I asked solvers to guess who wrote the puzzles that form the fur of the Sudoku Mammoth. Since me and Sinchai aren’t that prolific (yet), most of the responses were probably guesses anyway. Certain points were allotted for each correct guesses and the maximum total is 50 points.
Note that all the point values in the table below are doubled (since I got lazy with decimals) but this doesn’t affect the standings.
Here are the results with the top 5 being omitted: sudexressneak Please don’t be discouraged by the standings, as they are most likely to be guesses and someone has to win. So who’s missing? 
Let’s introduce our top 5:
First to submit was Swaroop Guggilam, he was either the first or second to send in an entry throughout last three events. What an early bird! Coincidentally, second to submit was Swiss sudoku legend Fred Stalder, one of my favourite sudoku authors. This is his first entry at SOTR. He writes for many offline and online venues and all the puzzles are collected in his blog; and you can find that address in my blogroll. Two more newcomers made it to the top 5; one is Valerie Garcia; thanks to Fred who posted about it in the French forum, she and several other French names found out about our expedition. The next lucky newcomer is Stefano Forcolin who I’ve met and exchanged a few words with at the 2013 WSC. Lastly is Eva Myers, she made it to the final 8 of rock-paper-scissors way back in the first Nikoli Hurdles, good to see her back!
Now the final results…! sudexres Congratulations to Valerie Garcia from France scoring a whopping 94/100!
Interesting that Fred actually had more correct guesses at 9/10 but Valerie’s total is one point (initially 0.5 before the double) higher. More interesting is that one more competitor also scored 8/10, which is Zbigniew Laskowski who ended up at 6th place because his two incorrect guesses were worth higher points.

Again, all points were random and pre-determined which shows how it came down to luck for this little prize draw. For winning, Valerie will receive the Mammoth Book of New Sudoku by Gareth Moore. We have now come to the end of Sudoku Excavation. I will post solutions and comments about the whole event throughout the next few weeks. I would to thank co-author Sinchai and all 28 of you who’ve made this event so enjoyable.

Construction of my next event is already underway and it is scheduled for April. All I can say is it will include a variety of puzzles combined into one nice little theme. Pop back here for more details or subscribe to get notifications in case you forget!

Bye for now!

Final week for Sudoku Excavation

We are now approaching the final week of Sudoku Excavation. If you are still out there digging in Tamziania, you have a few days left to go. All submissions that I have received thus far are replied with a confirmation e-mail.

Apologies for late replies, I’m usually much more active online than this, so these confirmation emails may take up to 3-4 days.

If you’ve entered and have not heard from me, please check that your email address is spelt correctly in the submission form and try submitting again.
