Three turned to stone

jgiantsbanner2

I apologize for being one day late. I had my days mixed up this weekend. To compensate, I will extend the deadline for Cerberus by one more day. Entries will be accepted until August 4th.

Over the last 8 days, I received 30 entries to Medusa’s Snake Pit. The answer keys were a tad messy but that didn’t stop 27 solvers from getting to the correct solution.
Here is the list of correct entries in order that I received them:

  1. Edison He (who was also first in Hydra)
  2. Ken Levine
  3. Dylan Gibbs
  4. Adam Vangness
  5. Robert Vollmert
  6. Ben Wootten
  7. Nick Brady
  8. Alex Pei
  9. Logan Dymond
  10. Jack Bross
  11. Scott Handelman
  12. Stefan Tomlins
  13. Prasanna Seshadri
  14. Michael Deluca*
  15. Yuhei Kusui
  16. Willy Petrenko
  17. Eric Odenheimer*
  18. Antonis Lalatsas
  19. James McGowan
  20. Jakub Hrazdira
  21. Ivan Koswara
  22. Zbigniew Laskowski
  23. Nikola Zivanovic
  24. Branko Ceranic
  25. Andrey Bogdanov
  26. Zoltan Horvath*
  27. Matt Lahut
  28. Andrew Brecher
  29. John Reid
  30. Thomas Powell

Oh no! Three entries were incorrect.*
I cannot accept their entries since Medusa had already turned Michael, Eric and Zoltan to stone. Sorry! But do try again with Cerberus.

As for the 27 correct solvers, they will participate in a rock paper scissors tournament right after Cerberus leaves. Speaking of the devil, here he comes! Check out his puzzle at the menu above. The three-headed beast will linger around for the next 8 days.

Thank you for being with me throughout this year’s July Giants.
Enjoy the last puzzle!

Kota retains BRANDS Sudoku title

The 2014 BRANDS Thailand Sudoku Open concluded today. The usual 2-day format was increased by one day since in Thailand; it’s a 4-day weekend. The tournament started on Friday and the venue shifted from Siam Paragon to Central Ladprao, both are department stores in Bangkok.

From what I see, the conditions were awful. The instruction booklet was very sloppy and an unhealthy fraction of the puzzles were clearly computer-generated. Really the only thing this event is still attracting both local stars and international participants is the money. The winner gets to pocket a nice $5000 US.

This year saw an all-time low of international names. Just Jan and Kota returned. Yuhei was busy and the entire Indian team had to cancel their visit because the dates clashed with their hastily-organized Times Championship. Last year’s finalists Farhan Hassin (Malaysia) and Tung Yi Wu (Taiwan) were also absent. My friend, Gabriel Gan (Singapore) usually turns up as with a handful of Chinese players but none came this year. The only country to consistently field in a team every year is the Philippines. But ever since variants start to make more appearance than classic sudokus, none of them managed to leave any impressive results for the last 6 years.

Two funny things: 1. The logo has been re-used for the last 4 years (note “2011”) and 2. Poramet didn’t even sign up.

Let alone solvers from overseas, Thailand fielded an even less impressive roster. Only two members of our national team turned up. Sinchai Rungsangrattanakul, who recently entered to world’s top 10, was our nation’s favourite. College had me and Poramet occupied for the weekend so only rising star Supachai Thongsawang join Sinchai as our front-runners.

Given the many absences, the final five was somewhat predictable. Sinchai collected the most points in the preliminaries so he earned the stage’s centre. Sandwiching him was Jan and Takuya Sugimoto, a newcomer to the event. Kota was placed 4th and I understood there was a tight race for the last spot which was narrowly won by Supachai.

The finals must have been a nail-biter as Kota became the first person in this event’s 8-year history to successfully defend his title. Jan finished second again and the revelation of the tournament goes to 18-year old Supachai who squeezed out a third place win.

Here is the puzzle that was used in the finals. Print out a large copy and try solving it standing up on a wonky board to get the real simulation of the finals.

You can compare your times with the finalists, here:
#1: Kota Morinishi (JPN) 8.43
#2: Jan Mrozowski (POL) 11.39
#3: Supachai Thongsawang (THA) 12.13
#4: Takuya Sugimoto (JPN) 14.03
#5: Sinchai Rungsangrattanakul (THA) 20.00 – DNF

I would love to welcome international solvers to this event, but I still think there are too many things this tournament can improve on. Our national association is not very energetic at addressing them so do come along but don’t expect the best hospitality cause you’ll probably be disappointed. Lastly, can I ask again who wrote the few handmade puzzles for this event? A lot of people want to know who our national association has ties with and why they are making it so secretive.

*Alas! Hydra claimed two victims!
Jack and Nick (both submitted 34 and were one cell off from the right answer) will have to be excluded from the tournament bracket. Sorry! Try again!

As for the remaining 21, I won’t reveal the results just yet. You’ll have to be patient. Why not increase your odds of winning by slaying a few more giants?

Argus Panoptes is now the current giant on this blog, he is a lot tamer than Hydra. Click on his name at the menu above to see what you’re up against this week. You have until the 18th July to solve the puzzle before Medusa arrives.

Have fun!

Four giants approaching!

Solutions to Anchors Aweigh – 4/4

Puzzle 6 – Double Battleships
puz6twotwo

I first saw this type at the 2013 WPC in Thomas Snyder’s round. The puzzle above was easily the hardest out of all the puzzles in Anchors Aweigh, to which solver James McGowan rightly agrees: trying to keep track of what’s happening in each cell. I did it in MSPaint, so had 6 colours in action.

The reason this last part of the solutions took so long was that I intended to write up a full solving guideline. As much as I wanted to do so, my study timetable disagreed, so we will have to just make do for now. My starting point was at the 4th column with 5 and 3 adding up to 8 (leaving two cells blank). I remembered vaguely how the puzzle solves from left to right but since a couple of months has elapsed, I have very little memory about it.

Puzzle 7 – Classic Battleships (Hard)

puz7clash

Despite the label, I don’t think this puzzle was that difficult at all. You have to try out horizontal/vertical orientations of the long ships to get through the first part of the puzzle.
Then you should have a few ships left at the end to satisfy the two 3s in the 9th and 10th row.

And that’s all the puzzles covered in Anchors Aweigh. Thomas, Antonis and Walker had all received their prizes.
Want to be the next winner?
Well, I’ve already cooked up more puzzles for future events and it looks promising from here.
Come back in a few days for…
