Congrats to Thomas for winning Crazy Arrows with a big lead. Congrats to Nikola and Kota for 2nd and 3rd respectively.

I got the idea of Crazy Arrows last year, and I'm glad I could finally conduct this test. The test was tough, and some of the sudokus were very challenging for players.

0-9 was my favourite variation of this set, and also was the first variant that I had thought of.

Count was the easiest sudoku of the set and 90% of the players solved it.

Difference was difficult to start, but once you get few numbers correctly, the grid solves quickly.

Incomplete was another easy sudoku and this was Deb's idea that I worked on.

Missing was the toughest of the set. Guesswork was needed in multiple places and only 5 players were able to solve it. This is now the least solved individual sudoku on LMI so far. Maybe you can try to crack it!

Parted was not easy. After getting a few initial numbers, there is a little guesswork required.

Product was one of my favourite sudokus. The idea was taken from USA where it appeared in WSC 2010.

Skyscraper was relatively easy compared to the other sudokus.

Sum 1 was tough. As Jason mentioned in his post on LMI, it had a very 'Killer feeling'.

Sum 2 was my favourite. And it also is the favourite of the players. Most people commented on this grid and it has the maximum rating too, so, I consider this the cream of the set.

Symmetric was the one sudoku that couldn't make this test a neat one. It was worth 75 points and I apologize for the mistake on my part. It was much tougher and deserved a lot more points. It was also very difficult and a lot of players might've been affected by this and I regret the mistake.

Wrong was one of my top 3 sudokus of the set. Many players might have had a hiccough while solving when seeing a '9' on an arrow and a '1' in a circle. But I guess most of the players realised that it does work that way :-)

I thank all the participants for removing time and participating in Crazy Arrows and I hope you'll enjoyed at least a few of the sudokus. Hope to see you again in 'Crazier Arrows'!

Another new dimension to LMI! A fast-paced test where every second counts. Puzzles were excellent. Full credit to Bastien for this fantastic set.
You make one error, and you lose chunks of relative time. Its quite disappointing that I wasn't able to finish all the 15 puzzles, especially when there are players who do it in half your time.
Congrats to Palmer and Thomas (I guess you'll are continuing the battle here too) and the Japanese for their excellent results.

Sudokucup 6 Part 2 was definitely much easier than Part 1. 27 Players finished all sudokus within the 2 hours compared to just 7 in Part 1.

Now that both parts of SC6 are over, I wonder who is the winner of 'Sudokucup 6'?

This was my first 'complete' USPC. Since it is midnight in India during USPC, I dozed off last two years.

Congrats to Palmer Mebane for ending Thomas Snyder's five-year reign at the USPC! Both of them have been performing consistently well in championships throughout the year, and I'm sure they would be among the top guns at the WPC in Hungary.

Before
Skyscraper Sudoku variants. This promises to be an exciting contest. The variation look good and Nikola has never disappointed me :-)
I'm been performing below par in the last couple of tests, maybe I can redeem with this one.



After
What a city! Nikola has proved he's the best architect among puzzlers by building this beautiful city. I'm sure most citizens who entered the city did not want to leave!
