Nice to see Rishi back. This test is based on variants of Killer Sudoku.

I'm not a big fan of Killer Sudoku, but this test will surely prove to give a good insight into Killer-solving techniques.

A nice, enjoyable test. Some really nice Killer sudokus. I had trouble solving the Toroidal and the Little Killer, but otherwise the solves were good.
My favourite were Greater Than Killer and Twin Killer.

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'!

Beautiful test. I think every sudoku had its own charm in solving and thats the mark of a good author.
I personally liked Group Sum and Quadruple the best of the set. I'm sure now everyone considers Serkan as a great sudoku author as well!

Looks to be an interesting set. Puzzles combined with sudokus would be advantageous to players who are comfortable with puzzles. Lets see if the results prove it.

A very nice set of sudokus (or puzzles!). I loved the Tapa 9x9 and the Easy As ABC 9x9.
Congrats to Nikola for the big victory! It is very rare to see Thomas not in the top 3. Congrats to Michael and Ulrich for a close fought 2nd and 3rd.

Here's my first test. I'm going to give my best shot at ISC and I hope to retain my title :-)

After
This is satisfying! I did not solve the test under best 'physical conditions', but an 8th place overall and Indian topper with a considerable margin is something that comforts me. Nice to see Gaurav, Sumit and others back in the ring.

Sudokus were excellent. A Trio sudoku with 6 givens caught my eye, something which I failed creating sometime back. It seemed many struggled with the Product Frame which I was lucky to get through but the only barrier I faced was Outside.

Congrats to all those who qualified and hope to have an interesting finals like last year.

A very interesting set of sudokus. I liked Sundoku the best among the dozen and it will be interesting to see how it is put to good use, I'm sure the 'Francophone Authors' will live up to my expectations :-)

I've never performed well when the range of the points distribution is relatively large. Having 10 sudokus in the 0-100 point range and the other two in the 140-160 category is bound to trouble me. Some jinx I guess.

But, I'm looking forward to this test, especially since its a light weekend for me and I hope I can crack the dozen within 2hrs.

Good luck to all participants!

After
What a beautiful set of sudokus! The test was well-timed, but a little difficult for ameteur solvers. Also, no one was able to solve all sudokus correctly, which was surprised me.

Alpha Frame, Classic and Consecutive were nice and easy.
Greater than Killer was wonderfully constructed. I made a dangerous error early on while solving, 1>2>3... Was lucky to catch this goof within a minute.
Sudokukurve is one variant that I loathe. I solved it only because it was the end, and the only other variant remaining was the Killer in which I wasn't getting good progress.
Arrow and Sundoku were again nicely made, both solvable logically.
Extra Region was fantastic to solve. The use of the four-number groups (of the region and corresponding row/column) was all that was needed to crack this puzzle.
Jigsaw is again not one of favourites, especially when there are letters, but I managed to solve it without a scratch.
Mixed Sudoku was lovely. I rate it the best of this set. I just loved the way the solution went from bottom to top.
Killer 0-8 was the only puzzle I didn't solve. Didn't get any headway and it seems to be a tough one as mentioned by others in the forum.
Double Sum. This was a smile-maker and a heart-breaker. I started the test with this sudoku and solved it in about 15 minutes. I was glad with the speedy start only to be disappointed later by an error in the answer. Damn! I missed a chance to be 4th!

Overall, an amazing weekend for puzzles... great job by the authors and looking forward to the next set of sudokus as always!

It was a fun test. Applying two constraints to a sudoku required a lot of concentration. In the midst of the test, I kept getting confused between the variants due to repetition. I read 'nonconsecutive' and I applied antiknight! Luckily I caught myself every time I blundered and passed it with a laugh. Its been a while since I stood in the top 10 of an LMI test, so its been a good weekend for me. Congrats to WaterlooMathie for pipping the ever-topping Snyder. Maybe Snyder will be back next month with a vengeance!

Top quality puzzles. They were complete fun to solve and the concept usage was applied very effectively. Peephole Sudoku and Rossini Sudoku were my favourite from the set. In Peephole, for a few seconds I thought it had multiple solutions, but there was a nice little corner that made it unique. That was class! The 'anti-Rossini' solved very beautifully and logically.
I'm surprised to see so few people solve Numerologidoku. I thought after getting the sums, it solved very nicely.



Good start to the new year. Hoping to see more participants and more enjoyment in the tests to come!
