Enjoyed the puzzles and the theme which was quite new to me.

Did a bad little blunder in the Outside sums sudoku that ended up ruining the whole bunch of 4 :P

Admins - I'm not sure if I entered the right answer correctly in the claim points box. If at all it matters, I'll gladly give it again.

hey thanks
hope so the contest puzzle is easy one.

Another excellent contest. Thank you, Vladimir. In spite of the mistakes, I made, I enjoy the puzzles very much. I envy those who have not yet solved these puzzles. Good luck for everybody.

Hi everybody,
at first I want to express my thank to the organisers and authors. This is one of the test types that was missing until now. I really enjoyed the puzzles.
Only think I do not consider suitable is the answer format for puzzles with blackened cells. It is impossible to check all the "-" signs. Probably my screen is not big enough, but I really think that it will be better if some friendly signs will be used. For example, when you write WWWWW or BBBBB it is easier as -----------
Thanks

Matus

Matus, very impressive performance from you.
On using the "-" symbols, the font used in the submission system makes it more difficult as well. So at the very least we should be using a different font. The Sudoku one already uses a fixed-width font. We'll change the font in puzzle submission system as well.


Unrelated note : There was a minor glitch in the score page where "total points" for 2 players was computed wrongly. It has been fixed since. Thanks prasanna16391 for reporting.

In order to avoid double standards all the claims for submission of the wrong row/column will be rejected. Please be careful entering your answers.

nice set of puzzles,
enjoyed a lot,
messed up in easy as abc, skyscraper.
performance was not so as i expected but any ways thanks to author for such an awesome contest.

Thanks for the wonderful test !
The concept was just fine and puzzles were really good !

(every puzzle tests should have many sudokus and other latin square puzzles, héhé ! and I should always check my codes when I decide to stop playing and the timing is not finished)

I am pretty new at using this site. I mostly download the puzzles and work them on my own, usually long after the contests are over. Today, I had my coffee, sat down at the computer, logged in...and I cannot see a password or timer anywhere. The blanks for entering solutions are there - but no password. Has this happened to anyone else?

Well I see that you haven't said that you clicked on "Start Forsmarts...". Do that if you haven't. Once you do that, timer and password will appear. If you did that as well, then there's some glitch probably that the admins will check out when they're online.

Hi Jeff, Once you're logged, you just have to click on "start forsmarts 9th annual competition" and you'll see the password and timer.
I don't see you in the list of participant, so I think you just didn't start.

Fred

That was fun - thanks.

Really loved the idea and the puzzles!

I was 90% sure I would have to skip this test but I found a few hours this evening and I am glad I did. These were very elegant combinations of classic types, with lots of good interactions between the grids. Thanks very much for these puzzles Vlad!

With no more participants at this point, Forsmarts 3² Anniversary Squared Contest is now over. Preliminary results available at http://logicmastersindia.com/forsmarts2011/score.asp Vladimir will check the last few entries before the results are frozen.

Congratulations to motris, for winning this contest with a huge margin. uvo is next with significant margin from misko. All of misko's submissions came after 120 minutes, and he lost 100 points.

A total of 205 players, out of which 155 players solved at least one puzzle and 148 players solved at least one set completely. Interestingly, tarotaro was the only player to have solved all 4 Dotted Snakes.

We haven't used Extra Time regularly in the past. But I felt many players lost lot of points because of using Extra Time. For example, xevs lost 53.2 - 18 - 8 = 27.2 points for fixing a typo during Extra time. (He made a typo at 018:50, he fixed it at 124:26) He would have got 27.2 points if he hadn't fixed the typo.

May be .2 per second was really high for this since the maximum points achieved was 835 points.

Penalty systems like this one often require a solver to calculate on the fly if they should submit or not and certainly some players will submit when it is not to their advantage.

I finished the last two battleship parts 4 minutes in extra time, around when it would have cost me about 42 points to submit. It took me 2 points of time to figure out 15+15+10 was < 42 and also now < 44 points of penalty so I never submitted. But I could have made this mistake and lost points.

I personally like extra time that operates a little more like T3ist scoring, so there is rapidly declining value for submitting in this time, but it is always worth something to submit and the competitor doesn't have to solve a separate puzzle of calculating his marginal score improvement. Perhaps 80% value for 1 minute over, 60% value for 2 minutes over, ..., 0% value for 5 minutes over.

Many thanks to all the participants! Congratulations to Thomas, it was an impressive victory.
Sorry if anyone felt being treated unfair when the claims for the points were rejected: rows and columns for the answer keys were selected on purpose. So to keep the judging consistent - all the claims on submitting wrong row/column were rejected, no matter if it felt like a trick to enter a line that could be filled in the very beginning of solving process or otherwise.
I also want to extend gratitude to Deb who created a wonderful handy engine for conducting online-contests and was very helping during the preparation to the contest and the contest itself.
All the best, come back next year for a jubilee contest! :)

In the top 20 of a puzzle test (until the last minute, I was convinced that Para will kick me out of the top 20)??? before the last 2 world champions???
I can't prevent to think that it's an interplanetary conspiracy

Fred

Some complacency resulting from my performance
I really could not believe, that I remain in the top 10. When I saw my nickname somewhere at 7th position and Thomas, Palmer, Taro, Ko or Bram still haven´t participate it become quite frustrating. I solve at Saturday morning and start with 3rd position, so I will be very sad if all these superb solvers overtake me in the last few hours. But they did not and now I wonder if somebody who is 211th in the puzzle rating could finish in the top 10.
Otherwise big congratulation belongs to the best performers and all the organisers.

Matus

Great puzzles, I loved them. Especially the skyscrapers and japanese sums.
Unfortunately I have no idea how can I solve the dotted snake. But this is a puzzle invented by me :) Thank you for the propagation. :)
This puzzle had the smallest number of submission, this calm me down a little :-)

Congratulations to motris, uvo and misko.

I've told you earlier, you should participate more often in puzzle tests

Certainly the rank of 211^th is not a true reflection of your solving abilities. Of the 12 tests considered for ratings, you have participated only once. That said, we definitely saw many top players not doing well in this test, it can't just be a coincidence.

I also want to mention that Vladimir has originally planned this contest for 150 minutes. Although I didn't oppose to running the contest for that long, I suggested to reduce the length if possible, considering that it was 3^rd consecutive weekend of puzzles at LMI (that too immediately after WS/PC). Obviously, he had calculated the the timing exactly, and my suggestion was without solving the set. May be running the test for 150 minutes would have brought the best out of everyone.

To explain my own performance, first if this test had been rated I probably would have unchecked the box. The Putnam (http://www.maa.org/awards/putnam.html) was not the only thing I had to worry about this weekend, and a lot of the types weren't ones I was comfortable with (sudoku? easy as? japanese sums?). Second, if you check my submission times, it was going pretty well, and then I stubbornly refused to skip the dotted snake until I had sunk 50 minutes into it. 420 points in the first hour, 28 in the second.

And since "last 2 world champions" was noted by someone, it seems tarotaro had a similar problem. To his credit, he did finish the dotted snake after his 50 minutes (only one as pointed out above).

Thank you for a very interesting and challenging set of puzzles. I performed dismally, which wasn't a surprise given how much I'd struggled with the puzzles in the instruction booklet! I'm glad it didn't count for ratings. Even now I have only managed to finish two more sets, so I don't think 150 minutes would have helped me much.
