Thanks, I got it.

These are all worthy of being in a contest set themselves, my favorite so far is definitely the No Rectangles.

A quick note about penalties: as the IB says, we doubt there will be any manual answer entry correction on this test. In particular, the penalty will stand if the solver is at all at fault for the wrong answer, even if it's a simple typo or a right answer submitted for the wrong puzzle. Please keep this in mind as you take the test and check for stupid things like that.

In addition to the Preview series from the two test authors above, there's also a Liar Fillomino by Para that can be used for practice -

Because I love advertising my blog. :P

Nonconsecutive Fillomino, in case this opening trick is used in the test.

That is truly Fillomino Fever all around :-)

Is the snake allowed to have length one? I'm just wondering because one of the puzzles I created (which was mostly a joke) would have multiple solutions if this were allowed. I hope that the snakes will have length more than one on the test :)

Don't think we ever really decided if there is such a length restriction. That will be a nonissue on the test.

The snake has "a head and a tail". Technically it would be of length at least 2. But I'm sure the authors won't make such joke puzzles ( http://kitkatksun48.wordpress.com/2012/10/22/fillomino-snake/ ) :P

Thanks for the excellent puzzles. This is up there with my favorite tests of the year. The Nonconsecutive, No Rectangles, Skyscraper were all superb. I unfortunately broke both Liars towards the end and couldn't get any submission in. I dunno about others, but at least with Liars I find paint far less error prone, and I solved both Liars fairly easily on paint later. Its difficult to mark the digits as true or false and then write over them on paper, compared to simple colour-coding in paint.

I'd love it if this Fillomino contest became traditional like the TVC. There seems to be a lot more ways to experiment with this puzzle.

The only thing I personally don't understand is that the penalty stands for entering the key in the wrong puzzle,etc. Not to sound bitter but to get a penalty for a puzzle I didn't even actually submit the answer to during the test is a bit harsh. Instant Grading is a nice way to show typos and such, but any reason why this time the penalty stays for these errors unrelated to puzzle solving?

And I second that.

How do we enter multi-digit answers? Eg: I am getting 10 as one of the 'digits' in a circle, but cant submit the solution since the total 'digits' is greater than 8. Could be a wrong solve from me, maybe.

@lenson, enter the unit digit (right most digit) in such cases
so 0 for 10, 1 for 11, 2 for 12, 3 for 13, so on ....

Enter only the last digit, as per the answer key instructions. A 10 should be entered as 0.
EDIT: Beaten :O

Prasanna: The basic rationale is that the warning about no manual entry correction was stated up front. Those who account for that and take the extra time to check the little things like that lose time in comparison to people who make small goofs and get forgiven for them later.

Thanks for a really fun test! After enjoying FF1 so much last year, I made sure to give this one a whirl, and it certainly didn't disappoint.

As a merely sub-superhuman solver, I was happy to put away all the 6-point-and under puzzles (except Classic 4), and it was a thrilling finish to successfully crack the 'splurge' hard puzzle I picked to focus my last 15 minutes on, Walls (Bottom). Just couldn't resist, that empty grid of tetrominoes screamed "I'll be your favorite!", and they were right.

Like FF1, I look forward to working through the remaining gems in a more relaxed state over the next few days. Congrats Grant and Palmer, and thanks again!

Well, my opinion is that that gets penalized enough if you just don't award the points. Now say, someone puts X puzzle's key in Y's entry. If the person doesn't get points for X, then thats enough, and if it does later get changed, that means the solver took the time to change it anyway.

Anyway, I know it was mentioned up front, I'm not asking for a change, I just wanted to know why thats the case.

For Fillomino Skyscrapers

I made for OAPC 9, you can find here: http://oapc.wpc2009.org/archive.php?id=49

Also you can see: http://www.sachsentext.de/en/taxonomy/term/160

Thanks for the test. Really enjoyed walls, nonconsecutive, sum, and the last classic.

Pretty happy with how I did, although I'm not sure how I managed to break 5 puzzles (which were luckily all quite easy to fix.) -10.2 points is a lot...

Amazing puzzles in this. I'm EXTREMELY satisfied with my performance, considering my sub-400 rating. My favorites would be Classic 4, Hard Nonconsecutive(but I broke it), the Sum, and the Hard Walls (YAY http://kitkatksun48.wordpress.com/2012/10/23/fillomino-wall/).

Amazing test. Hard walls and hard liar were my favorites, though just about everything was great. Thanks for all the puzzles.

Amazing puzzles. I should have interpreted the penalty warning as "your final score is multiplied by (100 - 2 * penalties)%" instead of "the puzzle's score is multiplied by (100 - 2 * penalties)%" before I decided to try submitting (intentionally) an incorrect answer (and costing me 1.8 points) :P Enjoyed bottom Nonconsecutive the most, with bottom Skyscrapers placing a close second.

Also there is something fishy. kumara answered a 6-point puzzle within 7 seconds. Did kumara hack the puzzle booklet or something? The puzzle booklet's password has entropy of 64 bits anyway, so... (Sorry, couldn't resist putting the xkcd reference :P )

We already have figured this out. It is simple case of having multiple userids, so kumara will be disqualified (not for the first time, unfortunately)

I was planning to give this test a skip after taking part in sudoku cup earlier...but i am happy that i managed to scrape in just enough time to take this test...loved the snake fillomino very much....puzzles are meant to be solved for fun and i cant think of a better example than snake fillomino as the paragon of fun for this test...and skyscrapers fillomino was good too...clean bowled though seeing the second skyscraper fillomino..i wonder how people even start doing such fillominoes without a number and still manage to complete it in a decent time...would love a walkthrough this time for the second skyscraper fillomino...overall a CLASSY monthly test!!!!!Great work melon and grant!!!
