Password protected pdfs uploaded.
Note that the marathon puzzles are in a separate pdf.
~~Both the pds share the same password (which obviously will be displayed after you start the test)~~

We would like to apologize for mistakes in some of the puzzles.
1) The LITS image in the pdf is incorrect. We have uploaded an updated pdf. So all participants who are yet to participate please download the updated version.
2) The Nurikabe 10X10 puzzle is incorrect.
3) The Numberlinks puzzle has multiple solutions.
4) The Heyawake marathon puzzle is incorrect.

Extremely sorry for participants have already taken the test. I am sure you must have had a great time solving the rest of the puzzles. Hope it will serve as great practice for the WPC.

Frankly, I am a bit disappointed by the mistakes, as I wasted some time trying to fix the nurikabe and the LITS is a lot of points, but then again it's not like I was going to win anything anyway. I'll just solve the corrected versions and when I see my low score I'll have an excuse :P Still, I hope the people responsible take something out of this and be more careful next time :)

I haven't even started the marathon puzzles. Judging by Tom's post yesterday, I'm in for a treat :)

I will take the blame here for this disaster - just not good enough I'm afraid.

We are currently discussing what to do. I have proposed the following:

-the nurikabe and numberlink are broken beyond repair and ought to be removed from the test (bringing the total score for the first section down to 920). Participants who have already finished the test should be compensated for the wasted time.

-the LITS is fixable. What will happen here is either the same as for the numberlink and the nurikabe - or else a new PB will be uploaded, and all earlier participants will be awarded the full points.

Once again, my sincerest apologies

I had the bad luck to solve the wrong PDF.

This is what I found:
#1 Numberlink - multiple solutions
When I realized it, I just found a solution that is using all cells and got points
#5 Akari - 4 solutions
For luck, all solutions have the same answer, so no problems with it
#12 Nurikabe - wrong image
I spent a lot of time on it. After time limit I solved the bigger Nurikabe for about 1/3 of the time I spent on this.
Actually, it's very easily fixable: just change '4' to '3' at R5C10
#16 LITS
I also spent some time until found it's wrong (one small line, but a big difference)

The heyawake marathon was wrong? I didn't notice. It did take me quite a while to solve it - about 75 minutes - but I didn't see any mistakes. I'm sure I can easily be missing something and the correct version that Tom posted looks quite a bit different. Can someone tell me what the mistake is? Or is it that the one in the booklet is still a valid heyawake, just not the one that was intended? That would be a weird happenstance :)

I didn't notice either

- until it was too late.

There was a thing quite early on in the solve where you have a choice between either entirely surrounding an empty square with shaded squares, or else leaving 3 rooms empty in a row. The latter option was apparently quite subtle as I must have passed over it at least four or five times. Either that, or I'm an idiot.

The new version is basically a fiddle to change as little of the solving experience (after wrongly assuming the 3 empty rooms in a row) as possible - I'd estimate about 80% of the puzzle solves the same.

I obviously had the benefit of the "improved" test, but that won't keep me from my typical counting error (on the highest possible valued puzzle to boot). Got through all the solvable puzzles though. I think the marathon Kakuro was guilty of being too cute (not a good thing in a competition), but otherwise a lot of very fun puzzles to solve. Thanks for the puzzles Tom.

I made it too although my PC froze as soon as I copy/pasted the pw. Had to reset and reboot and lost 5-6 minutes. Therefore I guess this time motris will beat me

Nice set of puzzles, although I did not always find a straight relationship between the points awarded and the difficulty level. Thanks Tom, better luck for the future

detuned Posts: 152 Country : United Kingdom	detuned posted @ 2010-10-10 5:37 AM I didn't notice either - until it was too late. There was a thing quite early on in the solve where you have a choice between either entirely surrounding an empty square with shaded squares, or else leaving 3 rooms empty in a row. The latter option was apparently quite subtle as I must have passed over it at least four or five times. Either that, or I'm an idiot. The new version is basically a fiddle to change as little of the solving experience (after wrongly assuming the 3 empty rooms in a row) as possible - I'd estimate about 80% of the puzzle solves the same.

motris Posts: 199 Country : United States	motris posted @ 2010-10-10 10:24 AM I obviously had the benefit of the "improved" test, but that won't keep me from my typical counting error (on the highest possible valued puzzle to boot). Got through all the solvable puzzles though. I think the marathon Kakuro was guilty of being too cute (not a good thing in a competition), but otherwise a lot of very fun puzzles to solve. Thanks for the puzzles Tom. Edited by motris 2010-10-10 10:25 AM

forcolin Posts: 172 Country : ITALY	forcolin posted @ 2010-10-10 2:54 PM I made it too although my PC froze as soon as I copy/pasted the pw. Had to reset and reboot and lost 5-6 minutes. Therefore I guess this time motris will beat me Nice set of puzzles, although I did not always find a straight relationship between the points awarded and the difficulty level. Thanks Tom, better luck for the future stefano ps: how do I rate the puzzles? Edited by forcolin 2010-10-10 2:55 PM
