Location: France | Very pleasant contest ! I'm very proud of finishing the 1st round within 60 minutes, and very sad of having sent a wrong submission (a stupid wrong touch) on the 1st puzzle.
A point is not clear : because of my stupid mistake, I know I will have a penality of 1.5 minutes, but I never saw that I will lost 10% of the puzzle points (so my points are 27+40+50 instead of 30+40+50). Why ?
No mention of this point in the IB, neither in this thread !? |

Hi, there is no points penalty for wrong submissions.
however, the test has a very difficult point system, so it can have some wrong elements. I'm sure Deb will fix it soon. No need to worry. Finally, you will get 120 points.

No. Rules from the IB:
"the whole grid consists exactly one line which starts and ends on the edge of the grid, and never goes again on the edge or on dotted line. " |

Location: Hong Kong | In round 4, I can't seem to resolve grids 6, 7, 10, and 11 at the same time.
Given my answer to grids 4, 8, and 12, the I-pentomino must lie at the very bottom of grid 7. However, this means (via shading a few cells in grid 6) that in grid 10, R3C10 is shaded, forcing R1C2~6 and R3~4C1 to be shaded in grid 11. It is impossible to have paths go through all of these cells, so I must conclude that the puzzle is broken. |

In round 4, I can't seem to resolve grids [restricted]
Please note that in puzzle 7 (Pentomino blokus), it is not necessary to use all the pentominos. (Each pentomino should be used either once or never) |

I can say only two things.
The first is that some people have already solved this puzzle. So I'm pretty sure it has solution.
The second is that, maybe it can help if you read again the rules of 6,7,10,11, and look at the sample grids. |

The only two complaints about the PB are also the complaints that makes my perception that this test has the worst PB. No rules in PB and no numbering puzzles. No rules means one must always have the IB along, and no numbering puzzles means it gets really confusing to figure out which answer key we have just retrieved. (On a tangential note, answer keys could have been better, but that's not the main problem.)
The puzzles themselves are pretty nice. I'm not sure whether it's just my problem or indeed Round 4 is too devilish, but I'm pretty sure things are imbalanced when Rounds 1 and 3 are topped at 15 minutes something while Rounds 2 and 4 are topped at 30 minutes something. (But hey, it's still first two days.)
Well, that's all, I suppose. Also, as a closing remark, there is some kind of wonderful accomplishment when you beat Palmer (at Round 3) :3 |

Hi Ivan!
Thank you for your feedback.
I don't think that the lack of instruction means a problem. But the fact that I didn't clarify that the PB wouldn't contain instruction was a real problem, indeed.
Sorry for that.
In R1,R2 the puzzles have a number. You can find it in the tables on the top of the page.
In R3 there is only 1 puzzle, and in R4 it would be hard to add a puzzle number.
I think in R2, R3 and R4 the letters on the arrows can replace the numbering of puzzles.
About the answer keys: R2, R3 and R4 have a similar layout, so we wanted to creat a same answer key. This was the main point. It was important to us to avoid the confusions in such a complicated test structure.
And this was the best one that we could find out. Please let me know if you know any better. Don't forget that the instant grading needs a fix length or a fix sum.
Well, the balance of rounds was less important for us in this case. We didn't want to make a well-balanced competition just provide some practise puzzles. And we had two choices, we just publish these puzzles on the WPC blog or we announce a competition. We chose the 2nd alternative, and I think it was a good decision instead of the mistakes of this test.
I can't say that we know the 4th round is much harder than the others. It can be true.

Location: United States | @chaotic: Indeed, good work. I had a lot of moments where I took a few minutes to solve a grid despite it being dirt simple, so I wasn't too surprised to get beaten on that one.
I'll also be surprised if any of my current 1s hold at the end of the week. I didn't completely blunder any of the rounds, but I didn't exactly hit any home runs either... |

Location: India | Hi
I have a query on Round 4. It states that two puzzles will be identical in the shared edge.
Is this implies that Puzzle 1 and 2 share an edge and Puzzle 1 and 5 share an edge. Can someone clarify this rule for me. |

Hi

Is this implies that Puzzle 1 and 2 share an edge and Puzzle 1 and 5 share an edge. Can someone clarify this rule for me. I am not sure what exactly your question is.
So puzzle 1 and puzzle 2 share an edge. Since you already have the pdf, I can say that Column 10 of puzzle 1 and column 1 of puzzle 2 should be identical. Like in the image below.
Does it help? Feel free to post if something is still not clear.

Location: India | Thanks Admin. So similarly, Row 10 of Puzzle 1 and Row 1 of Puzzle 5 will be identical and so on.
Also I have a question in Paint it Black. I will send a PM to you as I dont feel I can post here. |

Location: United States | Enjoyed the puzzles this time around, but definitely felt that round 4 was out of step with the first three. Extremely cool idea and execution, but I ended up spending longer on round 4 than I did on the first three rounds combined. It was also a little difficult to figure out how to progress on some of the puzzles, since you had to apply adjoining logic to find a solution that met all the requirements, but I eventually got there. Used a lot more trial and error than I would like, but glad to have had the chance to tackle that beast. |

I got owned by Pata pretty hard. I did not realize that the key squares are counted as white squares. The difficulty of the test seems to vary widely for me though. Round 1 and 3 took me ~1/2 hour, while Round 2 and 4 took me over an hour, and that's not including the botch I have with Pata. |

Location: The Netherlands | The rank bonus seems to cause a big discrepancy in bonus values for rounds with fewer finishers (especially round 4 currently). Shouldn't the bonus just top off from 60 (1st 60, 2nd 59 etc.) unless there are more than 60 finishers? |

Location: France | The rounds were definitely of very different difficulty levels -- all were a lot of fun, I think most people will agree that #2 and especially #4 were harder than #1 and #3. This is par for the course in WPC and all the puzzles were really well designed (though I really played #4 poorly and then got close to not having enough time to finish it before a meeting scheduled for 75 minutes after my start time...). But I do tend to agree with Bram and others that this seems to be to make the bonuses for rounds 2 and 4 quite sensitive to small variations in solving time or even rank. Perhaps this will go away once more people complete all rounds. Or else, it might be something to watch for in future such mini-marathons -- allotting different amount of times to the different rounds might have been better. -- Denis |
