Also, in Pentomino Samurai, will we get the grid in samurai fashion in the actual PB (instead of assembling them first like in the IB)?
Th IB says that "It means that to solve the middle puzzle it is necessary to find the correct positions of outer puzzles". Identifying which corner goes where is a part of the solving process. |

In IB, the rules of Price Tag has the following: "each placeholder becomes a digit". Does this mean every set of segments must become a digit and may not be left empty? For example, in "_1 + _9 = 10", there are two empty places.
There aren't empty placeholders.
_1+_9=10 is invalid.
And don't forget that numbers cannot start with zero, so 01+09=10 is invalid, as well.

Amit is right.
There will be five separated grids. You can recognise the middle one, because its corners are grey. Just like in the example.
You have to build up the correct Samurai grid.

You're right. I missed this points from the IB.
The grids cannot rotated or reflected. |

In Pentomino Samurai is multiple solutions possible while individually solving, or individual grids also will have unique solution. The four outer puzzles have unique solutions, when solved independently. |

Location: India | Points tableEach round, as mentioned in IB, is worth 120 points. Here is the break up.
Round 1 - Price Tag - 3 puzzles. 30 + 40 + 50
Round 2 - Pentomino Samurai - The 4 outside puzzles are 20 points each. The central puzzle is 40 points.
Round 3 - Great Wall - 8 puzzles, each Wall puzzle is 15 points.
Round 4 - Black & White Matrix - 12 puzzles, each individual puzzle is 10 points.
Also, a quick note about Instant Grading - Each puzzle has a "Submit" button, so you can check the small puzzle's correctness before finishing the complete round.

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.

For Great Wall, can segments be on the grid edges?
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. |

Location: Indonesia | | What was your most favorite round? | Round 4 - Black & White Matrix | | | How balanced do you think the puzzle types of this test were? | Perfectly balanced | | | What did you think about the puzzle quality of the test? | Fairly Nice | | | What was your opinion about the answer key extraction? | Answer keys could have been better | | | What was your opinion of the booklet formatting and printing? | I have a different complaint | |
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 |
