Country : Germany | CJK posted @ 2021-11-10 2:08 AM In the first puzzle of the instruction booklet (Log-In), I think there is "ESC" missing at the given words.
And for Mahjong Maze: Why is 11213222 not a solution of the example as well? (We then would have a set of 6-6-6 Dots and a pair of 5-5 Bamboo)

Country : Romania | At Part 01 - 01 Log in is the "ESC" word missing in the list? |

6.4 Tera XX, It looks like we can replace the last row with 4760. There are multiple solutions.
6.12 Gogiken Naname 3D, "Gogiken" looks like a typo. The upper corner in the puzzle doesn't match the answer. |

Country : China | Because each mahjong tile can appear ?4 times in the path. The IB should be fixed. |

Country : Italy | 6.4 Tera XX. I believe this type first appeared at WPC 2019 with the name "Terra X" (two Rs) and a sum value of 10. The variation with sum 20 was misspelled in Puzzle GP 2020 Round 1 as "Tera XX" with just one R. It would be nice to correct this. |

montelucci
Country : Italy | 3.10-12 Mahjong Maze. Is this another valid solution to the example? Take 2,3,1,2,2,2,1,1 tiles per row. (3-4-5 and 6-7-8 dots; 1-2-3 and 6-7-8 bamboos; 5-5 characters) |

Country : New Zealand | kiwijam posted @ 2021-11-12 10:09 AM What a great IB! I'm looking forward to next week, after missing this from last year.
In addition to the previous posts, I have found in the v2 pdf:
6.7 Nanro Cave: "No identical numbers from different regions may not be orthogonally adjacent to each other." - Remove the No?
10.2 Digital Kakuro: The instructions mention Placeholders. Does this mean that hint numbers could be "?" (=1 to 9) or "??" (=10 to 45)?

New Version of IB
The next version of the Instruction Booklet, with points, is now published on the landing page. Soon the competition round links will also be published there. For quick reference, the new IB can be found at https://www.worldpuzzle.org/files/106/ws+pc%20puzzle%20IB%20v3.pdf
Changes to the previous IB:
- Points added
- Several duration of rounds are changed
- R1: One word (ESC ) missing from word list in "Log In"
- R3: Reworded instructions and fixed example in "Mahjong Maze", with new rule added: 5 identical tiles or more may not be visited by the path. Fixed typo in "Go"
- R4: Added 'lines may not crossed bolded regions' in "Rassi Silai"
- R6: Renamed "Terra XX" and "Gokigen Naname 3D". Fixed typo in "Nanro Cave"
- R7: Changed answer keys of "Akari"
Any further issues will be handled in forum unless critical.

Country : Japan | R2 Sashigane: In the example puzzle, the grid lines are presented as solid lines. Will this also be the case for competition puzzles? It's far better to present grid lines as dotted lines in region division puzzles.
R3 Muddy Creek, Go (etc): Could you make swapping Xs and Os allowed (as in Puzzle GPs)?
R5 Multi-Skyscrapers: How exactly is the partial scoring system going to work?
R6 Gokigen 3D: In the example puzzle, topmost three cells are divided incorectly. Division seen in its solution is correct.
(R8 Railroad Tracks: Answer key with Ls and Xs feels a bit cumbersome, why isn't it consistent with other loop puzzles?)
R8 Masyu: If a grey circle is used by both loops, should it be a Masyu circle for both loops? Or is it allowed for one loop to be neither?
R8 Railroad Tracks: What happens if two loops intersect in a cell adjacent to a clue not belonging to a circle? Does the number represent the total in such case?
R10 Curve Data: The text says that for the answer key enter the lengths of the segments, but in the example answer key ("23, 32"), numbers of cells belonging to segments are counted. Which of these is correct? |

Country : India | R2: It is dotted in the PB.
R3: Yes we will do this.
R5: 25 points per correctly solved puzzle. There will be separate keys for each puzzle.
(I'll allow Tawan to answer the rest)

Hello Ectoplasma,
First three questions as answered above.
R6: Gokigen Naname 3D. Yes, the puzzle image is wrong, the top cube should be like the solution's diagram
R8 Answer keys: We understand it is going to be a pain, but with two different loops crossing each other frequently, we felt I,L,X (as sometimes used in PGP ) was easier to understand.
Masyu: Grey circles need to only be a valid Masyu clue (black or white ) for at least any 1 loop only, it can be valid or invalid in the other.
Railroad Tracks: I'm not sure if I understand the question. All Railroad Tracks clues will be in a circle.
R10: Your understanding is correct. Enter the lengths of line segments for each marked row or column, along the marked direction. Not the number of cells. The example answer for the IB should be 12,21

- R3 P12 Mahjong Maze is 105 points (instead of 110 points), making the total of 1500 points.

Oops. I meant “Tapa-Like Loop” when I said Railroad Tracks.
R8 Tapa-Like Loop: The loops will not be able to intersect at a cell orthogonally adjacent to a neutral clue, since it means that a loop will cross-over to the cell with a neutral clue (which is prohibited in the rules ). It can, however, intersect at a diagonally-adjacent cell to a neutral clue, in which case the total of both loops is counted. Therefore, it is possible for a neutral clue to have numbers add up to more than 8. |

Country : ITALY | GaS posted @ 2021-11-14 3:39 PM Hi all, I'm reading the Puzzle IB and I noticed that 9 out of 10 rounds have a ratio total_points/minutes very close to 10; the only exception is the "Made in China" round with a ratio of 1500/80 = 16,6
Can you confirm the total point of this round will be 1500? it seems very strange to me, but I'm certainly not an expert, such an "anomalous" deviation from the rest of the rounds. In such a way round 3 (Made in China) seems to have, on average, a greater weight than the other rounds on the final result
(Triple Jump ha s a ratio 950/80=11,8, all others have ratio of exactly 10 or very close to 10)
Thnaks very much,
Gabriele |

Country : France | auroux posted @ 2021-11-16 10:33 PM Gabriele: my guess is that, because the puzzles in "Made in China" are quite far away from classics, and have relatively few distinct puzzle types for such a long round, the authors have provided way more puzzles than can be completed (by mere mortals at least) in the 90 minutes, so that most of us will be able to choose what types of puzzles we wish to work on and still aim for roughly the same amount of points per minute as in other rounds.
In other terms: if you expect to barely finish the other rounds in the allotted time, expect to be able to get a score of roughly 900 on this round, and it's ok if you are completely incompetent a., for instance, Mahjongg Mazes because there are enough puzzles of other types. |

Country : India | rajeshk posted @ 2021-11-19 1:55 PM In Gokigen Naname 3D, instructions say that draw the diagonal lines. However, in the solution, both the top 2s are connecting along the line instead of diagonal?

Country : India | Yes, this mistake has been pointed out before in this thread, the cells are drawn wrong in that part of the puzzle. The rules are correct. |

Country : United States | In the instruction book for Cave, did the sample solution flip the shaded squares? The shaded squares are not supposed to be part of the cave, correct? |

Country : India | The puzzle solves the same either way, its just different notations. |

Country : United States | "Shade some cells to leave behind a single, connected group (the cave), with no enclosed, shaded cells. In other words, all shaded cells must be connected by other shaded cells to an edge of the grid."
This plus the flip of what's shaded in the example led me to think that what I wasn't shading were the walls of the cave and because they were unshaded, the walls were allowed to be enclosed. I should've tried to solve the example - I would've noticed there wasn't a unique solution with that interpretation.
Going back to the competition puzzle, this is making much more sense now, thanks. :)
