Administrative question: I recruited non-IPC-participating initial test solvers for the puzzle(s) I authored; should I provide their names to ensure they are credited?

One Question:
Round 5: Tapa-Nurikabe
1. Can Clue in Nurikabe extend in Tapa Region and include a given Tapa clue (sole or multiple number clue) as part of Island?

- Extend in tapa region - Yes. The 3 in R5C6 extends in to the Tapa region in the example.
- include a given Tapa clue - ONLY if it is the sole clue for the Nurikabe island. Refer answer to 2.

2. Can a Sole Tapa Clue act as Both Tapa as well as Nurikabe Clue?
Yes. The rules specifically say - "the sole numbered cell for the island may be a Tapa clue"

I think there is a typo in IB, in Round 5 Puzzle 1-2, the Masyu section, "the path must not turn when it passes through a black pearl" should omit the 'not'?

Thanks, Rakesh for clarifying most of my doubts.
Hope my understanding is clear on this now. As per my understanding, a given Nurikabe clue cannot include Sole or Multiple Tapa clues in the Island. Please correct me if my understanding is wrong.

Yes. You are right. The path must turn on a black circle like usual masyu rules.

Clarifications from the Q&A session:

1) "Official" round timings: The official start timings for each round will be strictly followed for each round as in IB page 2.
2) Adobe Flash Player will be needed to participate in this contest.
3) Round 4 - Mark My Puzzles - The rules for the three puzzle types will be included on the page.
4) Round 4 - Numerical Jigsaw - Same font as in the IB shall be used for the vertical strips.
5) Round 5 - Ayeheya - The symmetry shall be with respect to the central point in the region.
6) Round 5 - Tapa+Nurikabe - Tapa clues can double up as nurikabe clues if that is the only clue in the island and if it is a single number.
7) Round 3 - Aquarium - Every region behaves as if we are pouring water from the top. So any two cells in a region (even if separated by other regions) either both have water or are both empty.
8) Round 5 - Tapa+Nurikabe - There cannot be two clues in a nurikabe island. There must be at least one "white" cell from nurikabe area to call it an island.
9) Round 1 - Rassi Silai and Tents - If the leftmost column is the 10th column, enter 0.
10) Round 1 - Battleships - Fleet shall be given and given ship segment cells will contain same shape as in given fleet.

14) Round 3 - Products (Off by one) - Specific range of numbers shall be given in the PB.
15) Round 4 - Meteor Showers - Validation shall be added to the length of the answer
16) Round 3 - Top Heavy - The rules apply only for vertical neighbours (number at the top shall be bigger). There are no constraints for horizontal neighbours.
17) Round 4 - Banners - All words shall be listed vertically.
18) Round 5 - Masyu rule - The text "the path must not turn when it passes through a black pearl" should omit the 'not'

A big thanks to the organizers for putting together the five rounds for this IPC. Each and every round was very enjoyable and had loads of memorable puzzles.
The points and time allocation for each round was spot on.

Special thanks to Rakesh, Priyam and Deb for putting in so many hours of effort and for the perfect execution even with limited support. (I hope I am not missing anyone out.)
Also thanks to all the authors for the fantastic puzzles. I will share my thoughts on the puzzles after solving the ones that I missed out during the contest.
