I think in Japanese Sums Hitori Style "the clue in 4th column has to be 2 - 13 -13 instead of 2-13-11 as given in IB " ?

Yes, you are right. This is typo. Correct clue should be 2-13-13

I suppose number 0 is allowed in XI areas where it is possible because there is one 0 in the example of 2D Magic. But what about Japanese Sums Hitori Style? Can we get combination 7-0-4 or 11-0 outside the grid? I never saw a word about zero sums in basic rules of this puzzle type.

Puzzles like 2D Magic and Slitherlink where 0 is part of the usual classic version of the puzzle can have 0 in the XI areas. Puzzles like Japanese Sums where there normally isn't a 0 outside the grid, cannot have 0 in XI areas.

on my page due to screen problem
penalty is showing as : NaN. so i didnt knew how much it was
but i submitted bottom pyramid puzzle assuming that this points would be greater than penalty. but now i see that my negative points are more. i thought if puzzle points submitted is less than negative points it would not be considered ?

Apart from this awesome puzzles. But i feel many are on hard side. Also i feel the penalty for extended time is very high.
Thanks to authors for wonderful test. The kropkuro bottom and pyramid bottom are my favorites.
have to solve all remaining ones.

I finished Sudoku (Bottom) with -48 on penalty, but that's not including entering the answer keys... D: (So I decided to ditch it.)

My favorites among those solved are Sudoku (Top) and Fillomino (Top). Fillomino (Bottom), Domino Castle, and Snake (Bottom) follow. A nice test, using those 11-areas effectively. Perhaps a few minor complaints are the rapid penalty (but then you already have 120 minutes), quite some puzzles being mostly trial and error, and the dominoes not forming an easier-to-inspect shape:

You have
00 11 22
01 12
02

I prefer
00
01 11
02 12 22

This was so bad...... I managed to botch the domino castle multiple times, and somehow not being able to figure out the fillominos. Worst still, by the time I fixed the castle wall, the penalty is already -59, so I said screw it. On the other hand I am proud to say I got the both kropkuro and the Japanese sums. The penalty is a bit steep, seeing how the highest point question is 140 and the maximum penalty is 180.

By the way, out of curiosity. If I submitted a question worth 60 points when the penalty is -65, will that lower my score?

Thanks for the test. Despite finding the IB and its examples somewhat terrifying, I enjoyed this test more than I enjoyed the previous anniversary competitions.

Fillomino Top was my last solve. That was the hardest puzzle on the test for me. :(

I found the fillomino a bit dreadful too. Were they that easy?? I spent 20+ minutes on both of them for only 45 points.

I intuitively solved the top Fillomino pretty quickly, and communicated the same to Vladimir. I suppose the intuitive ones are easier when you're solving one at a time. Also, approaching such puzzles with an open mind is probably better than approaching them expecting them to be really easy.

For the smaller one, I just figured out it'll be two 8 shapes, two 3 shapes, so the middle shape has to be 8, 2, 1. This covers all the cells, knowing that the 1 and 2 shape will be used to separate the 8s. Then it's all about whether both 3s are involved in the separation or just the bottom left one.
