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 took 3/6 minutes for the 15/30 points. Definitely undervalued.

This was really fun. Thanks for the puzzles! The domino castle, in particular, was really cool.

And looking at the results, I typoed the arrows. Darn!

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.
