One question about 1. MAGIC PUZZLES:
Can figures cover given numbers?
For example, is it allowed to place figure H on the top middle box?

It's possible. Figures can cover given digits.

Wow. That was tough, but lots of fun. Could have gotten one more puzzle easily if I hadn't gotten interrupted twice, but I guess that's the peril of doing puzzles at work... oh well.

Enjoyed the puzzles, but that was brutal. I think that was my worst performance in some time.

I think comments posted after start time of the test needs to be hidden until someone finishes the test.

These were cruel.
Don't get me wrong, the puzzles were fantastic but not sure if its competition-suitable.
My favourites are Snakes and Names.
Well-constructed!

Great Sudokus. But too tough for me personally. Will definitely solve it offline. :)

In LOGO all numbers into strips must be different and have a common divisor.

I used also the fact that this common divisor was one of these numbers

I thought the Magic Puzzles was a bit confusing: with the arrow next to the C and G pieces I thought they had to go on the left side.... which turned out not to be the case.

Otherwise, nice (and hard!) puzzles. Thanks Riad!

I think it probably would have helped to have a title that might have hinted to the rule. I think it was a bit too complicated. It took me 2 hours to figure it out. It was a really nice puzzle to solve though. Just the getting the rules was hard work.
