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. :)

What was logic in LOGO Sudoku?

What was logic in LOGO Sudoku?

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

Yes, it is a prerequisite. Thanks for adding.

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.
