Yin-Yang or Black And White is one of my favourite puzzles. The puzzles were very well made and it was worth spending 2hrs on these puzzles, even at midnight.

That was harddd

Yes it was quite difficult, especially for players who tried it for the 1st time.
Since I started playing puzzles, I had barely solved 5 (easy) Yin-Yang puzzles before the test, so I wasn't too confident, but I am pretty satisfied with my result. Indeed it was difficult but I managed to concentrate enough to solve several hard and nice puzzles. After having been crushed by Melon's LMI test, it re-instilled in me a little self-esteem. There were some really interesting variations; in particular, I found the Tapa Yin-Yang very pleasant.
Hope to see another Yin-Yang variations contest some day.
You did really well considering you hadn't spent much time on it.
Shame on me!
