!! Warning: This hanjie is a linea, it is only logical with the constraint that the picture consists of a single curved line, thus each black cell has exactly two of its four nearby cell blacks (except the two ends) !!

That one is not on my desk...

You can play the first season of "Linea" to perform your skills.

Difficulty : ***

Tested, logical (as a linea).
Edge-logic can be usefull.
Good blackenage.
