!! 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) !!
Isn't that totally tortuous...
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.
@Teejee : Bah, Teejee, tu devrais prendre des cours de mathématiques ; comme ça, tu pourrais compter le tentacule qui est caché derrière en raison de la grande profondeur de l'image ;p .
Et sinon, je me demandais si l'octopode lineulier était l'équivalent de l'heptagone régulier, non constructible à la règle et au compas...
