!! This hanjie is a contactless hanjie (CLH). It is only logical with the constraint that no horizontal segment meet any vertical segment (except possibly with the corners) !!

Just a hanjie to wish Teejee a happy birthday ;)

Difficulty : *****

Tested, logical (as a CLH).
Smile-logic and some CLH-techniques can be usefull. You can play my series "Contactless hanjie" to learn some of them.
A micro-reasoning based on sums can be usefull at the end.
Good blackenage.
