HINT: The 10 in r15 starts in c2. From there it should be logical.

Thanks for the hint Ekkonic, could not have done the hanjie without it. Please check your puzzles before posting.

Solvable to two logical solutions with 2D logic. VERY tricky, very enjoyable, but NOT a three-star difficulty. This should absolutely be five-star difficulty.

Thank you Ekkonic for a clue :)

Thankyou EKKONIC for your neccessary hint.
Not easy, but worth it!

Thanks for the hint.
