15 there she goes

If that bottom corner is logical then it must involve some logics way beyond me... like assuming.

On bottom right, the bottom 1 goes far bottom left and the top 1 goes far top right. work diagnally and do the same on final set.

Bottom corner I got through hypotheticals, so seems hard logical. For a hint that makes it single line solveable, the bottom right corner is white.

Thank you Dsrobey.

Good job Thank you.

Nice picture.

Solvable to one logical solution. Does take a tiny bit of 2D logic. Overall, a wonderful hanjie though 8D.
