This puzzle has lots of solutions.

Not logical after a point, too many possible answers to solve.

Two hours of trial and error ... why do I have to be such a completionist?

I tried many times to solve this puzzle and I just managed it. The puzzle is symmetrical horizontally, vertically and diagonally.

SPOILER:

there are four diagonal arrows, the arrowhead is formed by the 4s
in the space between the arrows are four boxes with a cross in them.

Thanks. It was easier once I got the pattern.

I know this is old, but this is absolutely one of the worst puzzles on this site. the second half is PURE guess work. I found at least 6 unique incorrect answers before I got the correct one.

In order to solve, you must know that there are diagonal lines connecting the "arrows" in the four corners to the center. Hopefully that helps.

A good design, but a bad hanjie.

THank you very much for all the clues! Would be great to have puzzles that only require logic and no guess work.

Thank you Gudi for the spoiler it helped when I got to last 4 dots.
