Black star seems inevitable. Otherwise it would be the only row with no black star. Also, it would complete the pattern of black star moving from 1st to 3rd position.
It also is a perfect fit for a sudoku style with every symbol appearing not only once per line, but also per column. And completes “3 of every kind of symbol”.
