Crossword puzzles use a grid of black and white squares that traditionally obeys the following rules.
1. Every word (a string of consecutive white squares in a row or column) has at least 3 letters (white squares). Each letter is part of a word going across and a word going down, and there are no 2-letter words.
2. The grid is symmetrical. It is the same upside-down.
3. The grid is connected. Between any two white squares, there is a path of white squares that only goes horizontally and vertically.

(I have a program that hunts for higher ones - but the
new solutions keep being mentioned here in posts ahead
of the program :-)
The program takes 3 inputs: min blocks by row 8, min blocks
per row and max blocks per row. But it takes a while to
complete. I am looking a little further just in case.
