Neither one nor the other.
So what would fill the gap instead?
Maybe doodling. But it doesn't use the same part of the brain, I assume.
Anyhow, I can't doodle on 200WaD, nor can I set a grid for words or numbers. I can't even do ASCII art here!
Since the only thing I can do here is writing, I figured I could at least offer a few definitions:
1. King, but not queen - 2. Sounds good - 3. Hell of a day - 4. Very short - 5. Beijing express - 6. Silver - 7. Over there - 8. Winter is coming - 9. Summer berries - 10. Magic mushroom - 11. Flat city.
A. Goonies - B. Southern star - C. Nest of spies - D. His better half - E. Spicing things up - F. White powder - G. Light element - H. Washed or natural - I. Very moving - J. Wet pet - K. Full circle.
Now, I let you plot them on a grid and create for yourself a beautiful crossword. Don't bother using the order I applied to the lists above. This is really an invitation to creativity. Actually, you can even change the definitions. There you go, you have your very own crossword!
I can also provide you with the raw material for a sudoku: one, two, three, four, five, six, seven, eight, nine. As I said, the grid is on you.
