Highlight to reveal my workup (and don't quote this post unless you want to spoil a possible answer):

I always find the process more interesting than the product.

Your horizontal order was different than mine. I used:
Color - Nationality - Drink - Cigar - Pet

But I also used vertical, (same order as my horizontal):

(Box containing color name)
Nationality
Drink
Cigar
Pet
