Puzzle 26 – “How Do I Work This?”
I still like playing with grids with all-over symmetry: rotational, left-right, and top-bottom. And as I’ve done a couple times with all-over grids on this site already, this one’s built on 4 intersecting 15-letter entries. Your title is a clue to 31-Across. Other favorite clues include 23-Down and 29-Down. And because they lend some fun facts to otherwise familiar things, 11-Down and 35-Down. As always, happy solving, comments welcomed. Hope you enjoy, friends.
