Draw a non-intersecting path from one side to the other of a 6x6 grid. Row and column clues like Wordle.
I usually get these in 3 with a strategy of guess something that fits the clues.

See if your local library occasionally runs a booksale. I get most of my books that way. Their prices are competitive with thrift stores, usually about $1 paperback and $2 hardcover. But because it's run by friends of the library, tends to be higher quality and better organized. At those prices, I can afford to be disappointed, and sometimes get pleasantly surprised.
