Yeah, I actually found the Raven's Matrices kind of fun. I found a book of them (Kindle, of course) for $10 I'm going to do for fun. https://www.amazon.com/dp/B09YKPFT6T/ref=cm_sw_r_cp_apan_A7NKC8D3G6XJAJHVY3AQ
I do those Penny Press Logic Puzzle books for fun, too.
They never seem to have them in the magazine racks anymore, only sudoku so I have to order them online.
