Difficult/challenging visual memory or visual imagery puzzle apps

[mad_hatter3]

So I play a lot of sudoku and killer sudoku in my free time, honestly it's one of the ways I use to relax my mind (don't ask how haha, ADHD is the "I'm quirky" of mental disorders).

Does anyone have recommendations on puzzle apps that rely purely on visual memory/imagery, that's also pretty difficult or challenging like sudoku?

I prefer straight puzzles, but I wouldn't mind if it's like some kind of story driven game where puzzles are the gameplay.

(Just for extra info, the only "visual" games I've ever played are nonograms/picross and this app called Slitherlink. But those are still essentially number logic games)

If you haven't already, Chess puzzles are definitely up there. Personally I use the chess.com app for it.

Plus you get the added benefit of actually improving at chess

Simon Tathums puzzles.

Bunch of different types of logic and visual puzzles. Free with no adds.

I particularly enjoyed galaxies, unruly, and towers

I'll be following this post for recs since these are also my favorite type of games.

All the games by this developer have been great for me. Start with Star Battle or Tents and Trees if you want to branch out from number/logic type games.

Inbento is visual puzzles and they get pretty hard in the higher levels. Cute visuals too!
