Are there any good casual/low-stress mobile games that aren't filled with microtransactions? For example: easy puzzle games, match-3 games, low-difficulty adventure games, or clicker-style games.

So far, the only good examples I've found are Monument Valley, Suika Game, and (sort of) Vampire Survivors.

I'm personally looking for games that have more progression or variety, but any suggestions are welcome.
