Vampire Survivors had it, kinda. It was just miniboss drops, random, like a typical hack and slash, but opening a chest looked like a silly slot machine animation jacking straight into my gambler brain (I don't actually gamble - I have many other bad habits but I realized I might be wired dangerously back when I played cards for small sums of money with my classmates as a teenager. So I actively swore off gambling and never fell for it, apart from "fake" gambling in video games, where I'm always reminded of why I shouldn't touch it in real life)
