I mean, you can't go wrong with consequence-free gambling? Maybe? Balatro is easy to pick up, satisfying to play and really good at wasting two hours of your life. It has some degree of strategy, although you roll with the RNG punches most of the time. It does hit that dopamine by being designed that way. I enjoyed these vibes a fair bit, but I'll mostly play this on long train journeys, I think - when my goal is to experience as little of time as possible.
