It’s interesting how most people here are talking about casino-style games, but I think “games” can mean a lot more than that. Not everyone is looking for betting or high-risk gameplay.
Sometimes simple browser games are actually more enjoyable, especially when you just want to relax for a few minutes. I personally like quick games that don’t require downloads or sign-ups — things like classic Snake or small reaction-based challenges.
Recently I found a site with a collection of lightweight browser games that run instantly: SZ Games — it’s pretty simple but perfect for short breaks.
