Flash Super Mario Bros is one of those classic Mario flash games that just nails the simple, jump-and-run fun. You pick Mario or Luigi—I always go with Luigi because, let’s be honest, he’s got that slightly better jump—and then you’re off stomping Goombas and dodging Koopas like it’s 1995.

The controls are tight, the levels are short but satisfying, and yeah, it’s exactly what you’d expect from a stripped-down Mario flash game. No frills, just pure platforming nostalgia. If you’ve got five minutes to kill, this one’s a solid choice.
