Play Mario Street Fight Online
Pick Mario or the gang and throw down in this janky Flash brawler—Peach’s umbrella slap never gets old, and Luigi’s flailing jump kick somehow works. Takes a minute to nail the weird special moves, but then you’re launching goombas into walls.

Mario Street Fight is one of those old-school Flash brawlers where you pick Mario, Luigi, Peach, or Toad and just start swinging. At first, I thought it’d be another basic button-masher, but each character actually has their own weird little special moves—Luigi’s got this awkward jump kick that somehow works, and Peach’s umbrella slap is weirdly satisfying. The controls take a second to get used to (good luck pulling off a special move on your first try), but once it clicks, you’ll be bouncing enemies off walls.
You can tweak the difficulty, adjust lives, and even mess with power levels if you want an easier (or way harder) time. It’s janky in that classic Flash game way, but that’s part of the charm. I still go back to it when I want something simple but chaotic.
