Play Mario Brothers Online
You run through sewer pipes smacking platforms to flip turtle-crab hybrids, then kick them off before they wake up—the POW block clears the screen when things get messy, but only works a few times.

Mario Bros. came out for the Nintendo Entertainment System in 1983, developed and published by Nintendo. It was one of the earlier games on the platform, a straightforward arcade-style experience that felt right at home on the console.
You control either Mario or Luigi, clearing out pests from the sewers one screen at a time. The main goal is to defeat all enemies on each stage by hitting the floor beneath them to flip them over, then kicking them away before they recover. Two key mechanics are the POW block, which stuns all on-screen enemies when hit, and the ability to collect coins that occasionally appear. The pacing is quick and the difficulty ramps up steadily as more aggressive enemies appear. It feels like a tense, rhythmic puzzle where timing every hit and dodge matters.
