Play Mario Bros. Classic Online

Mario Bros. Classic came out for the Nintendo Entertainment System in 1983, developed and published by Nintendo. It was one of the early titles that helped define the platform, a straightforward arcade-style game that felt right at home on the NES.

You control either Mario or Luigi, clearing out pests like crabs and turtles that crawl up from the pipes. The goal is to knock enemies over by hitting the platform beneath them, then kick them off the screen before they recover. You move from one fixed screen to the next, dealing with faster spawns and trickier enemy patterns as you go. The pace is quick, and the difficulty ramps up steadily, especially when playing with two people and accidentally bumping into each other. It feels frantic but fair, a game of reflexes and coordination that stays engaging even after many tries.
