Super Mario Bros – World 3-1

  • Level type: Overworld
  • Time limit: 300

World 3 turns the lights off. The sky is black, the ground is dark blue, and the level is otherwise a familiar overworld stage with a 300-second timer. The palette does not change how enemies behave, so play it like 1-1 with more traffic.

The new threat is the Hammer Brothers near the end. They stand on brick ledges and throw hammers in a high arc, and there are two of them, one above the other. Running underneath while the hammers are at the top of their arc is faster than fighting. Fireballs also work, and a shell kicked into their ledge is the cleanest solution.

A pipe in the first half leads to an underground coin room, which is an easy way to top up before the harder stages ahead. The flagpole is reached by the usual staircase.
