Players guide Mario or Luigi through a connected world map containing standard courses, castles, ghost houses, fortresses, and secret areas. The main objective is to reach each stage’s goal and eventually defeat Bowser, while optional exits open alternate routes and hidden levels.

Movement, jumping, running, power-ups, item carrying, cape flight, swimming, and Yoshi riding form the core actions. Progress is saved through the handheld’s save system, and discovered switch palaces permanently alter some stages.

Learn each level’s safe route before rushing toward the goal. Carry a reserve power-up when possible, and use Yoshi or the Cape Feather to explore difficult sections.

Search for keyholes, colored switch blocks, and hidden paths. Completing switch palaces and secret exits can simplify later stages and reveal alternate routes across the world map.
