Players view each course from a side-scrolling perspective and must reach its goal while avoiding enemies, hazards, and pits. Mario or Luigi can run, jump, stomp enemies, collect coins, and use power-ups such as the Super Leaf, Tanooki Suit, and Frog Suit.

The Mushroom World is divided into themed areas connected by a map containing standard stages, fortresses, bonus games, and airships. Completing stages opens routes toward each area’s castle, where a Koopalings battle must be won. Inventory items and map events provide alternate ways to approach progression.

Learn each stage’s enemy patterns before committing to long jumps, and keep a reserve power-up in the item inventory for difficult sections.

Explore suspicious walls, pipes, and open spaces. Coins, hidden blocks, warp whistles, and map items can reveal shortcuts or improve your chances against fortresses and airships.
