Side-scrolling platformer where you guide Mario through eight worlds to rescue Princess Toadstool from Bowser, who's cursed the Mushroom Kingdom's inhabitants into bricks and plants. Each level scrolls left to right across pits, pipes, and floating platforms. You stomp enemies like Goombas and Koopa Troopas, collect coins, and hit question blocks for power-ups. Mushrooms make Mario grow larger and take an extra hit. Fire Flowers let him throw fireballs. Starman grants brief invincibility. Levels end by jumping a flagpole; every fourth stage swaps platforms for a castle with Bowser guarding a bridge. Miss a jump or touch an enemy while small, you lose a life. The game doesn't hold your hand—timing matters, and some gaps require running starts. Suits players who like precise movement and pattern memorization.
