Super Mario Bros. 3
超级马里奥兄弟3
Super Mario Bros. 3 is a side-scrolling platformer developed by Nintendo in 1988 for the NES. Players control Mario as he travels through eight worlds, each with multiple stages, fighting Bowser's army to rescue Princess Peach. The game introduces power-ups like the Tanooki Suit, which grants flight and temporary stone transformation, and the Frog Suit, enabling underwater movement. Mario can also crouch to enter pipes, swing from vines, and grab flying enemies. Each world presents different environments—forests, deserts, oceans, and castles—with increasing difficulty. The level design balances exploration with challenging platforming sequences. Players use directional controls to move, jump with the A button, and run with B. The game supports alternating two-player gameplay, with each player completing worlds in turn.
