Shigeru Miyamoto Explains Super Mario Bros Boss Design
Shigeru Miyamoto, the veteran Nintendo designer behind Super Mario Bros and Donkey Kong, recently spoke at a cultural award event in Japan about a defining design choice in the original Super Mario Bros.
Released for Nintendo’s Famicom/NES in 1985, Super Mario Bros helped popularize side-scrolling platformers and has sold over 40 million copies worldwide.
The game was developed at Nintendo under Miyamoto’s leadership alongside designers such as Takashi Tezuka.
At the event, Miyamoto described how childhood play informed the game’s focus on movement and imaginative action.
He said that, as children, he and his friends would watch the world outside and imagine people running, flying, or falling — a playful impulse that he tried to capture in the game’s mechanics and physics.
Miyamoto also explained the game’s unconventional approach to the final castle encounter with Bowser.
According to his account, Nintendo’s team initially struggled to design a conventional boss battle that fit the game’s left-to-right, momentum-driven flow.
Rather than forcing a standard, staged fight, Miyamoto conceived a solution in which the player’s forward progress itself would determine victory.
He proposed making the goal to reach the far right side of the screen, and devised the bridge-and-axe finish where jumping over Bowser (or triggering the bridge switch) causes the bridge to collapse and defeat him.
Miyamoto said he tried the idea and found it surprisingly fun, and that realization pleased him.
Those remarks reaffirm the original Super Mario Bros design philosophy: simple controls and emergent fun.
The bridge-and-axe resolution at the end of castle stages remains one of the game’s most memorable moments and a clear example of how constraints can produce elegant mechanics.
Super Mario Bros has been preserved across Nintendo platforms since its 1985 debut.
On modern hardware, the original game is available to play on Nintendo Switch through the Nintendo Switch Online service.
Nintendo continues to highlight classic titles in Nintendo Direct presentations and through promotions on the Nintendo eShop, keeping Super Mario Bros accessible to new audiences while underscoring the lasting influence of Miyamoto’s early design choices.
