There is not a playable version of "Super Mario 64" online. In March 2015, developer Roystan Ross released a playable online version of "Super Mario 64." However, shortly after its release, Ross received a copyright infringement notice forcing him to shut the project down.
News websites, such as Business Insider and Time, reported the game's free online availability, giving Ross credit for its development. These sites also received notification to remove the game's web player from their articles.
MuchGames.com claims to have a playable online version of "Super Mario 64," but when the user clicks to play the game, the title "Super Mario 63" appears.
