Super Mario Bros. 35 was a limited-time online battle royale game released in October 2020 to celebrate the 35th anniversary of the Super Mario Bros. series. It was available exclusively to Nintendo Switch Online subscribers and was taken offline on March 31, 2021, as originally planned.
Nintendo did not provide an official statement explaining the shutdown. However, it's common for Nintendo to offer limited-time experiences to commemorate special anniversaries or events, creating a sense of urgency and exclusivity.
While Super Mario Bros. 35 is no longer available, Nintendo continues to celebrate the Super Mario series with other games and events. For example, the Super Mario Bros. Wonder game was released in October 2023, introducing new gameplay elements and characters.
