Universal Orlando Resort’s Mine Cart Madness, a cornerstone of the new Super Nintendo World expansion at Epic Universe, is facing significant setbacks as the attraction enters its preview phase. Recently, TikTok user @walruscard shared concerning footage, claiming that the ride was down for an entire day following an alleged accident.

Accident Reported at Universal
According to the TikTok post, the Mine Cart Madness ride was completely out of service on Wednesday, May 7, 2025, with the downtime lasting throughout the day. The user also reported a troubling visual issue, stating: “So many carts missing wheels on Nintendo’s latest ride.” This revelation has sparked speculation about what might have caused the incident and whether the attraction will be ready in time for its highly anticipated grand opening on May 22.
The ride, which is a major feature of Super Nintendo World, is inspired by the Donkey Kong franchise and uses Universal’s “Boom Coaster” technology to simulate the thrilling jumps seen in the video games. However, with the official debut looming, the ride has already seen several operational challenges during the preview period, including unscheduled shutdowns and delays. This has led to growing concerns among guests and fans about the ride’s ability to meet the high expectations for the opening.
