Super Mario Bros. Wonder Leaks Online Days Before Release, Latest in String of Nintendo Switch Game Leaks

Super Mario Bros. Wonder leaked online 6 days before its October 20 release date. This follows a pattern of Nintendo Switch game leaks.

Nintendo took strong action after the Zelda Tears of the Kingdom leak, but it continues.

Leaks fill the internet with spoilers, ruining surprises for fans before release. Unplugging may be required to avoid Wonder spoilers.

Pre-orders are open for Super Mario Bros. Wonder at major retailers.
