The Nintendo eShop storefronts for both 3DS and Wii U will shut down for new purchases on 27th March 2023.
This closure extends to in-game purchases made outside of the eShop app on these platforms, such as within the 3DS’ Nintendo Badge Arcade.
Nintendo confirmed the date today, and reminded 3DS and Wii U owners that the 29th August 2022 deadline for adding eShop card funds was now approaching.
