Nintendo eShop sales:
Also new this week:

In addition to video games available at retail stores, Nintendo also offers a variety of content that people can download directly to their systems. Nintendo adds new games weekly to Nintendo eShop on the Nintendo Switch console, the Wii U console and the Nintendo 3DS family of systems.

Nintendo eShop is a cash-based service that features a wide variety of content, including new and classic games, applications and demos. Users can add money to their account balances by using a credit card or purchasing a Nintendo eShop Card at a retail store and entering the code from the card. All funds from one card must be loaded in Nintendo eShop on Nintendo Switch, Wii U or the Nintendo 3DS family of systems, but can be used in any Nintendo eShop if the systems are linked to a single Nintendo Network account.

The Wii Shop Channel offers games and applications and uses Wii Points, which can be purchased via the Wii Shop Channel.

Remember that Nintendo Switch, Wii U, Wii, New Nintendo 3DS, New Nintendo 3DS XL, Nintendo 3DS, Nintendo 3DS XL, and Nintendo 2DS feature parental controls that let adults manage some of the content their children can access. Nintendo 3DS players who register a Nintendo Network ID gain access to free-to-start games and free game demos from Nintendo eShop, and also get the latest news and information direct from Nintendo. For more information about this and other features, visit http://www.nintendo.com/switchhttp://www.nintendo.com/wiiu or http://www.nintendo.com/3ds.
