How to find out which games have demos, and how to download them via the official Nintendo website
Our games search allows you to filter by system and for games that have demos – select those options and you'll be provided with a full list of relevant titles. Alternatively, you can refer to this list of all games for which demos are available.
All demos for Nintendo Switch, Wii U and Nintendo 3DS family systems can be downloaded directly from this website, provided you have a Nintendo Account. Simply locate the 'Download demo' button on the gamepage and click it. For certain demos you'll pass through a purchase process as if you're purchasing a free product. For other demos, clicking the button is all that's needed to begin downloading the demo on your system immediately.
Please make sure you have enough storage to complete the download.
