: Unlike many Switch games, Dr. Kawashima's Brain Training relies heavily on specific hardware. Many exercises require the IR Motion Camera (found only on the right Joy-Con) or the included Stylus . If you are using a Switch Lite or a third-party controller, the "free" software experience will be incomplete and often unplayable. Why Dr. Kawashima’s Brain Training is Worth the Purchase

: "Free" download sites are notorious for hosting files bundled with malicious code. These can compromise your PC during the transfer process or even damage your Switch’s operating system.

: Nintendo is highly efficient at detecting modified consoles. If you connect a Switch running pirated NSP files to the internet, you risk a permanent ban from the eShop and online play.

: Subscribers often get access to classic puzzle games that offer similar cognitive benefits.

: Nintendo frequently includes first-party titles in seasonal sales.
