The loyalty program was free to join and provided rewards in exchange for consumer feedback and loyalty to purchasing official Nintendo products.

Rewards included objects such as playing cards, tote bags, controllers, downloadable content, and warranty extensions on select Nintendo products.

Points are also awarded for the purchase of select third-party titles, and can also be obtained by participating in surveys, inviting others to become a Club Nintendo member or even simply visiting a web site.
