Nintendo Switch Online (NSO) is an online subscription service for the Nintendo Switch video game console. Nintendo Switch Online features include online multiplayer, cloud saving, voice chat via a smartphone app, access to a library of Nintendo Entertainment System (NES) and Super Nintendo Entertainment System (SNES) games, as well as other promotions and offers. Following an interim period where Nintendo offered online multiplayer free of charge, the subscription service officially launched on September 18, 2018. The service is Nintendo's third generation online service after Nintendo Wi-Fi Connection and Nintendo Network. Reviews for the service were mixed. Its affordable price compared to other online services was generally praised, but its smartphone app, NES content library, small selection of cloud save-supported games and lack of dedicated servers were criticised.
