Which Nintendo Switch game introduced the virtual sports facility called Spocco Square?

The Nintendo Switch game that introduced the virtual sports facility called Spocco Square was Nintendo Switch Sports.

Nintendo Switch Sports launched on April 29, 2022. Its main hub, Spocco Square, provides access to sports including tennis, bowling, chambara, soccer, volleyball, and badminton. Golf was added later through an update released in November 2022.

The game uses motion controls through the Joy-Con controllers, continuing the broad idea of motion-based sports play associated with the Wii Sports series. Players can compete locally, online, or in organized online modes depending on the sport and feature.

Spocco Square is not the name of a separate console or accessory. It is the in-game location that connects the sports activities. Nintendo Switch Sports also introduced customizable player avatars and online progression systems distinct from the older Wii Sports presentation.
