A single Nintendo Switch console can support up to eight players in Super Smash Bros. Ultimate.
Super Smash Bros. Ultimate was released on December 7, 2018. Its multiplayer modes allow several players to use Joy-Con controllers, Nintendo Switch Pro Controllers, or compatible GameCube controllers through an adapter. The exact controller setup depends on the match and the accessories available.
Eight-player Smash is a local multiplayer format, not the normal maximum for every mode or online match. The game’s rules can be customized with different stages, items, time limits, and stock settings. Some stages are designed with large groups in mind.
The eight-player figure is often confused with the four-player limit common in earlier multiplayer games or with the number of players supported in a particular online battle. Ultimate’s local multiplayer support is one of its major party-game features.
