Chambara

Chambara is a sport that first appeared in Wii Sports Resort, known as Swordplay in that game. It reappears in Nintendo Switch Sports. In Resort, it supported 2 players for Duel and Speed Slice, and 1 for Showdown. In Nintendo Switch Sports, it will support 1v1 locally and online.

Wii Sports Resort
Players can play in Duel, Speed Slice or Showdown. In duel, players must knock their opponent off the edge in a best out of three match. If the players are tied after three rounds (which requires either three draws or both players winning one and drawing one), a final round appears where the playing field gets smaller. If that match ends in a draw, the whole game does too.

Nintendo Switch Sports
The rules stay the same as they did in Wii Sports Resort, but now the sport is renamed to Chambara. There are three versions of the sword used in this sport: Sword, Charge Sword, and Twin Swords. The regular sword has the most powerful attack, the charge sword has the ability to strengthen attacks via guarding, and the twin swords allow players to dual wield and perform a powerful Spinning Strike.
