Pool

Pools are a feature in Splatoon 3 that can be accessed in the Battle Lobby.

Description
Similar to Private Battles, Pools are groups a player can join or create by inputting a passcode or generic sentence. When a player joins a Pool or creates one, they will get notifications from other players in that Pool. Players wanting to play game modes such as Turf War and Tableturf Battle can notify their friends and Pool members to play a game.

The player can leave Pools at any time; however, they can only join one Pool at a time.

Quotes
"Switching gears... we've discovered a new feature that helps players connect. It's called a Pool, and anyone can join one by inputting a unique set of letters or characters. You can send and receive notifications with others in your Pool, and even invite them to join a battle!"
