Deca Tower

Deca Tower is the central tower in Inkopolis Square in Splatoon 2. Similar to Inkopolis Tower in Splatoon, it serves as the game's Battle Lobby.

Once inside the Deca Tower, the player can play Turf War, Private Battle, join friends, and play Ranked Battle if they have reached level 10. They can also play League Battle once they have reached the B- rank in any Ranked game mode.

Trivia

 * The name could be a reference to the decimal unit prefix of the same name which means "ten" and the number of tentacles a squid has which is also ten.
