The Victory Crown is now available in Solo, Duo, Trio, and Squad matches in Fortnite Chapter 3 Season 1.
The crowns help you get the skins from the Chapter 3 Battle Pass. Before that, you must know what a Victory Crown is and how to get one in Fortnite.

What is this Victory Crown?

Getting the Victory Crown in a Fortnite combat gives you extra XP for the whole match, perfect for climbing the Battle Pass ranks. It unlocks a distinctive emote that shows your total Crowned Victory Royals this season. Fortunately, this takes up no inventory space and may be thrown away if you don’t want the pressure. However, you must first obtain the Victory Crown within Fortnite.
So how exactly to you win a Victory Crown?

There are three methods to win a Victory Crown, the first of which gives you a crown in the battle you’re playing once you’ve earned it.
You must obtain high rank for either the Solo, Dups, Trios, or Squads battle to obtain the Victory Crown using this technique.
The following are the ranks you must achieve:
Top four solo players
Top two teams compete in duos.
Trios – The best team
Squads – The best team
Whether you’re playing Dups, Trios, or Squads, your whole team will get a Victory Crown. Even if you didn’t win the previous game, you’ll get the Victory Crown the following time you play.
The second approach is to assassinate a player who already has one. When they kill an opponent, their name will glow golden. This signals they have now earned a Victory Crown. If you employ these signals, you must be able to identify and kill any opponents with Victory Crowns. When the player is defeated, the Victory Crown will appear amid the treasure, with a golden shine to help you find it.
Finally, when you don’t want a Victory Crown, you may toss it away, which implies you can stumble over a discarded Victory Crown. You can even discover that yet another opponent has just elected to not pick up after killing the Victory Crown opponent.
However, this is not a dependable way for obtaining a Victory Crown, and we strongly advise against depending on it.
