乱斗模式（Tavern Brawl）是《炉石传说》的四大模式之一。Tavern Brawl is one of Hearthstone's lighter game modes. A weekly event, a new Tavern Brawl begins each Wednesday (Thursday in Asian regions), ending the following Monday. Outside of these times, the mode is not available for play. See the schedule for this week's times.
Each Tavern Brawl presents a limited time opportunity to face other players in special matches with unique rules. These might be requiring players to use special pre-made decks, adding random cards or minions, or changing the very rules of ability activation or mana use. Some Tavern Brawls allow the player to construct special decks especially for the challenge from within the game mode itself, while others provide powerful premade decks, or even entirely random decks, and some Brawls even see players take control of special heroes with their own Hero Powers. Some Brawls feature Tavern Brawl cards, special cards not available in other types of play, as well as boss cards from adventures such as One Night in Karazhan. Each week sees a fresh Tavern Brawl, with its own unique rules.
As well as being matched against other random opponents, players are able to challenge players on their friends list to a Tavern Brawl, as a special type of Friendly Challenge.
An intentionally "fun" game mode, Tavern Brawls offer unique limited time experiences, with far less of a competitive focus than other game modes. This makes them good for quick matches, friendly games and accumulating gold through quests and cumulative wins. With many Brawls incorporating random card generation or minion summoning, winning a Tavern Brawl often involves a fair amount of luck, as well as the ability to adapt to and deal with the situation at hand. Tavern Brawls help to break up the focused rigours of Hearthstone's other game modes by providing a fresh twist on the game's rules each week.
Tavern Brawls are intended to be highly accessible, even for players without extensive card collections. However, Tavern Brawls are not unlocked until the player reaches level 20 with at least one class.
