That new Hearthstone game mode Blizzard was teasing on Twitter has been revealed: Tavern Brawl!

Tavern Brawl is a weekly event that lets players engage in versus matches with unique rules applied.

Blizzard provides a few examples of these rule changes on its blog.

They include preset decks and buffs that only apply to specific minion types.

Just like a real tavern, there is a requirement to get in - you must be at least level 20.

You can play Tavern Brawl with strangers or challenge your friends.

Perhaps to encourage this, Blizzard has also raised the friends list limit on battle.net to 200.
