The newest expansion pack for the popular digital card game “Hearthstone” is live now, according to developer Blizzard Entertainment. Blizzard tweeted early Tuesday afternoon that players in North America, Europe and Asia could start opening card packs for the “Rastakhan’s Rumble” expansion.

Since it is launch day, there is always the possibility that the game will not work 100 percent correctly right away.

The troll-themed expansion brings 135 new cards to the competitive, collectible card game. Anyone who boots up “Hearthstone” with the expansion gets six free card packs, so they can build a deck and jump into the fray using the new cards.

Aside from bringing new cards to “Hearthstone,” the “Rastakhan’s Rumble” expansion adds a new single player mode called Rumble Run. As always, players are free to buy more card packs with real money if they are not satisfied with their decks.
