A few days ago Hearthstone Beta was launched in US. Thanks to Europe Blizzard Community Team we are able now to participate in that US Beta testing.
For those who don't know yet Hearthstone: Heroes of Warcraft is the upcoming free-to-play Blizzard game. It's a small card game and for those who are familiar with TCG games it should be easy to understand. I'll try to explain a little bit on how this game works... Hope I wont miss much on the basics.
When you first start the game you'll have to complete a tutorial. That's where you get your first hero and the first cards. As far as I could see there is no way to skip that but I see no reason why someone would skip it...
Your hero is the one casting spells, deploying your troops and the one that has to live in order to win. There are nine heroes/classes: Warrior, Shaman, Rogue, Paladin, Hunter, Druid, Warlock, Mage, Priest. Beside the cards, each hero can use one unique weapon and one unique spell. Leveling each hero will unlock various class specific cards and it seems to increase the health of the hero as well (I might be wrong on this).
Defeating other heroes will reward you with cards as well. Even if your deck can only hold 30 cards, you'll be able to customize your deck however you like. If you want you can buy booster packs (pack of random 6 cards) with real money or gold. I'm still unsure at the moment how you earn that gold. Well, I got some gold when I got my first hero to level 10... Keep in mind that you DON'T have to buy those cards. You can wait and earn them.
Speaking of cards. There are around 300 cards in game at the moment. Each class has 20 basic cards. You should have them all when you hit level 10. As far as I could see Golden cards are the rarest and the most interesting ones. Each hero can use only his class cards and the neutral ones.
Each card has a mana cost, attack points and health. Some of the cards also have special abilities.
After completing the tutorial you'll be able to play against other players. The matchmaking system will select the best opponent for you. By winning those duels you can earn gold or even cards/boosters.
You can Practice as well and test various decks against basic or expert opponents. The expert ones are pretty good as far as I could see...
The third play more is the Arena. There you can forge your own deck from all the in game cards, whatever you have them or not.
We spent a few hours today playing the Heartstone: Heroes of Warcraft and we have a few videos of its interface and a couple of tutorial fights. Hope you'll understand the basics from there.
Let me know if you have any questions about the game. I'll try to answer the best I can.
