Hearthstone is an online CCG (Collectible Card Game) similar to games like Magic: The Gathering and Card Wars – Adventure Time. It’s fun to play and can be compelling with its simple rules, fast gameplay, deep content, graphics, and animations. The game has to be played online even if playing against the computer and not against a live person. The game is free to download to play, but additional cards can be bought with real money. You have to use your witts and can beat your enemy just by out thinking them.
