Blizzard is being very honest with Hearthstone: Heroes of Warcraft in each and every one of the words that make reference to this F2P's letters. It is simple, is addictive, and is completely free, without drawbacks such as having to wait so that it remains just as free or not preclude the extension of your collection of letters for zero euros.
With the announcement of the expansion mode and single-player adventure, the curse of Naxxramas, it was feared that they would pass the stripe and start charging for content, but no, a wide-ranging expansion is still free (with options to pay to expedite the release process), and here the less take stock of such game coins to avoid having to pay real money is not a repetitive exercise of hogs or turns to the same circuit, but that just play as always has played, only saving coins for this expansion and not to buy envelopes or participate in the sand, but Oops, seems to be worth.
