An excellent free online card game set in the Warcraft universe
Hearthstone is a wildly popular online card game released by Blizzard Entertainment. The game takes place in the Warcraft universe, with cards based on popular monsters and heroes from the game universe.
Hearthstone is nothing less a phenomenon. It's a wildly popular game, designed by a studio not known for making games in the genre. It combines the polish of a Blizzard game with the addictive qualities of a collectible card game, and it does so seamlessly. It's a game that anyone can pick up and play, and it doesn't cost a dime. With time and effort, you can unlock anything the game has to offer. All you need to do is figure out how to play.
The downsides are two-fold, though. First and foremost is the learning curve. Hearthstone is easy to understand, but winning is an entirely different story. The metagame of the game is constantly changing, so you'll never quite know what's going to win unless you spend time reading up on the topic. You'll also encounter players who have vastly better decks, usually because they've spent real money on cards. If you are playing for free, you'll simply never outdo those who pay to play.
Hearthstone is a solid collectible card game, with all the pros and cons that come with the genre. It's a great game that can run on almost any computer or device, and it's probably worth playing a hand or two to see if it's for you. After an hour or so, you'll either throw the game aside in frustration or find that it's become your new obsession. Either way, it will certainly be an experience for you to remember.
