Hearthstone currently lacks in comparison to traditional card games is the simple portability of a deck of cards, but that deficiency will soon be rectified. A new update on the official site shares an infographic with players and talks turkey on the upcoming clients for iPhones and Android phones.
The client for Android tablets is nearly finished and should be ready before the end of the year; the iPad version softlaunched last spring. But the iPhone client is taking just a little longer to polish up. As a result, the clients for these devices will not be ready until early next year. So you won't be able to bring the game with you on your phone to winter holiday gatherings in 2014, but before long, you'll be carrying an entire deck of cards in a device that is smaller than an actual deck of cards.
We've included the game's playerbase infographic below.
