Hearthstone

The Amazon Appstore version of compulsive card battler Hearthstone is offering a limited time deal right now: spend $20 or more on card packs, and you’ll get Amazon Coins worth 30 percent of the amount you spent.

You can the use those Amazon Coins for stuff in the Amazon Appstore, which includes even more Hearthstone card packs. So if you spend $100 on cards, you'll get $30 to spend on other games, apps, or more cards to feed your insatiable habit.

If you've got a Kindle Fire, then you can get Hearthstone from the store. If you've got another Android, you'll need to download the Amazon Appstore first, and then get the game.

This offer is only available to customers in the United States, United Kingdom, and Germany.
