Nice! So ios wont be until a few more months? Here is what it said in the article :

"According to Gary, Dark Legends will be in beta within two months, then will release first on the Kindle Fire, then Android, then iOS and the Chrome browser soon after that."

So, to conclude from this, Dark legends will be a kindle fire exclusive for 2 weeks, the the android beta, then "ios". so effectively, ios will need to wait until April/May.
