Have it on my iPad 4 and there it was temporarily free, I grabbed! Posted on as long as the campaign runs. Of course, only for Kindle editions. Because I also have the two Fire models and naturally wanted to take the same graphic differences visually. Kindle devices are top and the graphics can be put on high also. anyone claiming you could only on low. Get out of the game and press the Options wheel on the top right. Video and sound and high. That's it. Runs amazingly well on the Kindle HD. Game's Top and the 7 version he a 5 star award value.
