As one of its daily deals, the Amazon Appstore for Android offers downloads of Magic Marble In Space for Android
. That's $1 off and the lowest total price we could find for this musical game in which you try to keep a rolling marble on a path. Deal ends today.
If you haven't claimed it yet, you can receive a $1 Amazon MP3 Credit for free with this download. (It can only be claimed once per Amazon account until December 31.)
