Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
What exactly are you doing that produces three stars?
If it is the initial set-up of your Kindle Fire device, then there are instructions in detail, off the list of links on this page:
First, you Register it, with Amazon.com and your account with them... so that it is then 'yours' as opposed to an unclaimed and unregistered device.
Then, you charge the battery fully (though I would have thought that would come first, really.)
Then, you can configure the device with your Email settings, a date-and-time setting that matches your local time zone, or Parental Controls, etc. etc.
Let me know the specifics of the 'three stars sparkling' step - what you're trying to do, etc. - and I will guide you more specifically.
What Android version is on your handheld device, please?
And, what version of Sugar Crush are you playing, please?
The two may not quite be compatible, in which case a slight update of your Android OS might hopefully be all that is needed... to explain why I ask those two questions.
Try observing the Game's startup screen.
Or, in the game, go to
