It’s really easy. Watch the videos and install free apps from the list provided. Receive Eagles in your account! Want to get even more? Invite your friends, and you’ll get a bonus proportional to what they earn (you will receive 20% of your friends’ earnings, and this is an additional bonus; it is not deducted from their earnings).
It’s a unique offer: you get Eagles to use in the game without ever spending any of your own real money!
