Its very simple! First when u log on, you will see a ecoin floating on top of the right side of your screen. Then, click it and it should say click to earn ecoins! It should have choises for you. It should say watch a 20-30 second clip video and then watch it! AFter you will receive 20-25 ecoins! Hoped this helped!
Another way is to log on and you will get 500 ecoins and 3 rubies. At least if you don't go on it too much
