I also like Everybody Edits because you can create different worlds there and share it to other players or even your friends. You can also get new friends in that game. You can buy new blocks, smileys (smileys are your avatars or characters) with different emotions, and new worlds using your energy (you recharge one energy every 2 and a half minutes).
When you get a coin there is a chance to get a magical one! Each magical coin increases your maximum energy depending on what you will get. You can only get +1 energy with minor magic coins. +2 energy with normal ones. +15 with rare ones (rare magic coins also replenishes your energy to full). You can also get smileys from magical coins like the "Grinch smiley," the "blue and red wizards smiley".
