The rules are simple but finding the Easter Egg's hard. XD You know the instructions already--- Just click a blue button called "See Inside". Oh ya, I remember. Click on my profile picture and then on that blue button named "Follow". It told me that you cannot find the easter egg at all. Smack it and if it turns grey, you are awesome and have the ability to turn grey stars and hearts colorful! Before I forget, I wanted to tell you that there's one more button-- This time it is green. It is called "Remix". Click it, add your own hide the Easter Egg somewhere else and then click on the "Share" button. You'll see it near the title you are going to give to the remixed project. Remember, it can't be the same place or else someone will report your project.
