Hi Valerie, it depends on which state you're based in.
"Individuals who are at least the age of majority where they reside at the time of entry (“Eligible Individuals”)"
For example, if you're based in New York you'd need to be 18 by the time you enter to be eligible for prizes. We will be continuing these throughout 2021 as well so if you wanted to make something and enter submission when you're 18 if required by your state then that would work. Let me know if that helps clarify!
