SaxonRah knows what’s up!
Not to disparage the effort Epic are going to with these jams, but while prizes are always a sweet incentive for people to join, gamejams should not be about “winning” - to me, a gamejam is about making something cool, proving to myself and the world that I can make something cool, and having a fun time with my team. They’re an opportunity to learn and try new things, let your creativity run wild and make some crazy-*** wacky stuff that would never get past a marketing board 
There are no stakes in gamejams, so while it’s to push yourself and experience the pressure of finishing something with a very tight deadline - try not to get distracted by the prizes, guys! You’re robbing yourself of a great experience if you’re just doing this to win
