EA is having a creating competition for people to create an iOS, android or Windows game or app. Which is cool. Bunch of teams get together, and they have 14 hours to create something, and have a 3 minute presentation ready for EA to judge. Only thing is if you make something they like, whether it be a brand new game mechanic or a way to monetize in the game, EA has the right to use it in any of their games for free, without paying the creator(s) royalties.

Before you register, read the fine print. There is a lot of legal language of which you should be aware. While your creation remains your property, any physical submissions become the property of EA. Furthermore, anything you create during the Code Wars event can be used by EA under a royalty-free, irrevocable, but non-exclusive license.
In other words, if you come up with the next great game mechanic or monetization scheme, EA can use it throughout its portfolio without paying the creator a thing. You can license it to others and use it yourself without a problem, but you also wouldn’t be able to collect fees from EA’s use of your idea.
Additionally, EA cautions that its own studios might already be working on something similar. There is a chance that your great idea might not be that unique, in which case you might not even be able to license it out because of EA patent filings.
