All aboard the coin train. By that I mean you need coins to improve your team in Madden NFL Mobile. Whether you prefer the excitement of opening packs or hitting up the auction house, your squad won't get any better without more coins to spend.
(Or buying in-game cash with real money, of course, but let's say for the sake of argument we're not doing that for now.)
Since the energy system in Madden NFL Mobile can be fairly restrictive, especially in the early going, you've got to plan wisely. If coins are all you love, then that's what you'll receive.
No, wait, that's from Star Wars. But if you want to maximize your coins while playing, here's what you should be doing.
