Sports betting apps are betting that Americans want to gamble on more than just sports.

DraftKings would love it if you bet on the Knicks game. Oh, and while you're at it, why don't you hop over to its casino app and try out a little online blackjack? And wouldn't it be neat to eventually toss a few bucks on some lottery tickets, too?

While more and more Americans are getting used to wagering on games from their phone, sports betting is just the start. The next step is to get people to gamble on everything.
