Yeap, you can become a billionaire if you have the vision, EA has this vision, once they purchased Bejeweled from PopCap Games - at the time it was already a success - Electronic Arts managed to push this success even further.
Yet the final challenge was to bring this addiction to the masses, thing that Mark Zuckerberg did and pushed him from the millionaire status to the billionaire. This game was already addictive, once it reached the mobile version it was just a step from making the big hit, I think this was one of the first "freemium game" - you play it for free but only for a limited time, if you wanna play it for hours, you have to pay.
Like any drug, first sample is for free as the thing will do it's marketing by his own, "notification sound" - hey, guess what, you can play it again ...
Recently I've seen the movie, The Founder - amazing film - it shows how vision of a man on a good product can make it big, and so it was with Bejeweled ... I mean Candy Crush.
