Apple is about to hit another huge milestone, and once again they’re giving away a pretty sweet prize in celebration.

This time, it’s 50 billion App Store downloads that’s fast approaching, and the person who puts them over the top is going to win a $10,000 App Store gift card.

“As of today, nearly 50 billion apps have been downloaded worldwide. And we couldn’t have done it without you. So we want to say thanks. Download the 50 billionth app, and you could win a US$10,000 App Store Gift Card. Or download one of the first 50 apps after that, and you could win a US$500 App Store Gift Card,” says Apple.

In order to be eligible for the prize, you have to be at least 13 years old. And you can only be “entered” 25 times per day, which means that you only have 25 chances that the app you’re downloading is going to be the 50,000,000,000th. It’s like winning the lottery, but hey – you’re going to download apps anyway, might as well give yourself a chance to win a ton of iTunes money.

This isn’t the first time that Apple has offered such a prize for an App Store milestone. A little over a year ago, in March of 2012, Apple hit 25 billion App Store downloads. And they gave away a $10,000 App Store gift card then as well – to a Chinese man who downloaded the popular puzzle game Where’s My Water.
