Hidden Code Reveals Netflix Is Testing TV Gaming With Phones As Controllers
In an interview with Bloomberg News, Moser said one line of code read, "A game on your TV requires a controller to play. Do you want to use this phone as a game controller?"

The current method of accessing Netflix games includes having to download them from either the Apple Store or Google Play. Once downloaded, the games can be launched from within the Netflix app with an active subscription. As of right now, games do not appear on the Netflix app for TV.
Netflix struggled financially all of last year, reporting a loss of 200,000 subscribers in Q1 of last year, and expected to lose 2 million in Q2. The company hopes it can capitalize on the popularity of gaming, and in turn, keep current customers while bringing new ones to the service.
The company has said it has plans to implement a cloud gaming service at some point in the future. This would allow customers to play games without the need of downloading them, and is more than likely the method it will use if it does launch its gaming service on TVs. As of right now, nothing has officially been announced.
It is important to note, that while the hidden code is there right now, it does not guarantee Netflix will ultimately bring games to TVs through its streaming service. It does, however, seem to indicate the company is working toward that goal.
