Sony's teamed up with UK artist Tinie Tempah in a promotion titled "A Demonstration of Play" which features an interactive video.

Using your phone or your mouse, users are asked to spot the seven hidden triangle, circle, x and square symbols to unlock chances to win a PS4 and tickets to Tinie Tempah in concert. You'll also gain access to trailers for Watch Dogs and DriveClub, two games coming to PS4 in 2014.

You'll find the interactive video here.

PlayStation 4 launches in the UK on November 29.
