To celebrate today's launch of the Galaxy S6 and S6 Edge, Samsung is giving away 8 devices to fans in the U.K. But to get yours, you'll need to find one of 8 golden envelopes that are hidden in cities throughout the country.

"Throughout the day we will run a hunt an hour in our chosen cities. The first clue will be a live stream from the venue of a hidden Golden Envelope," Samsung explains. "Then there will be a further 4 clues tweeted to help you find the location."

Here are the cities where the envelopes will be hidden, and the times at which they'll be available:

  • 10:00 – Glasgow
  • 11:00 – Edinburgh
  • 12:00 – Belfast
  • 13:00 – Leeds
  • 14:00 – Liverpool
  • 15:00 – Birmingham
  • 16:00 – Cardiff
  • 17:00 – London

If you're in one of these locations and you manage to find a golden envelope, there will be final instructions inside that will allow you to claim a brand new Galaxy S6 absolutely free. But don't worry if you cannot get to one of these cities.

"If you figure out one of the hidden locations, simply tweet your guess using #GS6isHere and if you are correct you go in to a prize draw for a chance of winning a Galaxy S6," Samsung says.
