Update #2: OK, we've just finished sending out 2500 Hearthstone beta keys to the winners of the competition. Check your email to see if you've won!

Update: We'll be sending out Hearthstone keys later on today (Monday 16th), but will continue to accept entries right up until we hit the button!

Original story: Blizzard's collectable card game Hearthstone: Heroes of Warcraft is the hottest ticket on PC and Mac right now - and at the moment you do still need a ticket to get in. The publisher plans to put the game into open beta as early as this month but, after the closed beta version proved so popular, it is also keen to polish it up to a diamond shine first, so it may slip into 2014.

The good news is that the company still wants to add people to the closed beta in the meantime, so it has given us another 2500 Hearthstone keys to give away before Christmas. If you would like to get your hands on one, all you need to do is provide your name and email address below (we will not use this data beyond the competition) and next Monday, 16th December, we will send out keys to 2500 random entrants. You can enter your details any time until then.

(Form removed - this competition is now closed!)
