UPDATE #2 All winners have now been notified and the beta keys distributed. Congratulations to our winners! If you weren't lucky this time around, we hope to have another giveaway for you in the near future.

UPDATE: The competition is now closed! Winners will be notified directly via the e-mail provided in the competition entry form. We will update this article when all keys have been distributed.

At some point in the not-too-distant future, Blizzard plans to release its highly anticipated card game Hearthstone: Heroes Of Warcraft on the App Store. Before that happens though, the game will be officially released for the PC - and having spent some time getting stuck into the game's superb strategic card combat ourselves, let's just say you'll want to get some practice in ahead of the iPad launch.

Hearthstone is currently in closed beta, but Blizzard is offering 100 Modojo readers the opportunity to join the PC crowd who are already playing and testing the game. In order to be in with a chance of winning one of these beta keys, simply fill out the form below and provide us with an e-mail address we can send the key to, should you be successful.

The competition closes at 5pm GMT on Monday 11th November, at which point we'll use a fancy random number generator to pick out 100 winners from the pool of entries. Those winners will then be notified via the e-mail address provided, so please make sure you've given us a valid one. On that note, rest assured that we will never share your contact details with any third-parties.

To keep up to date with all of our competitions - not to mention all of the mobile gaming reviews, news and previews worth knowing about - you can follow us on Twitter, or join our community on Facebook.

Good luck!
