Welcome to the biggest contest that we’ve ever organized!

We have recently announced a release of our new feature and from now on we are serving interstitial ads. This is a big step forward for AdDuplex and we are sure it will help you get even better results while cross-promoting your apps and especially games. Therefore we’ve prepared something special for you.

We are running a sweepstakes to win an all expenses paid trip to GDC Europe and gamescom conferences that are taking place in Cologne, Germany in August.

GDC Europe is the largest professionals-only game industry event in Europe. It will be held in conjunction with gamescom, the leading consumer show, creating a full week of activity and opportunity for the games industry. GDC Europe is the essential platform for learning, inspiration and networking for the creators of computer, console, handheld, mobile, social, and online games in Europe. So this will be a huge event and our users have a chance to attend it on us.

The rules are very simple: every Windows Phone developer who adds interstitials to their apps and games until the 15th of June will be automatically entered into a draw to become a winner. We will randomly pick and announce the lucky one on the 1st of July.

Moreover, everyone who adds AdDuplex interstitials before the end of February, 2015 will get a permanent 90% exchange ratio (as opposed to the regular 80%). This means that you will get 10% more impressions than other developers.

The winner takes it all:

• All Access Pass to GDC Europe and gamescom conferences (€895 value)
• Up to €2,000 for travel and accommodation expenses
• €500 pocket money

The conferences will take place in Cologne, Germany on 3-6 of August, 2015.

So book the date in your calendar and sign up to add interstitials to your Windows Phone apps and games.
