Final AdDuplex challenge of the year to win Windows Phone device of your dreams


Special December Challenge.

This is 10th and final AdDuplex Every Phone They Make challenge of the year. We’ve reached our goal and gave away every possible Windows Phone device that we could find in the market. So with regard to this festive challenge we decided that you will be the one who chooses the main prize of this month.

We will randomly pick one lucky girl/guy and literally let him choose a Windows Phone device of his dreams (considering territorial accessibility). To get one step closer to your dream all you have to do is just tweet or retweet this post:


Challenge will end on the 31st December. Good luck!


Publish Your App Competition.

As always we have two more Windows Phone devices to give away. To express the gratitude to developers that start cross-promoting their apps and games on AdDuplex network we have prepared Lumia 630 and Lumia 635 as these devices seem to be most desirable ones.

To be eligible to win in this challenge all you have to do is start using AdDuplex to promote your app for free and you are automatically entered into the draw. All submissions have the same chance of winning as the lucky ones will be randomly selected.

Submit your apps and games by the end of December and take your chance to become a winner of final challenge of the year.

Check out the official rules.
