We offer some of the most unique ad placements in the industry to ensure the highest performance.

Since banner ads are still so popular, we added 2 new banner sizes in our latest SDK version (3.9.3 for Android and 3.8.1 for iOS): MREC (300×250) and Cover (1200×628)

  • MREC (medium rectangle) banners are one of the most widely available ad sizes on mobile devices. For this reason, the 300×250 MREC banner tends to be popular with advertisers which can increase publisher earnings.
  • Cover banner is a 1200×628/7 ad that is commonly used in social media feeds as well as for native user experiences.


Interstitial Ads are full-page ads displayed before or after a certain content page or action, such as upon entering a stage, between stages, while waiting for an action, upon exiting the application and more.

The Return Ad is an ad unit which is displayed once the user returns to the application after a certain period. To minimize the intrusiveness, short time periods are ignored.

A Splash Ad is a full-page ad that is displayed immediately after the application is launched. A Splash Ad first displays a full-page splash or loading screen that you define followed by a full-page ad.


A “Native Ad” is an ad without any pre-defined UI, which gives you the freedom to design and control the ad exactly as you want. Using Native Ads, you can design an ad experience that perfectly fits your application’s scene, content, and functionality.

Download the latest SDK version (3.9.3/3.8.1) to get access to all of our available ad units and placements and watch your earnings increase!
