Review on GreedyGame by Donald Waller

I have used it in my game development projects with Unity3d where ads were needed quite often so this one was very helpful! It supports all major mobile platforms as well which is great because you don't need additional software like Unreal Engine or something else when developing games that will be available outside of Google Play Store (iPad/Android).

The price can get high if your project size grows larger than 50Mb limit but there are free versions out already too - check them before spending more credits though :) Highly recommended tool overall since they support most popular devices without any issues at least from what we've seen during our work experience using Ggrey Game Ads Library together withe other libraries such us unityAdsLibrary etc..
