I currently have a separate layout for interstitial ads and a interstitial global counter.
Layouts:
1. Preload
2. Game
3. Shop
4. Interstitial
Every time the user clicks back it adds 1 to the interstitial global counter.
When this counter reaches 2 it takes them to the interstitial layout and resets the interstitial global value to zero
My question, is there any need for the interstitial layout at all?
Is it best to just show the advert over the Game layout?
