No Ads is a one-time purchase that has no time limit.
You can purchase No Ads by tapping on the 'No Ads' logo in your game.
You can transfer your No Ads purchase to all the devices that use the same Apple ID or Google Play account.
In Popcore games, purchasing No Ads removes all interstitial ads from the game (the ones that you usually see during gameplay or after you finish a level), which means you can continue playing without being interrupted. However, this purchase does not remove ads that provide a reward. For example, you will still have to watch an ad to replay a failed challenge level.
If you’ve purchased No Ads and you are still seeing interstitial ads, please let us know.
