The Powerpuff Girls Smash game is currently released in limited countries in Asia and Southeast Asia in both Apple App Store and Google Play Store. If you are not in those countries or do not have an app store account in those countries, then you will not be able to download at the moment. There are plans to add additional markets and if you are interested in playing this game, feel free to let us know at helpcenter@sundaytoz.com and we will consider making it available in more markets outside of Asia.
