Cash Prizes and the Google Play Store
The Google Play Store’s policy on gambling prohibits “games of skill that offer prizes of cash or other real world value.” This includes War of Conquest. Because of this, the version of War of Conquest that is available through the Google Play Store does not allow players to receive their winnings as cash prizes. Players may still receive their winnings as Credits (the in-game currency).
In order to be able to cash out your prizes, you would need to install a version of War of Conquest that has not been downloaded from the Google Play Store. You can install War of Conquest directly to your Android device by following the instructions found here to install the War of Conquest .apk installation file.
Alternately, you can install War of Conquest on an iOS device from the Apple App Store, or on a Windows using Steam.
