World Of Tanks Blitz is not on Google Play Store I am very new to Android ecosystem.  I can't seem to locate this game title on Play Store.  Should it be on Google Play Store?
According to the game's official website, it's available "exclusively on iPhone, iPad, and iPod Touch". The developer has chosen not to release an Android version.

They may do so at a later date. Often with mobile games, the developer will release on one platform first (usually whichever they're most familiar with) to test how much of a market there is for the game, before porting it to the other platform.
