To install new games on a Motorola cellphone, select the applications tab on its home screen, and open the Play Store app. Tap the Categories button, tap the Games category, and tap a game. If the game is free, tap the Install button; otherwise, tap the Price button.
When the required app permissions screen appears, review the permissions, and tap the Accept button to continue. If the game is not free and you haven't set up a preferred payment method for Play Store, tap the Continue button to set up a payment method. Once installed, tap the Open button to launch the game.
