You'll need to use a credit or debit card, or PayPal linked to your Google account to complete the purchase.  You can also use any Google credits you have on your account. It is highly recommended that you try a free version of a game first if possible to make sure the app runs well in BlueStacks (many apps don't). If the game requires any special permissions, click Accept to allow the game access to features it needs. If the game you want to install isn't in the Google Play Store, you can install it using an APK file, just like you would on an Android phone.  Use the following steps to install an APK file:  Download an APK file to your computer. Click the icon with three dots ( ⋮ ) next to "Installed Apps" in the upper-left corner. Click Install APK.. Select the APK on your computer and click Install.
