A. DOWNLOAD NON-AMAZON APPROVED APPS
Some mobile poker rooms like 888, PKR and Bitcoin only poker sites have released native poker apps that need to be downloaded and installed on your Kindle Fire. Since you won't find any kind of real-money gambling app in the Amazon App Store, you'll need to download them directly from the poker rooms website for following these instructions.

1. Go to Settings > Device and enable Allow Installation of Applications From Unknown Sources.
2. Now browse to the Android poker sites like PKR Poker or 888 and you should automatically be prompted to install their native poker app.

B. PLAY POKER ON YOUR AMAZON KINDLE FIRE BROWSER
Fortunately, not every mobile poker app requires you to commit to a download – in fact, many apps are going to load directly from your browser, which means that you can play them on your Kindle Fire without any issues. Keep in mind that most of those apps are based on the HTML5 technology, which means that they work best with the Google Chrome web browser. Consequently, if you experience any problems loading the poker apps provide by the sites listed here, you should definitely consider installing Google Chrome using one of the many online guides. Below, you will find basic information on some of the best Kindle Fire compatible mobile poker sites.
