Hi Susanne,
Welcome and thank you for posting your query in Microsoft Community.
I understand that you wish to play games using Amazon TV fire stick.
I would like to inform that one cannot use Amazon TV firestick with a computer. The Fire TV Stick is a tiny bar that you stick into your HDTV's HDMI port and use just like any other streaming device.
You may contact the Amazon TV Firestick support for more information.
Let us know if you have any further query on Windows, we are glad to assist you.
