I cannot purchase the user made games

the user made games are not available on the amazon app market and that is the only one I have access to.

“Hosted Games” are only available on the Android, iPhone and Chrome Web Store markets. I’d suggest trying the latter, you only need a desktop computer capable of running chrome.

I do not have any way of accessing that. TwT All I can use is the kindle
