Its a fire device or whatever the fuck its called, how the Hell do I bypass this without buying a new device

Have you updated your device? I'm pretty sure the app store was discontinued but updating can help check.

I managed to fix it, I just gotta reinstall the games

Fire OS is Android
Just install Play Services and the Play Store and you are good to go

I sadly can't

One option is called sideloding but I don’t really know how that works since I have an iPhone and Apple doesn’t like it when people don’t use software thats not in their appstore. From what I hear, basicallyyou need to download a different unofficial webstore where stuff may not be verified. It will be slightly more dangerous.

Your other option is probably downloading google play.
