Music Trivia Apps

I have an android tablet, but it doesn't have the regular android market. And I was really wanting all the music trivia apps for it, so Hubby & I can play them together on a bigger screen. It won't let me get any apps from other websites either that use the original android market to download. Can anyone please tell me how I can get the apk files to them so I can install them? Or if anyone has any of the apk's to them, it would be Greatly Appreciated.
Thanks!

 

But I dont have the apks that will install the trivia games to the tablet. I have them installed on my droid incredible, but I can't seem to find where the apk files got installed on it. That would have made it easy so I could have just copied them to my tablet. I can't even find where the program is installed. I looked in system/app, its not there & I don't see it on my sd card that I have installed. I used astro file manager to try & search for the installed files, with no luck.
