TSTO on Kindle Fire

I play exclusively on a Kindle Fire (HD 7"). I don't need wait for the "Update" button to appear as others do. When I hear there's an update, I just reboot and I usually get it. There's only been a few times when Amazon was behind for me.

Edit: Oh! And TSTO is a memory hog on Kindle. Reboot your device at least every 1-2 days, or you will get funky blank screens on TSTO. It's a good idea to do if you use your Kindle a lot anyway.
