18 hour non-stop flight

I am wholly unprepared for my impending 18 hour flight tomorrow.

I have been dreading it so I have ignored it.

The Inflight entertainment looks pretty lacking and there is no wifi on this Qantas flight.

My only source of entertainment will be my Google 9 fold, I have signed up to the YouTube premium free trial and downloaded a bunch of videos to watch.

Is there anything else? I don't think the screens big enough to watch movies, but maybe off line game recommendations or something?

Pls help
