@Caudle If you're a fan of puzzle games, there's an android port of Simon Tatham's Puzzles that's entirely free. We've also gotten a lot of enjoyment out of one particular Slitherlink game, though I don't know what it's called beyond just Slitherlink.
When we had an ipod touch years and years ago there was a really good Masyu app on that that's probably still around. Unfortunately it doesn't have an android version.
