Okay, some of you may or may not realize I enjoy pnp (print and play) games.  PNP games are files (some free and some you need to buy, hey game designers need to eat too.) that you print out and assemble into a reasonable looking game, although not they not look professional looking.  Earlier this month I bought an Android phone (okay I'm a little behind the times, previously I had a "dumb" cell phone).  I found several pnp games I know of through BoardGameGeek to have apps for the Android and are pretty decent conversions at that.  Games I'm referring to are 'Jasper and Zot', 'Free Trader', 'Yugoslavia 1941', 'Cheese Chasers', 'Maquis', 'Solo Dungeon Bash', 'Super Delve', 'Escape of the Dead',  and 'Castle Builders' to name a few.  There are a few others I don't have yet.  Of course all of these are available at the Google Play Store with the exception of Super Delve, which I got the link for from the developer over at BoardGameGeek.
