I have free Google Play credit from buying the Nexus 7 last year that expires at the end of this month. I'd like recommendations for paid Android apps so I can spend it all. I'm not rooted and have no interest in rooting, so stock apps, preferably games, are what I'd like to buy (ideally for both phone and tablet). Don't need media players or productivity apps (unless Tapatalk is that useful). I'll consider non-games if it's something pretty cool. For example, I bought a koi pond app and am looking into an aurora live wallpaper (after my ice hotel inspiration), I call these "chill" apps.
