Tower Defense

As perfect as Bloons TD is, there’s room for another tower defense series in your life, and it should be Kingdom Rush. This medieval fantasy world is overrun with monsters, and you are just the hero to slay them by building defensive towers (archers, mages, artillery, and infantry). A super cute comic book style and humorous vibe that reminds me of Dungeon Keeper detracts from the wanton violence, making this suitable for any mobile gamer. There are five main games in this series—Kingdom Rush: Alliance (iOS, Android) is the latest, released this year—and they are all beautifully made, deeply addictive, and genuinely challenging.
