Known for console and computer heavy hitters like Civilization V and XCOM: Enemy Unknown, Firaxis’ latest strategy game is the unexpectedly kid-friendly and cartoonish Haunted Hollow for iPhone and iPad. Starring familiar monsters like vampires, ghosts, and witches, this free-to-play game offers a surprisingly rich level of depth and enjoyment that is sure to please any fan of the genre.

Angry Birds Friends brought the fowl-flinging sensation to Facebook, and unsurprisingly, it proved hugely popular in that format. Now the socially-connected spin on the franchise makes the return trip to iPhone and iPad while maintaining the distinct, free-to-play approach that defined that browser-based take. On a platform that already hosts five distinct Angry Birds games packed with several hundred total levels, the prospect of playing in one six-stage tournament per week may not seem remarkable, but it's the competitive aspect that puts an interesting tweak on the usual formula.

Twitter has long been a way for musicians to connect with their fans, but the standalone Twitter #Music app is something different: It's an opportunity for the social networking company to leverage its ubiquitous service to turn users onto new artists. The glossy iPhone and iPod touch offering pulls data from tweets and trends to build visual grids of artists in different categories, with iTunes audio samples just a couple of taps away. Twitter #Music looks the part, but while you might find some diamonds in the rough, it won't necessarily be due to the app's calculations.

Draw Something 2 is exactly the kind of sequel we'd expect from a casual gaming juggernaut like Zynga: It's slickly refined, nicely expanded, and slathered with silly marketing tie-ins. Seriously, when will pop starlet Carly Rae Jepsen continue the game that it made us send "her" during the tutorial? All the same, this follow-up builds upon the sketch-guessing sensation by adding more social features and ways to interact, while wrapping everything up in a flashier package.
