In this Pocket Gamer Gold Award-winning tower defence title, you're tasked with protecting a fantasy kingdom from waves of orcs, trolls, and other nasty beasties.
You do this with a variety of customisable towers, as well as a team of hardened hand-to-hand units that include powerful elven warriors.
At review, we said that Kingdom Rush "breathes new life into the tower defence genre, and has a whole lot of laughs doing it".
You'd be a fool not to download it while it's free, in other words.
Spirit is an interesting retro-inspired iPhone and iPad title in which you take control of a wandering life force.
Your aim is to protect this force against waves of procedurally generated enemies by distorting space and forcing them into another dimension.
The Android version of Spirit nabbed a more-than-respectable Bronze Award at review.
Download both games now, and be sure to grab the best free apps every day via the Free App Alliance app.
