Welcome to another edition of Pocket Gamer's free game round-up - a feature that highlights the top App Store titles that have been made free in the past 24 hours.

As we've said plenty of times before, prices in the App Store change frequently. Go and grab these freebies before they shoot back up in price.

Remember: let us and your fellow readers know about any other great free apps in our comments section below.

And go here to find the latest App Store updates, price drops, and more.

Muffin Knight (Universal)

We've had some great limited-time free games pop up in the App Store over the last few weeks, but the Pocket Gamer Silver Award-winning Muffin Knight is definitely one of the best freebies of late.

Your aim in Muffin Knight is to retrieve and return a batch of magical muffins to an old fairy, who has laid a strange curse upon you: every muffin you touch changes you into a different creature.

Muffin Knight features Universal support, online multiplayer bouts, and Game Center leaderboards and achievements.

Epic War TD (iPhone and iPad)

Epic War TD is, as we're sure you've guessed, a graphically-rich tower defence title that pits you against 14 varieties of enemy over ten unique levels.

Game Center is on board with both leaderboards and achievements, but you can use OpenFeint if you're into that sort of thing.

Soul (Universal)

Soul is an adaptation of the popular Xbox Live Indie Game, which tests your dexterity and composure through a series of tricky mazes.

Your goal is to successfully navigate these awkward labyrinths and ferry a dead man's soul to heaven. You can attempt this feat over three difficulty modes.

We gave Soul a prestigious Pocket Gamer Silver Award at review.
