It's that time of the month again, when Pocket Gamer gives away a bounty of codes for last month's absolute best games to our wonderful community, the App Army.

For those unaware, that's our diehard band of mobile gaming enthusiasts. In exchange for their critical thoughts, we give them codes for unreleased games on a weekly basis and you can join in the fun by simply signing up on Facebook. That's a requirement to get a chance at a code in the giveaway, but more on that later.

This is a bonus round! Occasionally we get codes of games that didn't make it into our top games list, but we still feel deserve highlighting. That's exactly what happened here.

Warlock's Tower

Warlock's Tower is a retro-inspired puzzler that poses a fair challenge. You have to navigate a bunch of obstacle-filled rooms which should be difficult enough. But no, in Warlock's Tower you lose a life each time you move.

You can play with a friend in tag-team as you strive to deliver a letter to the resident warlock, avoiding zombies, flying eyes, and slimes.

At review, we gave Warlock's Tower a Silver Award and said: "Warlock's Tower offers satisfying puzzles crafted from a strong central mechanic and smart level design".

Okay, I'll give it a go

Not so fast! First you have to sign up to the App Army here, then write your name as it appears on Facebook in the comments beneath this post. We'll then select the lucky winners over the next few days.

We have iOS and Android codes for this one, so please specify which platform you'd prefer your code for when you request.

And that's it. We'll be back tomorrow with a brand new game so keep checking back at 5PM GMT.

What's the App Army? The App Army is Pocket Gamer's very own community of mobile game experts. Each week, we provide them with a bunch of free codes and early access to the hottest upcoming games so they can provide their thoughts in features like this. We also host regular community-driven events with them in mind like tournaments, giveaways, and multiplayer evenings. To join, simply follow this link to the page on Facebook.
