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. Let's kick things off.

The House of Da Vinci

The House of Da Vinci is a puzzler cut from the same cloth as The Room franchise. You'll explore a beautiful 3D location solving puzzles.

You play as Da Vinci's apprentice who is investigating his master's disappearance. You head straight to his workshop to look for clues.

At review, we gave it a Silver Award and said: "The House of Da Vinci may borrow heavily from The Room, but it's a well-made, detailed, and complex puzzler with a lot to offer".

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.

This is only out on iOS, so we don't have Android codes for this one. We'll be back tomorrow with more though so keep checking back!

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