Pocket Gamer's best games of September giveaway - The Witness

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 Witness is the latest puzzler by Jonathon Blow, who arguably kicked off the indie sensation with Braid almost a decade ago.

It took a full eight years for his follow-up, The Witness, to arrive - and boy was it worth the wait. It's a gorgeous adventure strewn with puzzles to crack.

At review, we gave it a Gold Award and described it as "A game that doesn't hold your hand, but gives you an intriguing world to explore on your own"

Not so fast! First you have to sign up to the App Army here, then fill in the super quick Google Form below.

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