It's day 17 of Pocket Gamer's 2019 advent calendar giveaway. For those of you who haven't been paying attention over the last few weeks, the advent calendar is a chance for you to win codes for some of the biggest and best games of the last 12 months.

Today we've got 5 iOS codes to give away for the excellent Snakebird Primer. Unfortunately we don't have Android codes for this one, but fret not Google gamers, because we'll have some goodies for you in the next few days.

What's Snakebird Primer? Well it's a puzzler that sees you stretching birds out to reach the exit. It's brightly coloured, but don't let that fool you. This is a super challenging game that eases you in and then amps up the challenge to the very best hair-pulling levels. You can read what our App Army thought of the game by clicking here, or check out the trailer we've embedded below.
