AppAdvice has once again teamed up with Megatouch in order to offer you a chance to win one of five promo codes for the recently reviewed Nerdy Birds Social HD ($0.99) for iPad.

In Nerdy Birds Social HD, your job is to rule the roost by creating the most and the highest scoring words from a set of eight letters. Don’t think you can hack it? What are you, chicken?

During each 90-second round you’ll be given a set of brand spankin’ new letters to try to create words from. To create words, just tap on the letters and then hit the big green “Enter” button. If it’s a valid word consisting of three or more letters, you’ll see it placed on the list above and your score will be recorded. If it isn’t, your letters will simply be reset. Don’t worry, you won’t incur any type of penalty for entering invalid or already created words.

Rule the roost.

Keep in mind that when creating words, you can’t use the same letter twice. You can, however, get a new set of letters once during a game, and you can shuffle the letters to try and jog your brain. The game includes special bonuses for not only finding the top-three highest value words from your letter set, but also for discovering the mystery word in each round.

Nerdy Birds Social HD includes a single-player mode, a split screen multiplayer mode, and an online multiplayer mode via Game Center. Both multiplayer modes play the same, where you compete head-to-head against your opponent in real-time trying to obtain the highest score. You’ll have to be quick if you want to win since you can’t use any of the words your opponent has already played.
