Today’s giveaway is one of the largest single game giveaways we have ever done, so tell your friends and family members because the odds of winning will be pretty decent.  AppAdvice has teamed up with Rogers George in order to offer you a chance at winning one of 14 promo codes for Nurikabe Vault ($3.99).

Nurikabe is a Japanese puzzle game from the creators of Sudoku.  In the game you must build a single wall by tapping on the open spaces in an attempt to divide the board into sections that are exactly the size the numbers on the board indicate.  The wall must be a single piece and never break, and none of the numbered sections may touch.  Each puzzle only has a single solution.

Nurikabe Vault features a collection of 500 puzzles of varying difficulty, a complete tutorial, optional hints, and OpenFeint integration so you can compare scores and challenge friends.  If you enjoy Sudoku, Nurikabe should be right up your alley.

To have a chance at winning one of 10 Nurikabe Vault promo codes, simply hit that green retweet bottom near the bottom of this page or retweet this post from your favorite Twitter app before 11:59 PM PDT tonight (January 30th). We will then search the Twitterverse for all of the retweets and randomly choose 10 lucky winners. The winners will be notified via Twitter, so please be sure to follow us so we can send you your promo code via a direct message.

Non-Twitter users and those of you who want to increase your odds of winning can simply leave a relevant comment below before 11:59 PM PDT tonight to have a chance at winning one of the other four Nurikabe Vault promo codes.

Feel free to participate in the giveaway via either or both methods. If you end up winning multiple promo codes, just give one away to a friend or co-worker. This giveaway is only open to U.S. iTunes account users.
