AppAdvice has teamed up with 10tons in order to offer you a chance to win one of 10 promo codes for Azkend 2 HD: The World Beneath ($3.99) for iPhone, iPod touch, and iPad.

Azkend 2 HD: The World Beneath is the sequel to 10tons’ smash hit casual matching game. This time around you’re tasked with acquiring pieces of items that will help you find your way out of the bowels of the earth and return to civilization.

The game’s main story mode requires you to match at least three adjacent tiles with the same symbol in order to remove them from the board. This process will not only cause new tiles to appear, but also reveal more of the board. Once you have completed the board, a piece of the item you’re trying to construct will appear, and you’ll have to work it to the bottom of the screen in order to collect it. As you progress through the story mode, new and much more difficult challenges will be presented. To overcome these new obstacles, you’ll be able to earn and deploy almost 20 special power-ups.

Be quick, be smart.

The story mode consists of 60 levels, and includes eight hand drawn and animated scenes complete with professional voice acting.

Azkend 2 also includes a time mode and a medal mode. The time mode plays just as you would expect, requiring you to create matches and huge combos in order to climb the Game Center leaderboards. The medal mode actually consists of the same levels from the story mode, except this time around you’re trying to earn medals by accomplishing specific tasks.
