AppAdvice has teamed up with Infinite Dreams, our latest AppAdvice Daily podcast sponsor, in order to offer you a chance to win one of five promo codes for Jelly Defense for iPhone, iPod touch, and iPad.

Jelly Nation used to be a land full of peaceful, fun-loving creatures until mysterious invaders showed up and started ruining the place. Now it’s up to you to help stop them from completely taking over by joining the resistance and sending them back to whatever awful place they came from!

Stop the invaders!

Invaders will march down set paths towards precious gems, and it’s up to you to strategically place jelly towers along the path in order to cut them down where they stand. Invaders come in different sizes, forms, and colors, so you must try to use your towers’ abilities against their weaknesses.

For example, you can place a universal tower (dual-colored) on the path to ensure that everything that passes by gets targeted, but by placing a single-colored tower you can actually get a leg-up on your competition since they are more powerful against enemies of the same color. Of course, the problem is that if your tower doesn’t match the current color of your attackers, it will be rendered useless.

Building new towers is as simple as dragging them from the bottom of the screen to a spot on the map, that is, as long as you have enough coins available to build them. You can gain additional coins by tapping on the ones dropped from fallen enemies. And, like most tower defense games, Jelly Defense allows you to sell towers to quickly gain back coins, which can be used to upgrade already standing towers as well.

Jelly Defense includes 22 campaign missions, eight power-ups, 10 towers, two levels of difficulty, and Game Center integration. You can pick it up for the introductory price of $.99 and start playing immediately, or you can try to win yourself a copy directly below.
