Xploding Boxes is an awesome puzzle game where you have to click (or touch) boxes which cause them to explode in four directions. You have a limited number of boxes you can explode, so make sure you choose wisely. Some boxes take more than one hit and the game gets increasingly difficult as you go through the levels. The first 25 levels are free, while the rest of the levels can be accessed by making an in-application payment.
Ebscer plans to release additional content and version 1.1 of Xploding Boxes will add levels 101-120 and will be released by the end of February. Remember, you must have App World 2.1 to make in-app payments.
