The simple free iOS game Zippy Zone is our Game of the Day. This simple, but extremely addicting game is one of my newest and hottest games on the App Store. It has one of the simplest gameplays. Your screen is divided in black and white, and you need to swipe and move the black creatures to the black side, and the white creatures to the white side so they disapear.
After you make all creatures invisible you pass the level and there are 50 levels, for now. Logically, as you progress the levels get more challenging and harder. Zippy Zone is very entertaining and it is another proof that you can create interesting and addicting games, if you are creative. It is trending right now and I think it will be huge success. Try it, it is available for devices with iOS 5.1.1 and it is optimized for iPhone 5.
