SEGA is on a roll right now. The company has been blasting the App Store with huge price drops on many of its Sonic titles over the past few months. The popular monster-collecting gambling game Dragon Coins hit iOS in May. A few months ago, SEGA launched Super Monkey Ball Bounce in Canada (still not available in the U.S.). Today, Sonic will make an appearance in another jumping game with Sonic Jump Fever, available in the App Store now.
