Feb 17, 2011 - AB Dev today introduces Shark Logic 1.0, their new brain-teasing puzzle game for Apple iPhone, iPod touch and iPad. In Shark Logic, the goal is to eat all other fish on screen to complete the level. But it's not so easy! Your shark can swim only up, down, left or right, and it cannot be stopped until it eats something. Shark Logic features over 30,000 unique levels, Game Center enabled as well as great sound and music.
