There have been plenty of cool, new, innovative ideas that have hit the App Store that may not have existed if not thanks to the platform. Unfortunately, it's also shortened the lifespan of the puzzle genre by decades, thanks to every developer with an idea (read: how can we match 3 objects in new and exciting ways?) unleashing their derivative creation on the App Store. Sometimes the new ideas flail about miserably. Sometimes a game like Cash Cow comes along and is actually pretty fun with a unique gameplay concept."
