So, bigger, more lucrative, more global, more competitive, and more complex are the phrases that describe the current mobile gaming ecosystem. The industry isn't just growing, however, it's also evolving something that can be clearly seen in the significant structural changes that are happening in markets such as Korea, Japan, and China. For example, over the past 12 months, we've seen two games - Puzzle & Dragons and Candy Crush Saga - each generate more than $1 billion in terms of mobile sales. It's the fifth year of our annual ranking and one that demonstrates the industry continues to grow quicker than anyone imagined.
