According to the report by Eguan, the scale of Chinese mobile game market exceeded 1.2 billion RMB(190 million USD) as of Q1,2012.
Its revenue increased 10.0% compared to previous period.
And the number of mobile game users reached 189 million people as the same time.
Its number increased 16.5% compared to previous period, and this number is expected to exceed 200 million people on Q2.
Though Eguan also said Chinese mobile game market continue to growth in future, it maybe the truth. That's why there are 1 billion mobile users in China, and the number of this report was only its 20% :)
