What: Shares of Shanda Games (NASDAQ:GAME) have popped today by as much as 11% after the game maker launched a new title with early success.

So what: Shanda launched Million Arthur last night on Apple's iOS platform in China, and the company said it promptly rose the charts to become the No. 3 top grossing app across all categories within Apple's App Store in China. That climb occurred in less than eight hours.

Now what: The casual gaming market in China is growing quickly, and investors are optimistic about Shanda's new title getting such a warm reception. Shanda President Tunghai Chien said that Million Arthur grabbed more first-day daily active users in China than its combined total when it launched in Japan, Korea, and Taiwan. Separately, iPhone apps within the top 10 grossing spots have been estimated to generate at least $47,000 in revenue daily within the U.S. market. The figures are likely different for the Chinese market, but there's no doubting Million Arthur's strong showing out the gate.
