The game requires much teamwork and there were times he could not upgrade his customers' accounts in time, he says.

"When my luck is no good, I get paired with teammates. It's better to team up with people I know, those with good skills."

His services, in a way, feed on people's vanity and ego, says You.

"I've seen many people who pay tens of thousands of yuan to reach the highest level in the game, just so they can brag about it. Doing well in the game is a status symbol for them."

Many businesses have also been quick to bank on the trend and "mobile game zones" have sprouted in many cafes and other venues for players to gather.

Hea Cafe in Guangzhou is located on the second floor of Liri shopping mall. It opened in June and is packed every afternoon. Its employees have to borrow chairs from the mall and other shops for customers.

The cafe attracts the crowds because it provides internet connection speeds that are about five times faster than what people are able to use at home.

Furniture from Guangzhou-based company Eamast is also a draw. The company has been selling furniture customized for internet cafes for 14 years and it expanded its product range to include mobile gaming furniture in March. Tables, for example, are designed to be smaller and more ergonomic as there is no need for desktop computers.

The cafe also provides free gamepads, which can cost users 299 yuan ($45) each for high-quality play.

Cafe founder Miao Lin, 25, says the place was set up because of the game's popularity.

"It is entertaining and suits players' fast-paced lives. It's easier to learn compared with other games," says Miao. "It is also popular because it brings people together."

The game is a sign of the future of mobile gaming cafes such as hers. These online activities actually require "a space for people to enjoy playing mobile games together because of its huge fan base", Miao says. "The constant influx of new mobile games will also help extend the life of these cafes."
