Now is the best time for web game developers to switch to developing mobile games, according to UBS Securities' latest survey.

A large number of web games started to be adapted into mobile games in the second half of last year, Liu Zhijing, director of China media and internet research at UBS Securities, said. Game developers should make full use of the next three years, which he considered the best time to make the transition.

The large number of mobile game players, which is steadily increasing, is the major reason for game developers switching focus. Meanwhile, web game developers are encouraged by Chinese mobile game players' greater willingness to pay, with 68 percent prepared to pay to play last year, compared to 28 percent in 2014.

Liu said that web game developers who are equipped with research and development skills, as well as resourceful distribution channels will eventually make a successful transformation into mobile games.
