Offering popular Game Closure games such as Battle Cats Galaxy (pictured main) and Fishing Star QUICK, the LINE QUICK GAME platform allows users to play with their friends without downloading or installing any additional applications.

LINE QUICK GAME adds to an exploding HTML5 gaming market worldwide with more than 75 million monthly active users on LINE’s messaging app in markets such as Japan, Taiwan, and Thailand.

In the past year, HTML5 mobile gaming has been propelled by a series of next-generation platforms embedded directly within messenger applications such as the widely popular Facebook Instant Games and WeChat Mini Games, facilitating easy and instant gameplay among friends and cultivating social and seamless gaming experiences.

The immense potential of the instant games market has attracted the top HTML5 gaming companies worldwide including Game Closure.
