This category is about the browser-based game.
Many games these days avoid the hassle of downloading the game and then installing it. They make the game browser-based, so that the user can directly play the game without any prerequisite.
Sometimes users get disconnected with the internet in middle of the game because of which they may loose the game.
Provide offline support for game, so that people can save their game to home screen, and play offline.
Consider a browser-based 2048 game, having offline support will help the users in continuing the game.
