Each mobile device had its own special app or software for playing games until HTML5 became more popular. Some casinos did not provide apps for all of the devices, or had some difficulty getting around to them all. In addition to being compatible with a wide range of mobile devices, HTML5 has enabled casino operators to offer mobile gaming to a much wider range of players. The same software can be used by players using Apple iPhones, iPads, Android phones, and Windows phones to play mobile casino games.

Furthermore, HTML5 offers a greater variety of games to a wider audience at the same time, as well as improved graphics and animations, which has enhanced the experience of the game for the player. Aside from this, HTML5 software has afforded software providers greater scope to offer a broader range of games, so mobile offerings are now more diverse.
