When it comes to the online gambling world, technological advancements have made some huge changes to the industry. This makes sense, as it was technological advancements that gave birth to the iGaming industry.The likes of mobile gaming have been developed as a result of new technologies, and virtual reality gaming has now joined the market, in one of the most highly anticipated advancements.However, one of the most important changes recently has happened with far less fanfare, and that is the switch that most developers have made to HTML5.The Finer Details Of The Move To HTML5 Casino Games

What exactly happened?

For a long time, most online games operated on Adobe Flash software, a multimedia platform add-on.Flash can be used by programmers for video, audio, animations, games, and more, and it became hugely important to the iGaming world.This was fine for a fair few years, but once games started to evolve and grow, using Flash became troublesome, essentially the iGaming industry evolved past the limitations of Flash, as did many others, as proven by Steve Jobs now famous “Thoughts on Flash” piece, which stated the technology was now obsolete.As a result, since early 2014, the switch has been taking place to HTML5.

What is HTML5?

HTML5 is the latest Hypertext Markup Language (HTML), it is used mainly to create webpages. The technology had been spoke about for some time, and was eventually launched in 2014 with many features that mirror Flash, but instead of an add-on, HTML5 is a core component for creating web content.The switch means that battery life on devices is improved while playing online casino games, and the removal of the add-on part of the technology also leaves you less vulnerable to security risks, something that is, obviously, of the highest importance to online gambling fans,
