How designers optimise websites for sites like mobile bingo

Sharing is caring!

Having a responsive website is absolutely essential these days, no matter what industry you’re in. After all, the majority of Google search queries are now made via mobile devices. So it makes perfect sense for the tech giant to prioritise responsive online platforms to the exclusion of all else.

This is especially important in iGaming verticals such as online bingo where most players prefer to gamble via tablet or mobile devices. To accommodate the hordes of phone-zombie gamblers, all of the best mobile bingo sites like Sailor Bingo, MrQ, and Buzz Bingo deliver flexible, fast-loading websites that make full use of the latest technologies. But it wasn’t always this way.

Early Bingo Websites

The first online bingo platforms were written in Adobe Flash – a powerful multimedia that boasted cross-browser functionality and could be used to handle animations, audio and video. As long as the end-user had installed the Flash plug-in, coders didn’t have to worry about their HTML being properly interpreted. But there were a few major drawbacks, especially in regards to smart-phones.

Not only was Flash buggy and unreliable, it was also a major performance hog and beset by sluggish loading times. These shortcomings certainly weren’t lost on Steve Jobs who in 2017 announced that Flash would no longer be supported by iOS devices. Citing some the above issues as well as a few additional problems relating to security, Jobs proposed an alternative. HTML5. 


Like Flash, HTML5 is compatible with all browsers. But it places less strain on CPUs and doesn’t require a plug-in. The framework is capable of handling video and audio which means that coders don’t have to rely on third-party programs. Instead, complicated tasks that required the installation of additional software can now be processed within mobile browsers. In addition, compatibility with touch technology has vastly improved since the introduction of HTML5. This is unsurprising given that Flash was originally intended for use with a mouse.  

How Designers Optimise for Mobile

So HTML5 has become an essential tool in the design of bingo and casino games. But what about the actual website? This is where Responsive Web Design and Progressive Advancement come in.  

The first method relates to the way developers craft websites to fit all device screens and orientations automatically. To achieve this, web designers use CSS media queries that enable them to create platforms to fit all manner of screen resolutions.  

Then you’ve got ‘progressive advancement’. This describes the practice of designing a website to operate on a bare-bones browser (like that of a mobile phone) first, before progressing to more advanced browsers such as the ones you might find on a tablet or desktop – many top developers often include more elaborate effects and interactions for larger screens to improve user experience – this is often left out for mobile devices because of the impact on page load speeds which are absolutely key to the mobile user experience.

Although mobile-first design continues to evolve, some of these techniques play a central role in the creation of flexible, highly-optimised gaming platforms – these are an absolute must for iGaming operators given current user trends.
