What is HTML5?

So what exactly is HTML5? HTML stands for HyperText Markup Language, and 5 is the latest version of the language. It's a code used for web pages, and is made up of three elements: HTML, Cascading Style Sheets (CSS) and JavaScript.

HTML5 was designed for any online function, without the need to add browser plug-ins. It can handle anything from music to animation, and has two big advantages for online casinos and games developers. Firstly, it isn't proprietary, which means you don't have to pay royalties in order to use it. Secondly, it is cross-platform and so works on any device, whether you are playing online casino via smart-phone, tablet, notebook or Smart TV.

Before HTML5

To understand the impact of HTML 5 casinos, it is important to remember how pre-HTML 5 casinos worked, particularly for mobile users. Kiwi casino players who like to play on the move, tend to visit their preferred online casinos using a mobile browser. Every kind of mobile device needed its own app or downloadable software to play casino titles. This could be fiddly and inconvenient and made for a frustrating and confusing experience for online casino game players, particularly as not every New Zealand casino offered apps for every mobile device on the market.

Mobile online gamers who had Apple technology had it particularly tough as it was difficult to find New Zealand online casinos that worked with their devices. Apple did not allow Flash to run on its iOS system, but as most online casinos relied on Flash, this meant that Apple-technology users were unable to access the best New Zealand online casinos.

Benefits of HTML5 for Online casino games

HTML5 casino games have various benefits that they offer gamblers. In this section, we will cover some of the advantages players enjoy when they play casino games on HTML5 casinos.

Cross Platform Support

The nature of HTML technology enables players to play casino games from various mobile browsers (Chrome, Safari, and Firefox), devices, and platforms. HTML allows developers to create cost-saving games that can work on various platforms. The development of these games allows casino game companies to create titles that run on any internet-connected devices with a browser anywhere in the world. Games built using HTML 5 can fit any screen size, have an extensive web graphics library (2D and 3D) for game files, have audio and storage API, and are compatible with any platform after the game's code is written.

Resources and Adaptability

HTML5 has no platform dependency because it is supported by various web browsers including Chrome and Firefox. Therefore, it has large set of libraries containing resources that support HTML games. These resources reduce the complexities faced when developing casino games and make them easier to market.

Strong Technology

HTML5 is a web internet standard with reliable and trusted frameworks. Canvas and Web GL are two of the prominent technologies used in the development of HTML games. They help casino gaming companies develop interactive games that work on cross platform. These technologies also form the code base that powers HTML games and create a wonderful playing experience.

Marketing and Promotions

Promoting HTML games is a business strategy that allows casinos to get more players to their games. Game developers can create smart promotional strategies that emphasize the visuals, graphics, animations, and other features of their game. Also, the cross platform nature of HTML5 casino games makes it easier for word-of-mouth marketing because the barrier to entry is low. The ease of promoting these games further reduces the money spent on development.


The games are easily accessible because they can be played from any browser, tablet, mobile phone, or device with an internet connection. HTML games are also known for their low bet limits which means that players have to spend little money to play these games. These games also store user data using cache manifest technology which makes it easy for players to restart or begin new gaming sessions seamlessly.

The impact of HTML 5 casinos

HTML 5 has impacted casinos in many ways including:

  • The arrival of HTML 5 led to a revolution in the experience of New Zealand casino gamers. For a start, the use of HTML 5 as the building block for casino sites and games enabled those with Apple devices to enjoy online casino gaming with their iPhones and iPads. This is because HTML5 works well with the iOS operating system used on Apple devices, which was great news for Apple users throughout New Zealand.
  • It was also a positive development for New Zealand casino site operators, because iOS-based products are popular throughout the country, particularly among mobile device users. By being able to access technology that functions with iOS devices, casinos have been able to serve a much bigger audience, and New Zealand casino users have been switching in large numbers to HTML5 casinos as the technology became more common.
  • And since HTML 5 also works on non-iOS operating systems, casino sites and game producers were able to offer a full range of games to all players, and were no longer required to provide a variety of different apps. Although you may still come across some New Zealand casino sites that use Flash technology, HTML 5 has grown rapidly in popularity and is on the way to becoming the technology of choice for Kiwi gamers and online casinos.

Games that are produced for HTML 5 can offer a better quality of graphics and much more immersive gameplay. Slots titles at HTML 5 casinos are usually among the latest and most impressive in the industry and provide the most exciting experience.

HTML5 technology has also made it possible for game developers and online casinos to offer a much wider range of online games to the New Zealand player. You can play everything from the latest video slots to high-definition video poker and classic table games such as roulette and blackjack. All these HTML5 games offer enhanced graphics and more interactive possibilities such as live dealer games, which are increasingly popular.
