The Main Advantages of HTML5 Slots

Products made in the described format have several key benefits:

  1. Excellent compatibility. All solutions can be launched in all browsers and operating systems without the need to download them. Owners of mobile devices, tablets, laptops, console terminals, and other equipment can play their favourite casino games. Users do not need to refresh the online casino page during the game session ― it is very convenient.
  2. Positive feedback from gamblers. They appreciate HTML5 devices for a high-quality picture, background sound, and the energy-saving mode. Users can view up-to-date statistics and the game history, share the results of their successful sessions on Facebook and Telegram pages, and participate in various tournaments ― all these options are available in HTML5 slots.
  3. Fast release with cost optimisation. The creation of HTML5 products does not require the purchase of additional software (plug-ins, frameworks), licence fees, and other costs. In practice, this reduces the development cost and also speeds up the release of devices. The world’s best studios produce 12–20 slots a year thanks to the described format.
  4. New features. For the first time, in HTML5 products, there are options for real-time multiplayer games, as well as an ability to spin the reels in different modes (standard, full-screen, double) and move to a specific part of the game without passing through all the rounds once again. Additional features always attract a new audience to the gaming site.
  5. Good prospects. Hundreds of specialists from Google, Apple, and other well-known companies are constantly working to improve the technology. Obviously, HTML5 will continue to offer new options for operators and casino visitors.

Technical Characteristics of the Solution

HTML5 games development: tech characteristics

The HTML5 programming environment includes an extensive list of tools, protocols, and languages.

Let us consider each component of the system in more detail:


HyperText Markup Language is used to:

  • put the initial data of the device in order (this includes the number of rounds, available prizes, and bonus sessions);
  • create the layout of the panel (the number of reels, cells, paylines, etc.);
  • describe the logic of the game (volatility, the RTP percentage, the formation of prize lines);
  • distribute hyperlinks to ready-made slot machines in popular search engines


A communication protocol that provides a long-term Internet connection between the server of the manufacturer or casino operator and the gambler's browser.

Having Websockets included in HTML5 makes it easy to:

  • develop solutions in the multiplayer mode;
  • organise tournaments


Cascading style sheets are responsible for:

  • the creation of a design of the gambling device, including the used colours, fonts, transitions, and the placement of elements on the page;
  • drawing the characters of slot machines;
  • creation of frame-based animation, as well as 2D and 3D elements of any level of complexity;
  • development and integration of mini-films (they help to better reveal the plot of the slot)

Local Storage

Browser data storage that allows you to:

  • link a social media profile to the slot machine;
  • quickly pass to a specific part of the game;
  • view statistics of rounds


The programming language is aimed for:

  • combining all structural elements of the game into a single mechanism;
  • imitation of the game scenes when basic parameters are changed (winning combination ― the launch of a bonus round, purchase of a special symbol ― increase in the RTP level);
  • audio programming (general soundtrack of the game and music screensavers when individual elements are activated);
  • compilations, updates, and processing of online slots in real-time
