In all likelihood, the web-based online casinos that you are playing in right now uses either Flash or Shockwave technology to drive the game play. In previous years, Java was the predominant technology behind most web-based online casinos, although these have largely fallen out of use. Before then, HTML was quite popular and although it provided fairly fast performance, the rudimentary graphics quality led to it being replaced by the newer technologies. The newer version of web games today are similar to playing on mobile devices. It works a bit smoother on mobile but it is still a good gaming experience if you want the bigger screen to view the machines.
