No-Download & Instant Play

Instant-play gaming means the software allows you to play right there in your browser without the need to download and install any additional programs. You simply click the online casino game you wish to play and your sessions start within seconds.

Mobile Casino Software

Real money mobile casino software is just as, if not more, important than desktop and laptop software. Our recommended casinos highlighted at the top of this page also partner with mobile software providers so that each game is also playable on any smart device operating system.

Downloaded Software

While most casino sites have embraced the no-download, instant-play software, some still require a download element. This process is very common in online poker as each online casino promotes a downloadable online poker client to enjoy a richer gaming experience.

How We Rate Online Casino Software Providers

Dozens of notable software providers operate in the online gaming industry. While some are names players often encounter, some are newer design houses that might not be familiar to you. Beyond a company’s history and reputation, here are the factors we consider when reviewing software companies.

  • Gambling License: The software provider should have their RNG software tested by third-party auditors, including government licensing agencies.
  • Graphics and Gameplay: Game graphics should be entertaining and pleasant, while the gameplay should be fast and smooth.
  • Updates and New Releases: The best software providers have new releases each month. Software companies should be on the cutting edge of game design.
  • Game Selection: The provider should have a wide variety of jackpot sizes, game features, sounds, graphics, and themes.
  • Mobile Optimization: It’s best if 100% of the desktop games are converted for Android and iOS. If not, the provider should have hundreds of mobile casino games.
  • New Trends and Technology: The company should keep up with the latest trends while adapting to new technology. Live dealer games and HTML5 technology are two examples.
  • Award-Winning Software: Players and industry organizations alike should recognize a design house for its accomplishments and innovations.
