Best Flash No Download Casinos

OUSC ApprovedThough many experts have predicted that Abode Flash is going to be replaced, the most common instant-play casino technology is still the Flash game. Flash is a free software maintained by Adobe Microsystems. It supports animations and high-quality video streams, making it perfect for casino games.

Most web browsers still enable Flash by default, though Google Chrome users might need to download Adobe Flash. Some of the top software developers support Flash, even if they use other technology for no-download games. Microgaming, NetEnt, RTG, and Playtech all use the Flash casino instant play option.

Top Flash Instant Play US Online Casinos

Below are a couple of our gold-level sites which use instant-play Flash games. If you have crashes in Flash, it’s probably because your computer and your browser each have a version which are causing troubles, so you need to deactivate one of them.

Best HTML5 No Download Casinos

HTML5 was chosen by the Worldwide Web Consortium as the handpicked successor to Flash and Java. The technology breaks down the barrier between devices and browsers, so it might one day make mobile apps obsolete. HTML5 has higher quality streaming and faster real-time gameplay, so streaming live dealer games is better with HTML5.

This software allows no-download casinos to operate seamlessly with Android and IOS smartphones and tablet computers. HTML5 is the first mainstream programming language to be designed to support mobile gambling and social games. This second factor might not matter much in the online gambling industry, but it should help HTML5 become the dominant no-download gaming platform of the future.

Best Java Instant Play Casinos

JavaScript is an open-source programming language used to create browser-based games. Java is a platform supported by the Oracle Corporation of Santa Clara, California. Java provides its users with cross-platform access, so JavaScript which was written to power online casino no download games for a PC works just as well on a Java-enabled smartphone.

Instant-play Java games are not as common in the online gambling industry as they once were. Oracle has announced it is going to stop supporting Java plugins after Java 9. While it works with all types of online casino games, Java is generally slower than Flash or HTML5 games.

Types of No Download Casinos

Players encounter one of three types of instant play casino software: Adobe Flash, Java, and HTML5. The first two are the most common options, while the third is still in development and therefore rarer. Occasionally, tech publications suggest Adobe might stop supporting Flash, which would mean Java gaming would become much more popular.

Unfortunately, Oracle appears as if it might not support the traditional Java applet much longer, either. Adobe Systems continues to support Adobe Flash at the moment, but its ascendancy won’t last.

In the coming years, you can expect to see HTML5 become the dominant way to play no-download games instantly. HTML5 not only provides better graphics and faster streaming, but it breaks down the barriers between platforms. If you download HTML5 video streaming software, the same software will work on smartphones, tablets, personal computers, or laptops. This means developers only have to design one software package, which makes it cheaper and easier for them.

Adobe Flash Instant Casinos & Games

Flash Playerflashicon is a free software application supported by Adobe Systems Incorporated of San Jose, California. Adobe did not develop Flash but inherited the software when Adobe bought Macromedia in 2005. Flash, a free downloadable software, dominates on the instant play online casino market.

Most online instant play casinos use Flash games. Designers love to write games for the software, for the many reasons listed above. If you see links for “Flash Casino” or “Flash Games”, you’ll need an Adobe Flash software download to play the game. Adobe Flash comes automatically these days on most browsers. When you update to the latest version of Google Chrome, Mozilla Firefox, Opera, or Safari, you’re likely to have Flash Player downloaded to your computer automatically.

Do you need help enabling Flash Player on your browser? Check out OUSC’s easy Flash Player How-To Guide for Chrome and Safari.

  • Supports animations and high-quality video streams.
  • Used by top providers like Microgaming, Playtech, and Vegas Technology.
  • Adobe Flash is free to download.
  • Easy manipulation of 3D images.
  • Creates textured meshes in 3D space.
  • Reorients and restyles texts to create solid topography.
  • Supports dynamic audio mixing for real-time music.
  • Efficient use of hardware to accelerate the manipulation of bitmaps.

Drawbacks
  • Frequent crashes of browsers.
  • Adobe might not support Flash Player in two years.

Complaints about Adobe Flash Crashes

adobe crash

Typical warning screen for Flash player

Both Chrome users and Firefox users complain that Adobe Flash crashes their browser often, even when they have the latest version.  This makes gaming difficult, especially when someone is gaming for real money.

Those crashes eventually are going to kill Adobe Flash. Encoding.com reported that only 4% of mobile and web videos watched in 2015 were watched with Adobe Flash. That percentage was down from 21% of the video market in 2014. In one short year, millions of viewers abandoned Flash Player.

For that reason, Encoding.com said it expects Flash to disappear entirely from its report in the following years. On mobile devices, the 13-year old H.264 seems to be the momentary video software of choice. HTML5 options like WebM and H.265 are the current trendy predictions for the software tech analysts believe will replace Flash.

By December 2020, Google will remove Flash support entirely-aligning with the already announced plans of Microsoft, Apple and Firefox developer Mozilla.

Which Online Casinos Offer No Download Flash Games?

Hundreds of different websites offer Flash games. Despite the dire predictions, an online gambler who clicks on an instant play game is likely to need Flash Player. Here is a partial list of top sites which offer Flash games:

  • Vegas Slot
  • All Slots
  • 7 Sultans
  • Mr. Green
  • Mummy’s Gold
  • Cabaret Club
  • Platinum Play
  • All Jackpots
  • Ruby Fortune Casino

The list could go on and on, but that should give readers an idea of the many options available. Flash casinos are by far the most common way to gamble online without using the downloadable casino software. Other options exist, so let’s take a look at those.

Java Instant Casinos & Games

javascriptJava is a computer programming language, but it is also a web community of programmers. The community numbers more than 9,000,000 programmers, who developer plugins and other application for the Java language. Developers use the language so often because it has cross-platform benefits. Browser-based games written in JavaScript tend to be slower than Flash games, which is a major reason Java Games are not as popular as Flash games.

Java was designed as a concurrent, object-oriented, class-based code which lets application developers write open-ended applications. Java was first marketed using the slogan, “Write once, run anywhere” (WORA). That term still describes the benefits JavaScript offers pretty well. Java was acquired by Oracle from Sun Microsystems in 2009-10. Oracle describes himself as a “steward of Java technology, with a relentless commitment to fostering a community of participation and transparency.”

Like Flash, a download is needed to make your computer compatible with Java games. Players can go to the official Java website to download the Java virtual machine. Once downloaded to your computer, the Java plugin interfaces with instant play online games to provide a browser-based gaming experience.

Thumbs Up
Benefits
  • Cross-platform access. If JavaScript is written for a PC, it works on a Java-enabled smartphone, too.
  • Downloading a Java machine is quick and free.
  • One of the most popular programming languages.
  • Supported by Oracle, a $100 billion corporation based out of Santa Clara, California.
Thumbs Down
Drawbacks
  • Requires the download of a Java virtual machine.
  • Not standard with most browsers like Flash, so you need to actively download the software.
  • Oracle plans to end its support of Java plugins after Java 9, which is about to release.
  • Security concerns, which is why browsers stopped supporting plugins in general.
  • Slower than browser games which use Flash or HTML5

Oracle Is Ending Its Support of Java Plugins

Readers might be surprised to learn that Oracle is planning to end its support of Java plugins in the near future. Oracle plans to deprecate its plugin in its release of Java 9. At present, a beta version of Java 9 is in circulation. The move was forced on Oracle by the web browsers. Chrome deprecated browser plugins in April 2015. Firefox announced plans to do the same thing in October 2015. Microsoft’s Edge browser has lacked plugins for a while.

Only Internet Explorer 11 still supports plugins. Oracle recently released suggestions for organizations who want to migrate away from the Java plugin, so the way Java games work at online casinos is likely to change in the next year or two. For gamblers wondering where that leaves them, Oracle’s suggested option is migrating to the plugin-free Java Web Start technology.

Which Online Casinos Use Instant Play Java Games?

While Java games are not as common as Flash games, it is the choice of many top online casino operators. The list of brand name instant play casinos that use Java includes

  • Paddy Power Casino
  • Bwin. Party
  • Betfred
  • Grand Parker
  • Loco Panda
  • Win Palace Casino

As you see, the two dominant ways to play instant games are likely to be discarded by the companies which support them at present. People might be wondering which options they’ll have for no-download gaming in the future. The answer is HTML5 games.

HTML5 Instant Play Casinos & Games

html5HTML5 is a markup language which was published by the Worldwide Web Consortium (W3C) in October 2014. HTML5 is a long-awaited update of the HTML language. HTML 4.0 was released in 1998, which is eons ago in the software development field. Development on HTML5 began way back in 2004, back before technologies it is designed to enhance (smartphones, tablets) were on the market.

The long time to develop and publish the language is likely the result of the revolutionary changes in telecommunications over the past 12 years. Likely, coders had to restart their work on HTML5 on one or two occasions.

Thumbs Up
Benefits
  • Breaks down the barrier between devices and browsers. HTML5 could and should make mobile apps obsolete.
  • Higher quality streaming and faster real-time gameplay for live dealer games.
  • HTML5 games make mobile casinos more compatible and accessible.
  • Markup language can be read by average people, but also the devices.
  • Designed to support smartphones and tablet computers.
  • Will make social gaming easier. This is an added bonus for gamblers because it should assure the dominance of HTML5.
  • Supported by the Worldwide Web Consortium (W3C), which maintains international standards on the Internet.
Thumbs Down
Drawbacks
  • Not used by many online casino companies yet.
  • It’s unknown which HTML5 multimedia application will become the dominant one.

World Wide Web Consortium

World Wide Web ConsortiumHTML5 saw its first significant impact back in 2015. Given the fact it had been published only a few months prior, that impact was immediate and stark. The Worldwide Web Consortium is a 408-member group based on the campus of the Massachusetts Institute of Technology (MIT) in Boston.

W3C maintains online standards for the entire Internet. Members of the consortium include Google, Facebook, Twitter, IBM, Microsoft, Mozilla, Netflix, and PayPal. Japanese corporations like Sony and Hitachi are members, while Chinese corporations like China Unicom and China Mobile are also members. Public institutions also are consortium members, such as the Library of Congress, The National Archives, MIT, the Open University, the German Research Center for Artificial Intelligence, Zhejiang University, the Chinese Academy of Sciences, and Nanjing University.

All of this is to say that any online technology published by the W3C is likely to be quite successful. Gamblers should expect to see no download casinos and games change over to HTML5 formats in the next few years. Mobile gaming certainly is going to change–and probably sooner rather than later.

WebM: An Example of HTML5 Video Streaming

WebM is an example of what is possible with the HTML5 language. WebM became the top video file format for HTML5 after its release in May 2015. The format is sponsored by Google. Because Google owns YouTube, the world’s biggest video site offers WebM videos as part of its HTML5 player and plans to encode the entire YouTube portfolio to WebM. Nintendo Wii, Skype, Wikimedia, and 4Chan all support the video file format already. Others are likely to follow.

As you can see from the bullet points listed above, the advantages of HTML5 are many. People have been predicting the markup language’s coming dominance for a long time. Before he died, Steve Jobs said it would surpass Flash. Microgaming began experimenting with HTML5 back in 2012, though it was rolling out the Adobe Air mobile casino software at the same time. Since then, more industry experts have added their voice to the growing consensus that HTML5 will eventually overtake its rivals and change no-download online casino games.

How HTML5 Improves Instant Play Online Games

In fact, HTML5 is such a powerful tool that it is likely to make mobile casino applications altogether obsolete. The language is going to improve mobile games, live streaming, and cinematic slots. Interactive gaming is set for a revolution. Developers are going to be able to design sharper images and produce more fluid graphics.

The real progress is the ability of HTML5 to natively support video, while simultaneously working across all platforms. The cross-platform adaptability makes HTML5 a far superior tool for developers because they won’t have to design separate software for the online and mobile versions of a game. Software development executives are going to see that they can get better products with half of the investment in time and money. If nothing else did, that alone ensures HTML5 is going to dominate the Internet gaming operations of the future.

Which Online Casinos Use HTML5?

At the moment, though, few of the leading online casino operators use HTML5. Nearly four years after Microgaming said they were going to migrate to their mobile games to this technology, they still use Adobe Flash games to support the bulk of their no-download games. That is likely to change over the next years.

HMTL5 is being used by most top mobile gaming software companies already. As for traditional online casinos, Microgaming has versions of roulette, blackjack, and their most popular slots which use HTML5. For instance, an HTML5 version of Tomb Raider Slots exists. People who want to test one of these games should take a look at the instant play Tomb Raider.

What Are No Download Casinos?

No Download iconInstant play casinos allow online players to visit a casino site through their web browser and start playing immediately, without having to download the casino software. These types of casinos offer greater privacy and are a great option if you don’t want casino’s software on your desktop.

If you travel, you might not want someone in a hotel lobby or airport terminal getting quick access to your casino account. No-download casino gaming adds more privacy, which makes it harder for people to quickly access your site settings.

Graphics and Sound Quality

Recommended iconThe sound quality and graphics in instant play online casino games are on a par with downloadable games now. Technology has caught up with the design skills of game developers.

In most cases, casino software uses the same sound effects, music, graphics, and animations which are used in no download games. Thanks to the Flash and HTML5 platforms, no-download video slots are every bit as advanced as the fully downloaded online slots.

Mac and Linux Compatibility

Desktop iconMac computers use Flash and HTML5 software to load the casino instant-play games in the web browser. This circumvents the need for software downloads which are not compatible with Mac computers.

Even today, many developers still do not design online casino software which is compatible with Mac, because they focus on the 95% of the gambling community which uses Microsoft Windows computers. Instant play casinos, therefore, are the only option for players who use Mac operating systems.

The same can be said of Linux instant-play casinos. Linux gamblers prefer less expensive solutions, often with computers, they build from component parts. While Windows compatibility software exists, this basically turns their computers into a Microsoft product.

Game Selection

Game Selection iconAt one time, the game selection in an instant casino were 25% to 50% of the total downloadable gaming content. Due to the latest advances, instant casinos’ no-download inventory contains every game the downloaded software does. In fact, many operators have gone to instant-play gaming altogether, with no option for a download.

All major games are available for either the no-download casino or the downloadable software. Whether a gambler wants to play online slot games, video poker, or table games, that gambler has the choice between browser-based or download-based games. Simply choose the gambling method you prefer.

Security Issues

Safety iconWhile online casino operators take measures like SSL certificates to assure payments are secure, the security issues are not greater in the gambling industry than other e-commerce. In fact, online casinos do not save credit card information or banking information — only names and addresses. For that reason, online casinos are not a major target of identity thieves and other scam artists.

The same applies to the average no download online casino. Banking institutions are hacked more often than Internet casinos because there is more profit to be made launching cyber-attacks on financial institutions. While anyone can be hacked and it’s important to report on the security procedures used by no-download casinos, cyber-attacks can happen to any online website you use.

More Instant Play Casino Information

In the discussions above, I noted the type of software which several top companies use. It would have been unwieldy to name all of the companies in those topics, so I wanted to include information on several other top online casino brands in the space here. In doing so, I discuss providers like NetEnt and individual operators like Bovada.

I’ll also offer the briefest of information on mobile casino apps. While that information is not specifically part of our discussion of no download casinos and games, the inception of cross-platform programming language means the boundaries between mobile and online casino gaming are being torn down. Separate discussions of online and mobile software won’t always be the case.

NetEnt Instant Play Casino Software

Net EntertainmentNet Entertainment, the Swedish software designer often called “NetEnt”, is a leader in both the instant play casinos and mobile gaming niche. NetEnt has to be on the cutting edge because they’re a leader in the 3D slots category. Since 3D gaming requires the best graphics, Net Entertainment is developing both HTML5 and JavaScript games at the moment.

Their in-house software package is called “Game Framework”, which includes Scrum teams for all three types of code. For those who think they might enjoy designing casino software, developers need to experience in an Agile/Scrum development environment, proficiency in English, and a willingness to live in Stockholm, Sweden.

Net Entertainment also happens to be a leader in “direct play” mini-games, which are browser games offered for quick-play while a player waits for other programs to start. Mini-games are popular with online sportsbooks and sports exchanges, which sometimes have delays while events play out. A mini-game allows someone to make in-play sports bets on live sporting events in their browser’s window while playing mini-blackjack, mini-roulette, or mini-slots in another tab.

What Is CSS3?

css3People reading the NetEnt write-up might be wondering what CSS3 is. CSS3 is the latest version of “cascading style sheets”, a style sheet language used for describing the presentation of a markup language. Like its predecessors, CSS3 is a cornerstone technology for websites to create visually engaging web pages. The technology also helps create useful interfaces for mobile applications and web applications. CSS3 can be used to design games.

Most browsers implement the latest version of CSS standards like they do with HTML, but CSS3 is not a popular choice in the online casino industry. Developers have written games using the style sheet language, but programmers indicate it is frustrating to use because the games freeze. While NetEnt wants designers with experience in that field, it does not imply a fourth major option for instant play games, though it supports markup language like HTML. For instance, HTML+CSS is a popular choice for creating animated pictures.

Bovada Instant Play

Bovada Casino logo sm

Bovada is an example of a US online casino which uses instant play casino games exclusively. Many Bovada no download mobile slots now use HTML5 technology, though some of its mobile slots are designed for Flash Player. Bovada, which is the US-facing successor to Bodog, uses a variety of software packages to support their online casino, mobile casino, and their sportsbook.

The main software providers are RealTime Gaming (RTG) and Rival Gaming. RTG began developing HTML5 mobile slots in early 2015, so it should be a matter of time before all of Bovada’s online slots are converted to HTML5 games.

The Bovada website offers advice for instant play on their site. Most of the tips involve mobile gaming. Bovada notes that Flash games do not interface well with Apple products unless a “special browser or plug-in” is used. Plugins are being phased out in general, which could make it difficult for Mac users on Bovada.

Bovada recommends that players find sites which use HMTL5, then notes that they intend on becoming one of those instant-play online casinos. Because it offers a $3,000 welcome bonus and over 250 casino games, OnlineUnitedStatesCasinos recommends U.S. players looking for no download games should try Bovada first.

Blackberry Instant Play Mobile Games

blackberryAll mobile casinos offer downloadable apps for Apple iOS and Android phone. Some mobile casinos offer Blackberry and Windows Phone apps, while others do not. The bad news for Blackberry users is that many sites do not offer downloadable software for their mobile gaming. The good news is that Flash is supported on Blackberry phones, so gamblers who use Blackberries should be able to play all mobile table games and most mobile slots.

Windows Phone Mobile Games

windows phone Windows Phone smartphones are not supported by many mobile casinos. Like Blackberry, you’ll have to use Flash games, JavaScript, or HTML5 to play in the browser. Luckily, Windows Phone supports Flash, so most mobile casinos should be accessible for Windows Phone users.

Whichever mobile operating systems you smartphone uses, I suggest you make certain the device is optimized for HTML5 video streaming. No download casino games are undergoing a revolution. While Flash games are the dominant factor right now, it soon won’t be the case anymore.

Should You Play at Instant Play Online Casinos?

For those players that do not want to download casino software, instant play casinos offer you many benefits, with some drawbacks. The most obvious benefit is not downloading any software to your computer. This will limit where you can play, as you will have to download it on every computer you play on. Take a look at some of the advantages and disadvantages of instant play casinos.
