The Best Casino Software Developers

Online casino software providers bridge the gap between the creative minds making our favourite games and us players enjoying trying them out. The essential components of a great game are multi-faceted, we don’t only expect unique slots themes. Modern players are after interesting casino games variants, fantastic graphics and high octane sound to draw them in. Whether software needs to be downloaded rather than playing straight in the browser is another consideration. Fundamentally, the prime job of the software developer is to provide a solid foundation for safe and secure games, including mechanisms which protect players from losing their bets during a software crash for example. Read on for a summary of the best casino providers.

Can I Play at the Online Casino Without Downloading?

This is asked so often, I’ll be direct and say, yes, playing games in your browser is the standard. Download games are only available for Windows, and from few providers, the same is true for apps, you won’t be expected to download each game to your mobile. The no download, instant play online casino is now the standard.

Who Develops the Best Online Casino Software?

I’ll begin by distinguishing between online casino software providers and pure game developers. Indeed, they complement each other but cater for different parts of the game production process. For the online casino providers, it is far too much effort to developer their own individual software, therefore they rely on specialised games software developers. These games providers do a great service in providing a secure platform for the games to be launched. For more information on which provider’s casinos work with, head to my casino reviews page. The games themselves are developed by specialist casino software developers. It’s common for casinos to cooperate with a bunch of manufacturers, which is the ideal scenario, giving a fantastic variety of stimulating games, where players can profit from the different strength of each developer. The effect of casinos choosing from the same ‘pot’ of developers has a nice knock on effect. The individual jackpots of games grow far higher since they aren’t contributed to from just one casino’s players, but across every casino which also hosts the game.


Playtech is the undisputed champion and heralded as the best online casino software provider. This market-leading brand gives visitors to Playtech casinos the choice of downloading software or playing straight in your browser. They stand out from the pack because they hold the exclusive right for numerous licenses for blockbuster films. Collaborating with Hollywood was a genius move and a has been a great source of success for Playtech. The progressive DC Comics jackpot games and standout games such as Batman and The Joker Jewels have been a raging success amongst slots players.

Around since 1943, WMS are one of the longest running games developers. Native to the US they provide some of the most popular land based slots, and for us in Europe, they’ve channelled their focus upon online expansion. They’ve made this leap like a fish to water producing some epic slots including the action-packed Bruce lee, or endless variations on the Star Trek theme, all available uncomplicatedly straight in your browser.

Play’n GO

The Swedes are a talented bunch, with another company from their fine country making my list of the best software providers.  Games known all over the world are made in the small town Växjö, producing hit games with strikingly diverse themes, Cop’s ‘n Robbers is one of my top picks. Play without downloading in safe hands since Play’n GO are small but endorsed by all major gambling regulators, the UKGC and IBAS to name a few.

Betsoft Gaming

Now onto a relatively small team making big things happen from their native land of Malta. The team behind Betsoft pride themselves on bringing ‘cinematic experience’ to the reels. A combination of epic graphics and 3D software make for some seriously impressive games. Take Birds and Frankenslots Monster as just a taster of their expertise. These games are so detailed at first glance, their easily mistaken for a Pixar film.


Dublin-based Cryptologic are also long standing in the online casino software providers industry. Around since the online casino scene blew up in 1996, this company began had humble origins, conceived by two teenage brothers in their Toronto basement. They’ve come on leaps and bounds since the early years, listed on the London Stock Exchange, in 2003! With slots like Cleo: Queen of Egypt, Savannah Sunrise under their belts, it’s no wonder they’ve been such a success.

Instant Play in the Flash Casino or Download?

The question is, is there a benefit to downloading software over playing in the browser. I’m happy to say no, there are no significant advantages from downloading software and not many of the best casino providers offer this. Nevertheless, users with a slower internet connection will notice a slight difference when downloading software since they will experience quicker download times and slightly smaller data volumes with the download software. Fast internet connections are experienced through the UK, so this slight advantage on the domestic computer has been lost in recent years and the first choice for most players is playing games directly in browser. The are some tangible benefits to playing in browser, you can login to any internet ready terminal any time without problems, there’s also the possibility to offer more several providers under one roof, which isn’t possible with download software.

Play in BrowserIt’s easy and fast to play a game on any computer or device
You can login anytime and anywhere and launch the game
DownloadWith slow connections, loading times are quicker for games
Less data volume is required for playing downloaded games

In relation to downloading mobile apps, the story is a little different. Obviously, connection speed and data volume are factors for consideration, however, with casino software app providers benefiting from HTML5 support, instead of relying on the obsolete flash casino, there seems little point entertaining the download software, saving space on your portable devices.

The Random Number Generator

Random number generators, or for those in the business RNG’s are the cornerstone of a transparent and smooth running online casino. Software developers have regulatory bodies check the random distribution from playing over a lengthy period, this can exceed a million turns on a slot, or rotations of the roulette wheel for instance. Any mistakes in the distribution can be quickly spotted and exploited by players or hackers, or from the other side, be detrimental to players. Any irregularities are spotted by a complex mathematical algorithm for the benefit or both the casinos and their users.

These so-called regulatory bodies must be independent, you don’t have casino software developers checking their own stats and handing the information back to the casino. Examples of the key players include eCogra, Technical Systems Test (TST) and Gaming Laboratories International (GLI). Casinos with pass certificates from these auditors can be trusted without doubt, and most casinos are proud to display monthly reports with their detailed games RTP values.

Software Security

One of a Casino top priorities is security, they can’t be licensed without meeting minimum security standards. To meet the conditions required, they partner with external agencies. These cover all sorts, from protecting player’s data, SSL encrypting real money transfers, as well as anti-virus defence, working with big names McAfee and Norton. Often the logos of these well knows agencies are stamped across the company homepage footer, with clickable links to their respective homepages so you can be sure that the partnership is official.
