The Best 7 iGaming Software Developers The world of online casinos is a battleground, hundreds of sites exist, and new ones join the fight for the number one spot every week. Fuelling the armoury of each casino online is the software developer. Casinos do not make their own games, instead, they hire out the work of developers who, in turn, stock the casinos with hundreds of games from their portfolio. But who are the best in the business to invest in, and as a player invest your time and money with? The casino is just a shop, a seller of goods that allows you to win real money. Here we are presenting players with seven of the best online casino software developers that have helped innovate and guide the casino industry to the levels of success and quality that we all see and enjoy now.

Creating Casino Software

Of all casino games, slots are the most popular by some distance and meeting the supply and demand of all this is the developer. There are thousands of games already in the market, every idea, style, theme, everything already seems to have been made and it is upon these gaming companies to create something new, different, and innovative each time.

It’s a hugely important area of gaming that players should know about because it can be of benefit to know which developers are making their games profitable to play, and which are making them harder.

We spoke with Eija Virtanen, Editor-in-Chief at online Casino, to discuss the advantages of learning software development and how they use the information to make players in Finland aware which has led to more prize payouts being won by Finnish players. 

“It’s all about the software, the software tells you so much about the game, how it will payout and how it will perform overall as an experience. Most players will think it is all about luck, but the fact of the matter is, that these games are built a certain way that luck never really becomes much of a factor in terms of results. We tell our players in Finland that before playing to check the game’s RTP first and to play demo games to recognise the volatility of a game first before playing it in a Finnish online casino.”

The RTP within gaming is the Return to Player algorithm, this dictates what percentage of money is kept by the casino and what is paid back out in winnings. An average game with a score of 95% RTP, means this is the percentage of money put in, that is paid out in winnings. 

The volatility of a game is based on programming settings that dictate the performance and there are three levels of volatility: Low, Medium, and High.

The Low setting makes games more frequent in their payouts, but the amounts are low and often less than the wager amount per spin. The High setting performs fewer payouts but are of a higher profit amount. Medium is somewhere between both in performance. 

7 Best Casino Software Developers Online

Now, all casino games are built with the same programming inside, so how can the best be distinguished? Well, there are some key factors. The consistency in their development, their range in innovation, whether their games are entertaining and how profitable they are. With the help of Eija Virtanen at, we have created a list of seven developers that are clearly ahead of the game when it comes to online casino development.

7: Play’n GO

Having formed in 2005, Play’n GO are relative newcomers given the list of developers out there in the market. In over 15-years, they are one of the game-changers in the industry. Famed for focus on quality rather than quantity, their games try to push boundaries in innovation more than most out there. This may have hampered their popularity at a player level, but within the institute that is online casinos, those that know of the gaming demands know how good their games are and how important. Viking Runecraft was a game-changer, bringing games with levels to progress through, a first of its kind and brought players colossal gaming grids which at the time were unseen. Most definitely worthy of a place on this list because many out there copy them and get more unfair attention.

One of only a small number of US lead businesses making slots for land and online casinos. IGT are the epitome of corporate America, with games that are bigger and more different from other developers out there. They believe big is better in the US and slots are the same when it comes to this idea. Their games capture American pop culture perfectly, but it’s their brand which is identifiable and they are the only developer with their own unique look. Compare most slots side by side and they will look the same 90% of the time. IGT games are different, vertical in format and looks just so American, if possible. They have won it all and have also appeared in the Forbes top 500 list, the first iGaming company to do so. The Best IGT Games:

The Megaways product is seen everywhere and it’s not one specific game, it’s now dozens of them. Megaways started as a new form of slot. Players got more symbols and more paylines, reels were removed and replaced with blocks that when forming a winning line, would be removed from the game, and replaced with added symbols that could potentially form new win lines. The benefit of which comes from the fact that these auto wins did not cost any spin money. The success of this Megaways led to other companies teaming with Big Time to produced revamp titles under Megaways gameplay. The Best Big Time Gaming Games:
