It’s not easy finding the best online gambling software, safe online casinos and top games that are ready to burst out that big win, but we found the answers to all of your questions and we’ll divulge them for free. 

Casino gaming software is super important, that’s the head of the gambling “beast” if you will and from there on you go straight to online casinos (the body) and then branch out in different kinds of games (slot games, table games, live casino games etc) that are the beast’s hands and the beast’s legs which are made up of winning strategies.

Consequently, before figuring out everything else you have to dissect the head and see what it’s all about, what casino software providers are, how they are connected to online casino sites, how they control the gambling world and more. So let’s dive right into it and see how you can get from not knowing almost anything about the gambling industry to being an expert and improving your winning chances.

What Are the Best Casino Software Companies?

Just as Apple and Microsoft create software for your phones and computers, software providers of the gambling industry create the casino games you love. Casinos software companies are in charge of the whole thought process behind the game, the mathematics part, the RNG (random number generator), the RTP (return to player), the graphics design, the sound effects, the theme, everything from the beginning to end.

There are hundreds of game developers in the gambling industry and each of them gives its games to a few select online casino sites. The most popular software providers have more casinos than those that have just started out or aren’t as popular. 

Below you will find the best software providers of the online gambling UK industry with information about them as well as top casinos for each of them. If you want to learn more about each provider, click on each subheading’s name. 


Microgaming is one of the best online casino software providers and one of the oldest ones since they’ve been on the market since 1994. They were the first ones to launch mobile casino software, back in 2004, and have kept growing through the years and making better and better slot games.

Casino veterans know that in the old days players used the presence of Microgaming slots in an online casino as a mark that the casino was safe, fair and legal. The same thing still applies today, many years later, and you can confidently try them out as we’ve never encountered a Microgaming casino that wasn’t a good choice. 


NetEnt is one of the biggest software providers and the company has been dominating the market since its launch in 1996. They’ve had such impressive growth in man-power, the number of games and overall quality that they’ve become synonymous with epic graphics and innovative bonus features and game mechanics. They are one of the most beloved software providers and, for that reason, you will find plenty of NetEnt casinos which we recommend you check out!


Born in 1999, Playtech is a giant that has created over 500 online casino games (not just slots, but also other impressive casino games like live casino games, table games, video poker, lottery, bingo and more).

They are mostly known for their exceptional slot games that feature a Marvel or DC Comics theme with impressive superheroes guiding your way to epic bonus features and huge progressive jackpot wins.

Launched in 2006 (so younger than most top providers), Betsoft is the leading game developer when it comes to 3D graphics. The reason why there are so many great Betsoft casinos is that they are one of the first developers of 3D slots through their Slots3™ project and that truly set them apart from their competitors.

You’ll easily be able to set Betsoft games apart from others, pick a casino and test this theory.


GreenTube is a software provider that has over two decades of experience and since 2010 when they became part of the Novomatic Group they’ve really come into their own, so much so that they became the Novomatic Interactive division.

What Is the Safest Online Casino?

Safety is super important when picking an online casino to play at. There are several factors you need to take into account to make sure that the online casino you decide to play at is perfectly safe. The first you need to look for is the license of the casino. There are several licenses and each of them works for certain jurisdictions. 

While the UK Gambling Commission is the one that’s toughest to get and most respected commissions that regulated the gambling world, this license is only perfect for UK players. A Swedish license will work for Swedish players and so on. Make sure that you know under which jurisdiction your country falls and look for that particular license, be it UKGC, MGA, Gibraltar etc.

Another important factor is SSL encryption. 128-bit SSL encryption is the industry standard. If the casino you choose doesn’t have the little lock sign next to its link on the left side then it’s not secured and you shouldn’t play there. This encryption is the extra protection that will ensure that your personal and financial data is safe and can’t be accessed by any third parties.

Players asked if 888, Casumo and Dunder are safe and we’re here to tell you that yes, they are safe, they have top-notch licenses, are fully regulated and safe and have state of the art encryption technology. You can play at these top casino with no worries.

What Are the Best Online Casino Sites?

Each casino is different as is each player so everyone can theoretically have a different favourite online casino that fits all their needs. 

There are several things that an online casino site should have to be considered the best:

  • License and jurisdiction
  • SSL encryption
  • Top software providers
  • Great selection of games
  • Nice promotions
  • Great customer support available 24/7
  • Many payment methods

If you’re looking for the best online casino sites accepting UK players you will find them on SlotsCalendar and they also have a review which will go through all those things stated above so that you will easily and quickly know which casino fits all your needs. 

What Is the Best Game to Play at the Casino to Win Money?

With hundreds of software providers obviously there are thousands and thousands of games you can play. The first thing you have to decide for yourself is the kind of casino game is best for you. It’s no easy feat to choose between live casino games, table games, slot games, bingo, lotteries, scratchcards and others. 

But if you want us to hit you with the facts to help you decide, we’re ready:

  • Slot games are by far the most prefered casino game by players from all over the world.
  • If you’re playing progressive jackpot slots and you win you’ll get the biggest possible prizes, bigger than all the other casino games could offer (unless you’re a high roller who likes betting millions per hand in which case you can win huge sums at all games).
  • Slots offer the most simple gameplay that’s solely based on luck, not strategy, so you don’t have to learn complicated rules. 
  • Slot games offer the most diversity. While other games are pretty much the same thing with minor differences, slots have different themes, different kinds of graphics, gameplay and bonus features.

So, if you ask us, slots are definitely the best way to go when playing at a casino. This doesn’t mean that you can’t try other games and that they aren’t good. You can switch between games as much as you want. 

Which Online Slots Payout the Most?

Even if you decided to play online slots, how do you decide which one to play out of the thousands available? You could go for popular classics like:

You could go looking for the best payout Microgaming slots or top slots from each software provider. 

But the best thing to do is find that perfect sweet spot where the game has the theme, graphics and bonus features you prefer and also the best possible payouts.

To find the best payout slots there are several things to consider:

  • RTP (return to player)
  • Slot’s volatility
  • Slot’s top payouts
  • If it does or doesn’t have a progressive jackpot
  • If players win on that slot often

The RTP should be as high as possible (preferably never under 94% and as close to 100% as possible). The volatility should be low if you want small prizes often, high for big prizes seldom or medium for constant wins. Look at the paytable of each game to see what their maximum payouts are for each combination because some might surprise you (either positively or negatively). 

The presence of a progressive jackpot can greatly influence the game. While you can win truly life-changing money, the odds of this happening are quite low and it will lower the RTP and raise the volatility so think well before choosing a progressive.

Ultimately, everything is your choice, but if you see that other players are constantly winning at some slots, maybe look into that. 

Conclusion – What to Play, Where to Play, How to Win?

Can you win money on online slots? Which are the best software providers? Is X the best mobile casino? What are the best online casino bonuses? These are all valid questions which every player is thinking about and the answers to all of them depend on each player. 

Can you win money playing online slots?

If you are playing them for real money (with or without a bonus) you can win real money. The chances of winning depend on your luck, there is no way to cheat at slot games and make them payout when you want them to. If you’re playing for fun in demo mode you only win experience, but not real money.

Which are the best software providers?

The ones we stated at the beginning of this article are unanimously prefered by players from across the globe. While they may be extraordinary and have games that tick all the boxes, you might still love other providers as well (Personally, we totally love the new software providers that are just starting out but coming at us at full speed). No one will judge if you say you love Yggdrasil or Endorphina or any other software provider, you can pick whatever makes you happy.

What is the best online casino?

The best casino is the casino that offers you everything you need for a relaxing gaming session with no worries whatsoever, the one that requires the least amount of effort and the maximum amount of fun. The combination of bonuses (no deposit free spins or no deposit bonuses or whatever floats your boat), of games, providers, payment methods, customer support and anything else you’re interested. We have a top casinos list (which we update constantly) so if you’re looking for inspiration check it out.

What are the best online casino bonuses?

You could love no wagering bonuses, no deposit free spins offers, no deposit cash bonus codes, huge deposit bonuses or whatever. We’re not here to judge and neither are other players. If you feel like you have the most fun and get the most wins out of cashback deals, do that. If you think that deposit offers make more sense for your style, choose that. All bonuses are great as long as they have fair wagering requirements and terms and conditions.
