Best Online Slots By Software 2024 (with links to free games)

Best Online Casino Slots Software Providers Compared

Each online slot machine software company has their own unique history and background. Moreover, they've each been around for different periods of time, and some of them were even producing brick and mortar titles back before playing online existed. It's easier to pick from the different software options when you know which games they produce. Below, we look at several of the top slot software developers, their popular free games, and what they bring to the table.

Slot Machine Software Developers Offering Unique Features

One way that online slots software providers differentiate themselves from each other is by coming up with innovative features. While these can sometimes be licensed by the competition, they're still used as a key point in the argument as to why they are the best. No review of any individual software provider can be complete without pointing out what they have done to innovate in the industry as a whole, and we want to make absolutely certain that players know what some of the biggest names have done on a larger scale in this way.

• 

  Big Time Gaming

  Back in 2011, Big Time Gaming (or BTG for short) opened up their doors with a focus on offering one of the best gambling experiences available to players. Their Megaways style slots really helped to pave the way to making that dream a reality by putting a random number of symbols on each reel within an "all ways" layout for tons of ways to get paid. Now a part of the Evolution Gaming Group, their Megaways layout is licensed and used by lots of other slot machine software companies.

• 

  Push Gaming

  Many players take mobile apps for granted when looking at slots casino software. However, Push Gaming helped to really push for games on the HTML5 platform, getting away from Flash, which ultimately led to the modern environment where you can take your play with you wherever you go for virtually any top provider. This was their goal since opening up in 2010, and it's clear that they have achieved that goal since it's now the industry standard. Players can enjoy some excellent titles including Jammin Jars a popular music themed slot.

• 

  Quickspin

  In the modern space, quality is the name of the game. However, when Quickspin entered the industry in 2011, that wasn't the case for a lot of what the industry was putting out. At the time, it seemed like most 5 reel slots rehashed the same themes, and if you were to play one title, it might seem like a few other recent releases. What Quickspin did was establish a much higher standard for both graphics and gameplay, which was largely spread under their work with Microgaming (now Games Global), throwing down the proverbial gauntlet to the competition.

Licensing and Fair Gaming

Licensing is one of the most important things that players can look for to make sure that a provider and its games are handling things in a fair way. No matter if it's a live location like Las Vegas, or if it's online slots that you play on your phone, you want things to be fair in terms of payout rates. The various entities that handle this have different degrees of reputations, and knowing where your favorite provider is licensed can give you a better understanding of what level of accountability to expect.

Licensing of Online Slots Software Providers

Below, we have taken a quick look at the most well-known regulatory bodies. No matter if it's the latest company with a new game or a classic provider that has been in the industry for decades, you'll want to know which of the following they are licensed by and the status of that license. Playing slots from software providers licensed by trusted entities makes it easier to secure a withdrawal and keep your winnings after playing.

• UK Gambling Commission (UKGC) : Generally considered the top regulator in the world, they are super strict with how they handle fairness from software developers. What's more is that they have shown that they are not afraid to lay down massive fines if their rules are violated. This leads to a tremendous level of accountability that gives players a serious level of peace of mind.
• Malta Gaming Authority (MGA) : Aligned with the UKGC, the MGA is also a top-tier regulator that has a history of holding both individual casinos and software providers accountable. With regular software audits and other checks, including for the RNG software that runs everything, this is a name that players can trust.
• Curacao e-Gaming Licensing Authority : This one isn't quite as strong of a name, and their primary claim to fame is that they're cost-effective for sites and providers because they do not cost a lot of cash to get a license up and running. Generally speaking, we recommend players exercise caution when betting at locations licensed only by this particular entity if they don't have a long-running reputation for taking care of players.
• Gibraltar Regulatory Authority (GRA) : The GRA has a solid reputation for being serious about their rules and standards. While they don't make the headlines for big fines like the UKGC, they are still seen as a particularly reputable body, and players can trust that this entity will revoke the license of any online slot machine developers that operates outside of their guidelines and policies.
• Kahnawake Gaming Commission (KGC) : While this licensing entity isn't seen on the same lower level as Curacao, it's also not held in the same esteem as the UKGC, MGA and GRA. Occupying a bit of a middle ground, they have a checkered past to some degree. We would generally require that a KGC-licensed site has a reputation of their own for giving players great service and being reliable before playing there.

RNG Certification for Fair Gaming

No matter if you're a recreational player who plays for fun or if you're a serious bonus hound looking to take advantage of slots bonuses like no deposit codes, free spins and other goodies, you want the RNG to be fair. This is especially important if a lot of money was involved, like with progressive jackpot wins. Various independent, non-licensing entities are in place that do just that. While each provider has their own custom approach to how they handle RNG programming, these independent entities listed below test them each individually to ensure fairness.

• eCOGRA : An eCOGRA certification means that the provider has passed rigorous testing to show that its RNG is completely fair. This generally matches or exceeds the standards required by most regulatory bodies, and since they test regularly in an ongoing way, it helps to make sure that you know you're playing with somewhere with a fair RNG no matter if you're a penny player or a high roller.
• iTech Labs : Their specialty is RNG testing with a focus on the mathematics involved. A part of this is that they require slot game developers to give them access to everything to do with their code and programming to make sure that it's built properly from the ground up. If they pass iTech Labs testing, then they have passed some of the most difficult tests in this space.
• Gaming Laboratories International (GLI) : This independent testing lab offers certifications and compliance assistance with various gaming regulations and standards to make sure that the RNG and other aspects of the slot software is within the rules no matter where you're playing. Their specialization centers around making sure that software (particularly the RNG) fits within the bounds put out by the different regulatory bodies.

How to Choose the Best Slots Software

Most software options in 2024 have "no download" platforms that allow you to play without downloading anything. If you're playing slots for free with demo games, no registration is required to begin with, but whether you want to sign up at a site to play or not, you'll want to figure out your preferred software developers ahead of time. Here we offer some things to consider that will make it easier to pick out what works best for your preferences.

• Software Type : Major players like IGT, NetEnt and Playtech all offer in-browser play with no download required. This allows you to play from virtually any computer, and a mobile app can also be available.
• Game Compatibility : The titles available depend on which providers are available. Some developers have platforms with several other partnered providers, providing compatibility for the entire bunch no matter how you play.
• Language : Most titles don't require you to read that much, but getting the instructions (especially on features) in your language can be helpful. Different providers offer support for a different range of languages.
• Licensing : Look to see where a provider is licensed. This will help to make sure that your payouts are fair, wins are proportional to the number of coins wagered and so on.
• Game Variety : Some names focus on one type of title, but others have more of a variety. This goes beyond the total number of options they have available and extends to the slots themes, feature sets and play styles involved.
• Graphics : There's not really a reason in modern times for new games to have poor graphics. The industry standard is for everything recent to have a great aesthetic, but stylistic choices can really make a big difference in what you see between development houses.
• Audio : For some online casino slot software companies, sound effects and music are an afterthought. For others, it's a critical part of the overall experience.
• Stability : It's never fun when software crashes, especially when you're in the middle of a betting round. We recommend players stick to options that have a reputation for software stability.
• Country Restrictions : Some providers do not operate in particular countries or regions. We would advise players to make sure that a developer's games are available where you're located ahead of time.
