About casino software providers

While online casinos host gambling software and allow US players to launch these games for real money, receive bonuses, make withdrawals, and do all other things of this kind, the duty of casino providers is to develop software from scratch. Certain companies may be focused on particular software types. For example, ViG focuses on only live dealer games, which allows the brand to develop its live studios, use streaming tools of high quality, and apply new trends to its products. 

Other vendors may work both on online slots, including jackpot ones, and RNG table games (these titles aren’t powered by dealers). One such example is Betsoft which has both fascinating slot machines (eg. A Christmas Carol) and popular table games like online roulette (eg. American Roulette) and online blackjack (eg. 21 Burn Blackjack) in its catalog.

In some cases, the vendors can be working in several directions. For example, Arrow’s Edge is known for a range of engaging online slots like Robin in the Woods. But it’s also working with the Vivo Gaming live dealer studio to deliver live games to American players. In addition, its library includes some RNG table games like European Roulette and Blackjack Single Deck.

Mainly, these online casino providers have official sites with information about the brand and its games (available bonus features, RTP, volatility, etc.). Besides, these sites can display new releases and gambling news connected with the company. On most gambling sites, casino game software can be sorted by suppliers.

Proprietary software explained

The model when providers are engaged in software development, while operators are working on promotions and other gambling services, is true for most cases. However, proprietary software online casinos choose a different way to go. Some casinos may produce games of their own which are usually marked as exclusive games. These can be both slots and table games, including live solutions. 

The main advantage of such an approach is originality. As for advantages for operators, they can save money and control all the processes themselves, so any issue can be solved instantly. But it’s quite consuming to work on such software when a company doesn’t have enough facilities and opts for outsourcing. This means that such software is a unique feature rather than something ordinary. And it’s normal when proprietary software online casinos have several exclusive titles, while the entire library is completed by the providers reviewed on this page.

Popular casino software providers in the USA

Here in the USA, the industry has enough skillful vendors to develop top-notch software, including both slots and table games. Most of them deliver mobile-optimized titles based on HTML5. Plus, the majority of these games can be played both for USD and crypto (Bitcoin and other cryptos). Below, you’ll learn details about the leading vendors providing software for online casino sites in the USA.

Choosing the best software provider

For some players, it’s a good idea to open a reliable US online casino and launch a random game. However, when you are attentive to detail and want to pick a title according to your preferences, it’s worth using filters by online casino software providers and learning more about the suppliers you are going to test. For this purpose, you can use the steps over here:


Examine the game library

You can do this either on the provider’s site or at your online casino when picking a certain provider from a dropdown menu (pretty often, the casino may have only some games from the vendor, so the second option will give more relevant results). Check whether the catalog is large enough and features the game types and themes that suit you.


Try out the software for free

Mainly, US online casinos allow gamblers to launch their games in a demo mode after registration. This mode is designed for players to understand the game mechanics and play for free with no risks. Pick the game you like (except for live dealer titles) and test it without spending a dime.


Learn more about bonus features

Pretty often, certain providers are associated with bonus features available in their software. For example, Pragmatic is known for the Tumble feature in its games (eg. Sweet Bonanza), while Betsoft and RTG are adored for progressive jackpots (eg. Greedy Goblins and Cleopatra’s Gold).


Find out about current tourneys

Regularly, providers together with online casinos in the USA can arrange tournaments with thrilling prizes. Plus, certain games can be involved in large events held by the operator. If it’s so and you like tourneys, you can earn points and hunt for extra rewards when playing these games for real money.


Don’t stop on a single brand

When you’ve picked your favorite, that’s great. But this doesn’t mean that you should pass by other talented suppliers. Try out different software for online casino sites and make sure you are aware of new releases with innovative options for American players.

If you want to learn more about the achievements of a certain brand in the gambling sector, visit its official site and learn more about the rewards of global iGaming exhibitions and the partnership with other reliable companies. Actually, it’s worth following these steps when you are choosing a US online casino as well. This way, you will make sure that the casino has enough available vendors and games to cover your gambling needs.

Proven fairness and reliability

Dealing with real money is always a serious issue. First, US gamblers must choose a licensed and reliable online casino. Actually, when an operator is licensed in the USA, this means that it’s home to fair casino games. But how to make sure that the games you play are not rigged and feature outcomes? Let’s learn more about safety measures by considering the example of RNG software online casinos.

RNG is known as Random Number Generator. This mechanism is used to determine random outcomes according to the declared RTP on games offered at safe and secure online casinos. And organizations proving that the RNG is correct are independent third-party labs operating worldwide:

  • iTechLabs

    Testing online gambling software since 2004, this organization is known as one of the leading accredited testing laboratories worldwide. It provides RNG/RTP output audits, annual & security audits, and more.

  • ecogra


    It’s another leading independent and internationally approved testing agency established in 2003. Its focus is on the certification of online gaming software and related systems.

  • gli


    It’s a pioneer in the gambling certification area since the company was established in 1989 and managed to test millions of land-based, online, and lottery device and system items. It sets global standards for the industry.

  • bmm

    BMM Testlabs

    This organization is known as the longest-established in the industry since it was launched in 1981. It employs about 300 people in 13 global locations and serves over 400 jurisdictions.

Due to such tests and independent audits, iGaming developers can prove that their online casino games are random and provide the declared payouts according to the determined RTP. Moreover, the games are tested not only when being released but also on a regular basis. Pretty often, the logos of these testing labs are displayed in casinos’ footers. Besides, you can find out about these tests when visiting the official sites of these providers.

Return to player in games from top US providers

As we’ve noticed, RNG tests must prove that the RTP of the tested games is working properly. But what’s RTP, and why is this score essential for US players? RTP, or Return to Player rate, is a percentage casinos pay back to players. This means that the rest of this amount is the house edge. The best games are the ones with an RTP of 96% or higher. Of course, there can be exceptions for progressive jackpot games where the RTP is lower since a certain amount from each real money bet is added to the prize pool.

Let’s take a look at the example. The 4 Seasons slot from Betsoft has an RTP of 95.3% (yes, this rate is not the highest out there). When Americans place a bet of $100, $95.3 is paid back to players, while $4.7 is the house edge (an amount the real money casino earns). But this doesn’t mean that you can calculate your potential wins this way. The thing is that hundreds of players can place bets on this slot at the same time, and the bet amount may vary. Moreover, the wins are distributed randomly, so one player can win, for example, $50 from a $1 bet, while another player may lose a bet of $50.

Considering the mentioned details, the house edge always takes place, so gamblers need to play responsibly and manage the bankroll wisely. But, of course, it’s best to choose slot machines with the highest RTP. Here are several examples players can find at US online casinos:

✅ Swindle All the Way (RTG) 98.5%
✅ Good Girl Bad Girl (Betsoft) 97.79%
✅ Snow Leopard (WMS) 97.75%
✅ Who Spun It? (Betsoft) 97.64%
✅ Mermaid Queen (RTG) 97.5%
✅ Reel Crime: Art Heist (Rival) 97.03%
✅ Lucky Fishing Megaways (Pragmatic Play) 96.97%


When we are talking not only about slots but also about table games, the ones with the highest RTP are video poker and blackjack. For example, Jacks or Better (99.54%) and American Blackjack (99.60%) from Pragmatic Play, Joker Poker (98.6%) from Rival, and Aces and Eights (98.65%) from RTG. Sometimes, information about the RTP rate is displayed in the game’s settings or on the provider’s official site. But in some cases, this information isn’t available, and you should read reviews of these games to find out such details. 

Bonus features in the best casino software providers

Slot machines without bonus options are quite rare since even classic 3×3 titles feature bonus symbols like Wilds (or Jokers) quite frequently. Moreover, online casino software providers are doing their best to add exclusive and innovative options to their games. The most popular features are free spins, respins, various modifications of bonus symbols (eg. Roaming or Sticky Wilds), multipliers, gamble round, pick-an-item, Cascades (also known as Tumble or Avalanche), Megaways, Ante Bet, Bonus Buy, and, of course, progressive jackpots. Let’s take a look at these features on the games from the most popular online casino suppliers in the USA!

  • Free spins

    What about bonus spins you don’t pay for? Yes, that’s the concept of free spins in online casino slots. Mainly, they are triggered by Scatters. In some cases, the number of spins varies depending on the number of bonus symbols. Plus, these rounds are often re-triggerable. For example, 3 Genie Wishes from Pragmatic Play has a bonus round with two variations – 6 free spins with Sticky Wilds or ten free spins with Raining Wilds.

  • Respins

    Unlike free spins, here, you get only one single spin (or just several respins), but it’s still beneficial since you get it for free and at your current bet. In most cases, respins are triggered by certain bonus symbols or as a result of a particular combination. For example, on the Zeus 2 slot from WMS, US players can enjoy the Hot Hot Super Respin feature. When the Zeus symbol covers the entire reel 1, two Hot Super Respins are triggered.

  • Modified bonus symbols

    Wilds and Scatters are the most frequent bonus symbols you may meet. But it’s more enjoyable when these symbols are modified to add more features to the gameplay. For example, Nights Of Fortune from Spinomenal has Wilds, which expand to cover the entire reel when landed on reels 2 and 4 simultaneously. And Flying Hippo (Pragmatic Play), released in 2023, has Colossal Wilds with multipliers of up to 50x.

  • Multipliers

    When your bet is increased by the symbol value and extra multipliers, it’s super beneficial. Mainly, multipliers are attached to Wilds or provided in bonus games (during cascades or free spins). For example, Kung Fu Rooster from RTG has the Fire Claw Multiplier option where the multiplier increases with each new free spin, coming up to 25x.

  • Gamble round

    It’s a popular feature available on many traditional slots at online casinos in the USA. Mainly, the feature is available once you get a win. Optionally, you can agree to try to double your win. In most cases, you need to guess the color of the face-down card (2x for the right color or 4x for the right suit). However, these mechanics may be very different. For example, a ladder when you go up or down, or gamble rounds when you need to get a higher card than the dealer has.

  • Pick-an-item

    It’s a bonus game where you pick an item to reveal your prize. One such feature is available on License to Spin (Arrow’s Edge). Here, you can launch a bonus round with cocktails where each martini glass has a certain value. Once the prize is revealed, you can either collect it or get another glass, trying to get a larger reward.

  • Cascades

    This feature may also have other names like Tumbles or Avalanches. You can experience it on slot machines from many providers, including Pragmatic Play. Its concept is that winning symbols burst, which allows upper symbols to fall into their place and create new winning combinations.

  • Jackpots

    These can be fixed and progressive jackpots, depending on your chosen game. Providers that can boast such features are WMS (eg. Raging Rhino Rampage, Mini to Major fixed jackpots), Arrow’s Edge (eg.  Medusa’s Millions Hold & Win, progressive jackpots), and Betsoft (eg. The Glam Life, progressive jackpot).

  • Other bonuses

    Actually, this list can be endless since casino games software providers keep on inventing new options to please US players. Ante bet (eg. increased by 20% or 25% on Gates of Aztec released in 2023 by Pragmatic Play) is beneficial for players who want to increase their chances of getting free spins or other features (mainly, the option is available on slots from Pragmatic Play), while Bonus Buy is appreciated by those who want to get the desired round at once (eg. Fire Archer from Pragmatic Play, the bonus costs 100x the bet). The layout of some games may be unusual (eg. 3-4-5-4-3 on Helena’s Haunted House from Arrow’s Edge). Winning mechanics may also be different. Pragmatic is known for its numerous Megaways titles (eg. Mammoth Gold Megaways) and games based on clusters (eg. Hot Pepper).


The overall experience of US players depends on the skills of gambling developers providing this software. This way, Americans access free spins, progressive jackpots, titles with a high RTP, lots of table games, and a range of live solutions. The fairness of RNG software online casinos is proved by both licenses obtained by online casinos in the USA and certificates from independent third-party labs. The most popular brands you’ll meet at US online casinos are Rival Gaming, Pragmatic Play, Saucify, RTG, Betsoft, and more. Choose the most attractive gambling site and enjoy feature-rich games from the best online casino game providers in the USA.
