Best Software Providers for US Online Casinos

Americans don’t have as many real money gambling sites and apps to choose from as other international markets. But some of the options they do have are first-class.

There are a few excellent US sports betting sites, and several of the online casinos accepting players from the USA are just as good as those available elsewhere.

Part of what makes the casino sites so good is the games. The best software providers for US online casinos offer cinematic 3D slots, storytelling titles, instant jackpots, and more.

Not only do the most prominent game developers for the United States market have longevity in the industry, but they have created custom product lines with recognizable gambling opportunities.

Americans who use online casinos and gambling apps tend to make their selections based on collections like Real Series slots, I-slots, and Slots3 titles.

Even the top live dealer provider for online casinos in the US has a proprietary blackjack game and unusual camera angles following the cards as they hit the table.

Let’s take a look at these companies and what they have to offer.

RealTime Gaming

  • Year established: 1998
  • Location: Began as a US-based company in Atlanta, Georgia but moved to Costa Rica in 2006
  • Number of games: 300+
  • Highlights: Real Series slots, boiling point jackpots, retro-inspired licensed brands

RealTime Gaming (RTG) didn’t become one of the best software providers for US online casinos by sticking to the same old, same old. Instead, RTG focuses on surprise and boiling point jackpots, plus unusual player insurance policies.

While RealTime Gaming has a 300-game collection, it is best known for its Real Series slots with random jackpots. The instant prize awards come out of virtually nowhere and without betting constraints.

Everyone playing Real Series titles, like Enchanted Garden and Cash Bandits, are in the running jackpot-eligible, regardless of stakes.

Here are some examples of games in the Real Series collection.

Real Series Slot Paylines Special Features
Cash Bandits 25 Vault Feature unlocks free spins, double-pay bonus wins
Cleopatra’s Gold 20 Wild multipliers, triple bonus payouts
Aladdin’s Wishes 20 Wild multipliers in the base game, magic lamps with cash prizes
Caesar’s Empire 20 Scatter pays, wild multiplier, double-pay bonus wins, scatters morph into high pays
Enchanted Garden II 25 Adjustable paylines, two bonus rounds, bonus win multipliers, extra bonus wilds

There are other RealTime Gaming slots with progressive jackpots besides the Real Series games, including Megasaur and Aztec’s Millions.

Some of RTG’s newer titles feature an exciting progressive jackpot system called “boiling point jackpots.” Spirit of the Inca is a prime example, with five awards that have must-hit ceilings.

Aside from the jackpots, RealTime Gaming is known for its Feature Guarantees, that function like mini-insurance policies.

A Win-Win slot assures players that they’ll exit bonus rounds with plenty of cash benefit. The Feature Guarantee has a bonus or modifier trigger built-in, so patience isn’t required.

RTG also offers games other than slots, including several blackjack variants. If you’re interested in trying them out, the top US online casino with RTG games is Las Atlantis.

  • Year established: 2005
  • Location: Cyprus
  • Number of games: Over 200
  • Highlights: I-slots, classic three reels, Rival Alive 3D

Rival Gaming is fond of slot storytelling. Its trademarked I-slots concept solidifies Rival’s place amongst the top software providers for online casinos and gambling apps accepting USA players.

The custom I-slots play out like a television series, prompting sequels to extend the narrative. Players are invested in what’s happening in El Paradiso Casino in As the Reels Turn, as new scenes open up payout possibilities.

Even though I-slots are innovative and earned Rival a place on the list of best US online casino software providers, the studio tends to stick to the classics.

It has a wide range of three-reel titles, designs with simple graphics, and limited pay lines. However, Rival is starting to embrace the latest in technology with Rival Alive.

Wrath of Medusa is the first Rival Alive game in US online casinos. It has a touch of the I-slots storyline but is based more on the special effects.

The game starts in a temple under siege and moves slowly into Medusa’s lair. A video intro welcomes you, and then you’ll experience features like expanding wilds and multiple bonus rounds. 

Here’s a sampling of the best games from Rival’s slot collections.

Rival Slot Category Standout Features
Wrath of Medusa Rival Alive 3D special effects, multiple bonus rounds, expanding wilds
Hole in Won I-slots Players take golf shots for extra prizes
Major Moolah Progressive jackpot Jackpot seeded at 10,000.00, interactive bonus round
Cosmic Quest: Mystery Planets Highest RTP Titles A 98.95% RTP, expanding wild worth 5,000 credits, X2 multipliers
Popping Pinatas Super Bonus Round Two bonus rounds including an interactive pick and win (Popping Pinata) game


betsoft logo
  • Year established: 2006
  • Location: Malta
  • Number of games: 150+
  • Highlights: SLOTS3, BetSoft to Go

BetSoft is considered to be one of the best software providers for Americans because of its cinematic-style slots.

The SLOTS3 collection features memorable characters like The Slotfather, The Exterminator, and Frankenslot’s Monster, accompanied by 3D special effects, video integration, and player interaction.

Take a look at some of the top SLOTS3 games available in US online casinos.

BetSoft Slot Setting the Scene Featuring
It Came from Venus! Farmer Skeeter protects his out of this world friend from the army Random multipliers and a “Feed Me” bonus round
Frankenslot’s Monster Dr. Frankenslot is in the laboratory with his new creation Flip the switch to make the monster come alive and grab some cash
The Exterminator The hard-working exterminator is on the Great Raccoon Chase Sticky wins and deciphering a blueprint for the raccoon’s location
The True Sheriff White hat versus black hats in a showdown in the wild west Bullets from the Sheriff’s revolver turn into wild symbols on the screen
2 Million BC Caveman versus Sabertooth on a quest for the diamond Collecting bounties for knocking out the Sabertooth and even more cash for the diamond

Instead of producing one game after another, BetSoft focuses on big productions. The studio boasts over 150 slots, but it’s more of a quality of quantity situation. Even the titles that don’t play out like a feature film provide at least one distinct feature.

Birds!, for example, features the feathery friends teetering on wires. The birds fly in and out of screen view, creating horizontal and vertical match-ups. Chain reactions keep the rounds active, as identical birds fly away, making room for more.

BetSoft is an award-winning slot developer, recognized for its mobile product line as well. One by one, BetSoft’s original games were converted to ToGo titles, and newer releases are mobile-first. The line-up available at real money casino apps includes the Slots3 collection.

Our top recommendation for playing BetSoft games online is Wild Casino.

Visionary iGaming

  • Year established: 2008
  • Location: Costa Rica
  • Number of games: Six live dealer table variations
  • Highlights: Shufflemaster camera, exclusive Blackjack variation

Visionary iGaming (aka ViG) is another software provider for US online casinos that doesn’t go over the top with quantity.

Instead, it focuses on providing some exclusive features to Americans who appreciate live dealer tables.

Here are some examples from Visionary iGaming’s live dealer table collection.

Game Highlights
Blackjack Pairs and Rummy side bets
American Roulette Picture in picture streaming with a close-up of the wheel
European Roulette Single zero game with the same picture in picture presentation as American Roulette
Baccarat and Super Six Commission and No Commission alternatives with Dragon and Pairs side bets
Early Payout Blackjack A ViG exclusive that allows players to avoid busting by taking a deal on a less than stellar hand

The Visionary iGaming difference involves the Shufflemaster system. Instead of using oversized cards, ViG sticks to standard decks in Shufflemaster machines. It also mounts two cameras in each one so that players get a view of the cards as they hit the table.

Every table is streamed in HD and offers a community chat option to give players the in-casino, social aspect of table gaming.

Visionary iGaming has turned into one of the best live dealer providers and is at the top of the list for US online casinos. Red Dog Casino is a great option for playing their games.

Other Software Providers for US Online Casinos

Rival, RealTime Gaming, and BetSoft are the big three for the best slots and RNG table software providers for US online casinos.

They dominate the virtual gambling market for Americans with hundreds of unique games developed for desktop and mobile access.

A few boutique studios also complete the picture, lending more variety and filling in the slot banks with a few exclusives.

Nucleus Gaming and Fresh Deck Studios

Nucleus Gaming would be number four on the list of the best US online casino software providers. It’s a bit bigger than a boutique studio with a 110-game collection that continuously expands.

You’ll find that Nucleus takes a similar approach to slots as BetSoft with its 3D cinematic-style games.  A few of the software provider’s top titles include Kraken Deep Wins, A Time to Win, and Spooktacular Spins.

Fresh Deck Studios is a live casino operator that takes a follow-up spot to Visionary iGaming. Like ViG, it doesn’t have a lengthy menu, but Fresh Deck offers Casino Hold ‘em, missing from the Visionary casino floor.


Americans have a relatively small number of online casinos and real money casino apps. This translates to an abbreviated list of the best software providers.

BetSoft, Rival, and RealTime Gaming have been producing slots and table games for decades and have vastly improved over time.

Each of the big three studios has embraced player demand and technological advancements to create memorable games that keep players coming back for more.

Players could still come across a few slot titles here and there from Magma (Konami) and other smaller studios. But RTG, Rival, and BetSoft still dominate the US online casino market with creative themes, unique features, and plenty of jackpot-driven games.

You’ll find their games at most of the best US online casinos.
