Online Casino Software

After the online casino market shifted in 2006, many of the major software providers in the industry – firms like Microgaming, Cryptologic, and Playtech – directed their client casinos to restrict access to real money gaming for American players.

Fortunately for the millions of online casino enthusiasts living in the US, a number of positive developments have removed previous stigmas associated with the industry. In December of 2011, for example, the Justice Department issued a revised interpretation of the 1961 Wire Act, ruling that this longstanding law applies only to sports betting over the internet, and not gambling on casino games or poker. Furthermore, Nevada, New Jersey, and Delaware have recently legalized online casino software and gambling, with California, New York, and Illinois currently considering similar legislation.

Developers Design For US Casino Market

Accepts USA Players iconSeveral designers and developers of casino software online maintained a presence within the American marketplace, likely anticipating that federal legal opinion would shift toward regulation rather than prohibition. Companies like Realtime Gaming (RTG), Rival Gaming, Top Game Technology, and WGS Technology continue to serve customers in the U.S., providing superior software services for a number of leading online casino platforms.

If you’ve played recently on Bovada, Club World Casinos, Lincoln Casino,, or Uptown Aces, the experience was powered by one of the four online casino software companies listed above. With dozens of online casino software platforms and brands accepting US customers – but only four software providers breathing life into the gameplay, graphics, and interface – even experienced players can have trouble navigating the crowded marketplace.

Know Which Online Casino to Play At

Many online casinos share similar words or phrases, and even though several sites may be affiliated with the same software provider, each can have its own distinct reputation and standing within the industry. Knowing which online casino software to avoid is half the battle for players these days, and unfortunately, even reputable software companies can have their products taken advantage of by unscrupulous operators.

To help players identify the crucial differences between each of the four primary casino software providers serving US customers, we’ve compiled detailed reviews for each company. This page serves as an introduction to each software firm and includes links to the main review pages.

Realtime Gaming (RTG)

realtime gaming softwareAs a major player in the online gambling space since 2006, Realtime Gaming or RTG has developed into one of the industry’s primary players.

The company is known for creating world-class online casino software. Giving the best experiences, developing proprietary games, and powering the software engines behind many of the world’s most popular platforms. You’ll find dozens of RTG casinos, and while most offer the standard package of game options, many sites like Slotastic and Slots Plus specialize in specific segments.

Casino Customization

Known for a willingness to allow its client casinos full operational freedom, RTG doesn’t meddle in management, so the platform’s operators are free to customize certain configurations. Coin denominations, wager amounts, and the number of decks are all common adjustments found among RTG casinos. Players appreciate this level of variability, because unlike competing companies, RTG is able to provide a different gameplay experience across its various client casino brands.

Extensive Game Variety

rtg-game-varietyAnother selling point of RTG casino software is the sheer variety of game selection. The company takes great pride in developing the most expansive menu of virtual casino games in the industry. Players will find the classics, but games like blackjack, baccarat, craps, roulette, and video poker are also augmented by several different variations. With options like Match Play 21, Super 21, American roulette, European roulette, Aces and Eights, and Jacks or Better, each of the main casino games has been adapted by RTG to match regional rules, common variations, and other differences players expect to find in brick and mortar casinos.

All-Around Gaming Experience

The result is a full-fledged casino experience accessible directly through your laptop, desktop, or mobile computing device. Relatively new additions to the casino floor, such as the hybrid table games Casino War, Let ‘Em Ride, Pai Gow Poker, and the Caribbean trio, can all be found on RTG casino platforms. In fact, many of these action-packed player favorites can be played only through RTG software.

More About RTG

As you’ll discover by reading the main review page, RTG’s willingness to allow client casinos to control their own operations has led to occasional instances of “rogue actors” taking advantage of players. Fortunately, we’ve compiled a lengthy list of reputable RTG casinos which have taken care to provide quality customer service. RTG has earned the status of recognized industry leader, and a few rogue actors aside, the company’s lineup of client casinos and gaming options is unmatched.

Rival Gaming

rival gaming softwareThe appropriately named Rival Gaming was founded in 2006, immediately providing the main competitor to Realtime Gaming’s soon to be dominant position within the U.S. market.

World-class design forms the foundation of the company’s software specialization, and Rival casinos offer more than 100 unique virtual slot titles. Along with classic themes like Blazin’ Buffalo and Cleopatra’s Coins, Rival Gaming is home to the revolutionary iSlot concept.

Popular iSlots Games

Cosmic Quest 1 Mission ControlWith its continually expanding menu of iSlot titles, Rival Gaming immerses players in a full-fledged storytelling experience, offering interactive gameplay along with traditional slot machine elements. Games like Cosmic Quest: Mission Contol and the As the Reels Turn series create the illusion of playing role-playing games (RPGs), which have become quite popular during the last decade. The combination of RPG storytelling and casino gambling is a novel approach, and Rival Gaming’s iSlot concept is unique.

Look Deeper Into Rival

The main review page contains a detailed rundown on all of the games and variations included in Rival client casinos. Players searching for an alternative to Realtime Gaming’s particular brand of online casino software usually find themselves playing at a Rival casino. It offers one of the largest portfolios of client casinos and key software differences.

 Pragmatic Play

pragmatic play logoThe company known today as Pragmatic Play, was formerly TopGame Technology, emerged from the chaotic days following the federal government’s 2006 shakeup of online gambling.

As was the case with other online casino software providers at the time. It didn’t take long before online casinos affiliated with Top Game Technology software began taking advantage of the unregulated marketplace. Sites like Rome Casino and Rich Casino refused to pay out jackpot winners, manipulated reels on slot machines and provided spotty customer service when complaints inevitably arose.

Check for Blacklisted Casinos

Caution iconRather than deal with this situation by severing ties with the offending casinos, TopGame Technology elected to continue doing business with several rogue actors. You’ll have to check out the Pragmatic Play review page to find a full list of “blacklisted” Top Game casinos, but several sites have sullied the company’s reputation among players and industry watchdogs.

With so many reputable options out there working hard to ensure online casino fans in the U.S. can still enjoy their favorite games through Pragmatic Play, companies like the former Top Game Technology and its affiliate casinos should be avoided at all costs. Do not spend a single penny on one of these sites, taking some time to learn how rogue casinos operate.

WGS Technology

wgs technology softwareAs online gambling operations came and went, the casino software developer known today as WGS Technology previously did business as the Canadian firm OddsOn in the 1990s and 2000s, before becoming Vegas Technology in 2005.

WGS Technology emerged from the wreckage of the now defunct Vegas Technology, but at one time the company powered many well-known online casino brands in the U.S. Also known as Wager Gaming, the company serves a small fleet of just five online casino software platforms, currently running a skin of the same software used by previous Vegas Technology properties like English Harbour and Golden Vegas.

Despite the limited number of client casinos, WGS Technology has developed the closest thing to Realtime Gaming’s comprehensive casino game menu. You won’t find every one of the table games, and specialty games, but for the most part, WGS casinos manage to include the widest variety short of the RTG brand.

Games Selection Expanded

Hot DiceThe selection is expanded further by WGS Technology’s signature specialty games. Dazzling Dice and Hot Dice, which blend elements of video poker and craps to create a fun new gaming experience, can be found only on sites utilizing WGS Technology’s software suite. Poker Slots, another proprietary game from WGS, combines the best of slot machines and video poker, and while these games may not offer the best house edges around, players always like experiencing the thrill of something new.

Fans of online slot machines will enjoy an expanded menu of more than 100 virtual slot machine titles. The games are usually knockoffs of more established themes and titles, but when it comes to the actual gameplay and prizes, WGS creates faithful reproductions across the board.

Casino Software Providers Serving the US

Comparing online casino softwareIn addition to the four main casino software online providers covered above and on the main review pages, a few smaller software providers make their services available to American players.

Companies like Betsoft, 888 Casino, and America’s Card Room have each attempted to make headway by catering to specific segments of the overall casino gambling market.

Betsoft specializes in cutting edge, high-powered 3d video slot machine games while America’s Card Room offers predominately poker-oriented games, but both sites also include full casino game software suites.
