Real Time Gaming (RTG) is an online slot provider with more than two decades of experience in the iGaming industry. Founded in 1998 in Atlanta, Georgia, the company was acquired by Hastings International – HBM Group in 2007 and moved its headquarters to Heredia, Costa Rica.
RTG was one of the first studios to offer multi-player poker and system-wide progressive jackpots. Their library now spans over 500 games including slots, tables and specialty titles, with new releases each month. The provider is especially known for the Real Series slots framework, networked progressive jackpots like Aztec’s Millions and Megasaur, and a Feature Guarantee Meter that ensures bonus triggers within a set number of spins.

RTG was founded in 1998 in Atlanta, Georgia, before being acquired by Hastings International – HBM Group in 2007. Following the acquisition, the company moved its headquarters to Heredia, Costa Rica, from where it has continued managing what’s become one of the biggest providers in the history of iGaming, with over 500 titles to their name.
In 2015, RTG introduced analytics software to help operators understand what players like based on real gaming inputs. The studio used that technology to shape newer releases, making them as appealing to players as possible. RTG history will not be complete without talking about their game library — since its establishment, the studio has continued to release high-quality titles across different themes and reel configurations.
While RTG wasn’t nominated for casino awards too often, their solutions were regularly appraised by operators and partner providers. The brand received positive feedback for its Multi-Channel Delivery platform, and RTG progressive jackpots have made headlines with over $82 million paid out to 6,660 winners across their networked titles.
RTG still strives toward innovation, which can be seen from its recent releases and tournaments which often include up to 10,000 players. FreeSlots99 gives you the chance to enjoy RTG free play and explore the brand’s releases without spending anything.
RTG mobile slots are developed using HTML5 technology — one of the pioneers of using this framework in casino gaming. HTML5 allows the provider to create titles that are optimized for PCs and mobile devices, with the same graphics quality and features across all screen sizes.
Since the launch of the HTML5 framework, Real Time Gaming has relaunched several of its earlier releases on the new platform. Latest advancements include guaranteed bonuses and turbo spins among the best examples of their mobile-first approach.
One of the questions new players often ask is which RTG titles they should try first. The RTG demo allows punters to explore different titles to see what makes it to their favorites list. Below are must-play slots across different themes and volatility levels — from Egyptian classics to dinosaur progressives.
Set during Cleopatra's reign in Ancient Egypt, this 25-payline progressive title delivers free spins, respins, wilds, and a multiplier bonus round. A classic from RTG's Real Series that has stood the test of time and remains one of the most played titles in their catalogue.
Set in ancient Greece following the heroic adventures of Achilles, this title features multipliers, free spins, wild symbols, and scatter symbols. The two separate free spins modes triggered by different symbols give players meaningful choices about how their bonus rounds play out.
A Halloween-themed title with ghosts and witches that combines gamble features, free spins, respins, and random wilds. The Witch's Brew bonus system keeps the experience unpredictable, making it one of the more entertaining themed slots in the RTG catalogue.
One of the titles that started it all for RTG — a Roman Empire-themed progressive with 20 paylines. Prizes are doubled during the bonus game, and scatter pays add extra value. A high max win cap of 40,000x makes this one of the more rewarding titles in the classic RTG range.
The Mayan civilization comes to life in one of RTG's most famous networked progressive jackpots. The total prize from the progressive jackpot often surpasses $1 million. Free spins bonus round and wild symbols round out a title that remains the benchmark for RTG's progressive jackpot offering.
Following a sneaky bank robber, this high-volatility title delivers one of the most generous free spins systems in the RTG catalogue — up to 390 free spins, a vault-cracking mini game, and a 23x multiplier. The highest RTP of the eight slots listed here makes it a strong choice for longer sessions.
Set on a volcanic beach inhabited by dinosaurs, T-Rex features wilds, free spins, and scatter symbols on a classic RTG reel layout. With the highest RTP in this group alongside Megasaur, it is one of the better-returning titles in the RTG catalogue for players who prioritize long-run value.
A Jurassic Park-style adventure with a networked progressive jackpot. The Megasaur feature is activated within 26 to 250 spins, giving players a guaranteed engagement window. Up to 10 free spins and wild symbols complete a package that shares the highest RTP in the group alongside T-Rex.
Now that we've covered the must-play titles from the provider, here are some additional highlights from the RTG catalogue worth exploring. Many players start with these releases and we'll pass down the main details of their best features:
There's no better place to start when it comes to RTG gaming options than Caesar's Empire. It's one of the titles that started it all as one of the initial progressive jackpot slots from the brand, offering 20 paylines and a very decent RTP of 97%. Plus, it has a free spins bonus with re-trigger potential if you're lucky enough to catch scatter symbols on the middle reels, making it an all-around pick for slot enthusiasts.
As yet another classic from the brand, we've got the Enchanted Garden title which was recently renewed for a sequel. Again, you've got a 20-pay line, a five-reeled title with a progressive feature, and a very decent, 97.5% RTP. We especially liked the introduction of the multiplier feature in the bonus round. So, when you trigger it, you can get all your prizes multiplied by x3 or even x5 if you land enough scatters.
With this next one, we're going back in time to Ancient Egypt to enjoy one of the classic slot themes with 25 paylines. Again, the bonus round features a multiplier prize, and that makes Cleopatra's Gold one of the best games you can try from this provider along with the previous two.
Although we love the combination of jackpot prizes and exciting free spin action, Mid-Life Crisis is nothing like the previous few slot games. Instead, it delivers nine paylines as a classic drop, offering a progressive jackpot and a layout worthy of the good-old Vegas casinos.
Besides those very exciting titles that we've mentioned, Realtime Gaming also excels in making some high-variance releases with massive payout potential. So, we thought it's only fair to give you a few recommendations in this category based on our firsthand playing experience.
All of these features an outstanding winning potential, and you can play free RTG slots online right here at FreeSlots99 to see what they're all about! Until then, we'll give you some pointers, starting with the Goblin's Treasure game, which has a twofold jackpot prize. You can win the Minor or the Major, depending on your bet size.
Other titles like Aztec's Millions include a modern layout with 25 paylines and, you've guessed it, a jackpot prize to spice things up a notch. Jackpot Pinatas also features a progressive prize, giving you a chance to win up to 50,000x of your bet size. The Shopping Spree slot has an old-school Vegas-esque appeal, so it's no wonder it got quite a few sequels from RTG studios.
As you can see by our overviews of Realtime Gaming slots, the company mainly prides itself on creating high-volatility progressive titles. So, it's obvious that the blazing jackpot feature is one of the key things to focus on here, but what about other gameplay mechanics?
We did some digging, and after exploring the features, graphics, and other key traits, we've concluded that these are the main advantages.
RTG never abandoned its philosophy of creating online casino games with a retro Vegas feel, and you can see that with every single spin. RTG was also one of the first studios to offer multi-player poker and system-wide progressive jackpots — milestones that helped shape the industry.
We would even argue that you wouldn't notice a difference between playing an old-school Vegas progressive slot machine at the Bellagio or Caesar's if someone gave you a phone with RTG's jackpot games instead. While we're at it, all of their options are mobile-first, so that lets you capture perfectly the retro vibe on your Android or iOS device.
Last but not least, we loved the re-trigger potential of their bonus rounds. You'll rarely find a casino software provider that lets you discover so many releases with a re-trigger feature to extend the bonuses. Plus, they don't place a cap on the number of times you can re-trigger the feature, and that's especially admirable.
Realtime Gaming, commonly referred to as RTG, is renowned for recreating the retro vibe that players loved about Vegas slot machines. The company was founded in 1998 and now has a library of over 500 games. The provider has gained fame for introducing modern features to classic slot games while maintaining the straightforward gameplay that makes RTG progressive jackpots so popular.
While numerous progressive jackpots offered by this provider are pooled, some online casinos offer games that do not contribute to the system-wide progressive jackpots. Therefore, it is always important to verify the status of every game with the casino before signing up. Also, stick with trusted casinos because several rogue online casinos have been spotted using RTG casino software.
A total of 6,660 people have won $82,898,249 in RTG progressive jackpots. The single biggest jackpot payout on RTG was on September 7, 2020, when one lucky punter won $5,467,358 while spinning on Shopping Spree.
Other popular RTG progressive jackpots include Aztec's Millions, Jackpot Pinatas and Megasaur. One thing that is obvious about this provider is that they prioritize gameplay, experience and features, all of which draw in and retain players who are not die-hard fans of retro titles.
