From RNGs to AI: Five Technologies That Changed Gambling

The future of gambling will be defined by technology, according to senior leaders across some of the industry's largest B2B gaming companies.

Paolo Personeni, Managing Director of Managed Betting Services at Sportradar, told iGaming Business in 2022 that gambling operators were automating more of their businesses and relying on increasingly sophisticated data systems. A few years later, the conversation has changed remarkably little. Executives at LuckyStreak, BetGames, Live88, and Vindral continue to point to advances in live streaming, automation, and real-time infrastructure as the technologies driving gambling's next chapter.

This article looks back at the innovations that fundamentally transformed gambling — technologies without which today's industry simply wouldn't exist in its current form. Others redefined the gambling experience and laid the foundation for the industry's next chapter.

1. Random Number Generators (RNG)

Random Number Generators (RNGs) have come a long way—thousands of years, in fact. Humans relied on physical methods like dice and coin flips, mainly for games of chance. The first computer-based RNGs emerged in the late 1940s to support scientific computing and simulations. Then, by the mid-1990s, they had become the engine behind the first real money online casinos.

Their ability to generate statistically random, unpredictable outcomes in milliseconds made it possible to recreate casino staples, from slots and roulette to blackjack, video poker, and even modern crash gambling games, entirely in software. As the industry grew, regulators introduced strict testing standards. Third-party companies like eCogra and iTech Labs now run millions of simulated rounds to make sure RNGs aren't being tampered with and that every game works exactly as advertised. 

2. Provably Fair Technology

But RNGs aren't the end of the story. Because, see, gambling online the traditional way means trusting three things: the casino, its RNG, and the independent auditor who certified it. Provably fair games, such as Stake's Originals and many third-party titles now available on Stake.US, change that by letting you verify every single outcome yourself.

Here’s how provably fair technology works:

1. Before you place a bet, the casino picks a random value (server seed) that will be used to help determine the result. Instead of revealing it right away—which would essentially reveal the outcome—it gives you a cryptographic "fingerprint" of that value, called a hash. 
2. Next, the game feeds the server seed into a publicly documented algorithm, along with a random value you or the casino generates (the client seed) and a counter that increases with every bet (the nonce), to calculate the round's outcome.
3. Once the round ends, the casino reveals the original server seed. You can enter it, along with the client seed and nonce, into the platform’s built-in verifier—or any other third-party tool—which recalculates the outcome and confirms it matches the result.

3. Live Dealer Streaming Technology

Live dealer streaming as a concept came about once video streaming, online casino software, and broadband internet had all matured to the point where bringing them together seemed somewhat possible. Playtech made the first real commercial breakthrough in 2003, and at roughly the same time, CWC Gaming launched CasinoWebCam, broadcasting real dealers from a studio in San José to players over the internet.

Rather than inventing something entirely new, I like to think of live dealer casinos as a bridge between the physical and virtual sides of gambling. Suddenly, you could watch professional dealers shuffle cards and spin roulette wheels while placing bets exactly as it happens on physical tables. It also brought the possibility for users to interact with one another through built-in live chat systems. 

4. Geolocation

Geolocation solved one of online gambling's biggest regulatory hurdles by allowing operators to verify a player's physical location using a combination of GPS, Wi-Fi signals, IP addresses, Bluetooth, and cell tower data. This is important because, in the US, gambling laws are based on where you're actually standing, not where you live.

In practice, it largely happens behind the scenes. At most, you'll see a pop-up appear on desktop asking to share your browser's location before play can begin. Casino mobile apps typically handle the process automatically once access has been enabled. If the software can't verify where you are — or detects signs that you're masking your location, such as through VPNs or proxies — it'll block access. 

5. Artificial Intelligence (AI)

These days, you see artificial intelligence just about everywhere in online gambling. The table below highlights a few examples. 

➡️ Did you know? Several sports bettors are embracing AI as another tool to help inform their picks.

Sportradar Chief AI Officer Behshad Behzadi also explains how generative AI is being used on the customer-facing side to explain odds and statistics in plain language. You can already see this across many sports betting sites, where AI surfaces key trends from previous matchups and player performance alongside the markets available.

Where gambling technology goes from here

Every technology covered here, be it RNGs or geolocation, earned its place for a different reason. Many solved problems the industry simply couldn't move forward without. Others, like live dealer streaming, built on what was already there and made the experience better. AI seems to be following the same path, only at a much faster pace. Every few months, another use case seems to emerge somewhere in the gambling ecosystem.

And that's probably how it'll keep going. The gambling industry has a habit of taking technologies once they become good enough and finding new ways to apply them. Whether that's VR tables, AI dealers, or something nobody's talking about yet, the next breakthrough will likely follow the same playbook.
