The need for independent casino testing did not exist in 1970. Gambling was illegal in most places, or severely restricted. The few casinos that operated in Nevada were run by regulated commissions and trusted to police themselves. There were no third-party auditors. There was no need.
This began to change in the 1990s when online gambling emerged. The first online casinos launched in 1996. They operated from offshore jurisdictions with minimal oversight. Players had no way to know if the games were fair. A software provider could program an RNG that favored the house. A player would never know.
The Problem and the Solution
Regulators understood quickly that something had to change. If gambling was going to be legal and legitimate, there needed to be proof that the games worked as advertised. Proof that the random number generators were actually random. Proof that payout percentages were accurate.
Two organizations emerged to fill this gap: International Game Technology Labs, which became iTech Labs, and Gaming Laboratories International, known as GLI. Both began in the late 1990s. Both saw the same problem and the same opportunity.
GLI was founded in 1998. The company based itself in Newark, Delaware, far from the bright lights of Las Vegas. It was intentional. Independence meant physical and organizational distance from the industry it was testing.
iTech Labs emerged slightly later. The company established offices in Brisbane, Australia. It would eventually become the testing agency for many Asian jurisdictions, as online gambling began to expand through that region.
How Testing Works
The testing process is methodical. A casino software provider submits their game code to a testing agency. The agency does not take the provider's word that the code is fair. They run it.
They verify the RNG using mathematical analysis. They test that sequences of random numbers conform to statistical distributions. They run millions of draws to check for patterns. Any pattern suggests a bias or flaw in the generator.
They test the payout percentages by running simulations. A slot machine that advertises a 96 percent RTP (return to player) is tested by running millions of spins. The actual payout percentage must match the advertised percentage within a narrow tolerance.
They test every feature. Every bonus round. Every scatter symbol. Every multiplier. Everything gets audited.
The Regulatory Framework
Once a game passes testing, the testing agency issues a certification. This certification means that the game has been tested by independent experts and found to be fair. But certification alone means nothing without regulatory backing.
The Malta Gaming Authority recognized iTech Labs and GLI certifications. So did the UK Gambling Commission. The Nevada Gaming Control Board, though it regulated physical casinos where testing was handled differently, came to respect these agencies' work.
Regulators began writing this into licensing requirements. If you wanted to operate a licensed casino in Malta, you needed to use tested software. If your software was certified by iTech Labs or GLI, that was acceptable. This created a powerful incentive for software providers to get certified.
The Industry Impact
By 2010, testing had become standard practice. Major software providers like NetEnt, Microgaming, and Playtech all submitted their games to these agencies. The cost of testing was built into the software development budget.
This had a dual effect. It meant that legitimate casinos could advertise certified games, building player trust. It also meant that bad actors could not compete on equal terms. Running an illegal unregulated casino without certified games became a signal of predatory intent.
The testing agencies expanded their scope. They began testing live casino streams. They tested payment systems. They tested security protocols. They became the technical gatekeepers of regulated gambling.
The Standards Question
One issue that emerged was the question of which agency's certification to trust. Both iTech Labs and GLI had strong reputations, but they operated under different standards. A game that passed one agency's tests might have different specifications from another agency.
This led to harmonization efforts. Industry groups worked to standardize what fair testing meant. The eCOGRA standard emerged as a third-party certification that attempted to bridge these gaps.
But power concentrated with the testing agencies. If a regulator demanded iTech Labs certification, a software provider had to go to iTech Labs. This was not monopolistic, exactly. There were other testing agencies. But the major ones dominated.
The Present
Today, independent testing is standard practice. Any legitimate casino uses tested software. Players can generally trust that the games work as advertised, assuming they play at a regulated casino using certified software.
Unlicensed casinos still exist. They do not use certified games. They do not have independent audits. This is now a standard warning sign. A casino that refuses to use tested software is a casino to avoid.
The testing agencies have become so embedded in the regulated gambling industry that their role is often invisible. Players see the certification on the website and move on. But behind every certified game is months of work by engineers at iTech Labs or GLI, ensuring that the randomness is real and the payouts are honest.
This did not happen automatically. It happened because regulators demanded it and software providers accepted it. The testing agencies simply provided the infrastructure. But that infrastructure has held up for more than two decades.
