Inexperienced players are often concerned about fairness when joining a new online casino, and this uneasiness is perfectly natural, especially for first-timers. After all, they are entrusting casino operators with their hard-earned money, and fair play is the least they deserve in return.

Sometimes several losing rounds in succession are all it takes to convince rookies they are being cheated out of their money. The subject of today’s article is “Do online casinos really tamper with the games they offer?”, and the short answer is no, provided they are licensed and properly regulated.

Continue reading as we shed more light on the subject and explain how reputable online gambling businesses preserve the integrity of their games. The article also includes notable examples of rigged games from the past, along with tips on how to avoid gambling platforms that might cheat you out of your money.

Random Number Generators in Online Casino Games

Random Number GeneratorsAll online casino games run on random number generators (RNGs), which ensure their outcomes are completely arbitrary and fair to players. These algorithms churn out long and complex number sequences without discernible patterns, producing entirely random results in games that do not involve human dealers.

The RNG is constantly at work, never ceasing to produce arbitrary numbers that are transformed into different elements of casino games within a split second.

It determines what symbols will appear on the slot reels during a given spin, the values of the cards dealt in games like baccarat or blackjack, and the numbers the ball lands on in online roulette. Two types of random number generators are commonly used in online casinos:

Types of RNGs

1True Random Number Generators (TRNGs)

True Random Number Generators (TRNGs) rely on physical stochastic processes that are entirely unpredictable, such as atmospheric radio-frequency interference, electrical or thermal noise, and radioactive decay. Their number sequences are impossible to tamper with or predict because these physical phenomena are intrinsically random.

2Pseudo Random Number Generators (PRNGs)

Pseudo Random Number Generators (PRNGs) rely on complex computer algorithms to produce long sequences of numbers derived from shorter ones. The process of random number generation starts with an integer called a seed.

Although extremely difficult, it is theoretically possible for hackers or other malicious parties to decipher the PRNG’s entire algorithm if they discover the initial seed.

The likelihood of external PRNG attacks is minimal because gambling businesses implement numerous defensive strategies, including asymmetric cryptography, stream ciphers, advanced firewalls, and other security hardware.

Theoretical Return to Player (RTP)

Theoretical Return to Player (RTP)As random as their outcomes are, online casino games are programmed in a way that ensures the house always retains a small percentage of the overall amount of money wagered in the long term.

This percentage reflects the house edge and represents the casino’s long-term statistical advantage over gamblers. Gambling companies must turn a profit, after all, or else they would quickly go out of business.

On the other side of the coin is the theoretical return to player (RTP), which denotes the percentage of total wagers a game pays back to players as winnings. RTP can vary dramatically across different casino games, so here is an example with double-zero roulette.

RTP of American Roulette by NetEnt

1

This double-zero roulette variation has a theoretical return-to-player (RTP) of 94.74%.

2

NetEnt-powered casinos retain 5.26% of all money wagered on this game.

3

Players can expect to receive approximately $947 for every $1,000 wagered on American Roulette.

4

Gambling operators collect the remaining $53. Note that major software developers like NetEnt are also entitled to a share of the profits generated by their associated online casinos.

These percentages reflect the long-term profits. Some players may win big over the short term, while others may experience heart-wrenching losing streaks that could drain their entire bankrolls.

Players from the second category might be left with the impression the casino has cheated them out of their money by somehow rigging the game or reducing its theoretical return. In reality, experiencing such losing streaks is not unheard of when it comes to gambling.

Anything can happen over the short term with chance-based games like roulette or slots. Randomness and unpredictability are precisely what casino operators rely on. A truly unpredictable and therefore fair game will still return less money than the overall amounts wagered on it in the long run.

All casino games are statistically tilted to favor the house because of their rules and payout structures. Long-term losses are practically unavoidable for players, even if no one has tampered with the games.

Noteworthy Real Examples of Rigged Online Casino Games

Before we proceed further, we want to emphasize that rigorously regulated gambling sites would never consider offering rigged games to their patrons, as doing so would damage their reputation beyond repair.

There have been very few documented cases of rigged casino games, and they date back several years and involve gambling companies that operate in jurisdictions with lenient or nonexistent regulations.

The Role of Independent Testing Agencies

The Role of Independent Testing AgenciesAll reputable and properly licensed gambling sites submit their portfolios to regular audits to prove their games have not been tampered with and still meet their long-term theoretical expectations.

The audits are conducted by independent testing agencies approved by the regulatory bodies that license the gambling operators.

These third-party auditors inspect the random number generators that power the games to confirm there are no biases or glitches favoring a given casino, i.e., the results should always be randomly distributed.

Trusted operators publish the aggregate payout percentages of their entire catalogs, along with the average expected return for different gaming categories like slots, table games, and video poker.

We list some of the most highly accredited third-party testing agencies in the gambling industry below. You will have no reason for concern if your preferred online casino carries the stamp of approval from one of these independent auditors. The odds are most certainly above board.

  • Most testing houses have been officially approved by major gambling regulators like the UKGC, AGCC, DGE, AGCO, and Spelinspektionen.

The Role of Online Gambling Regulatory Authorities

The Role of Online Gambling Regulatory AuthoritiesOnline gambling regulators fulfill various essential tasks, including issuing licenses to approved gaming businesses, monitoring their operations for compliance with the rules, and safeguarding players from unethical practices. Before you sign up and deposit real money anywhere, always check which authority licenses and oversees the online casino you are interested in.

Playing at rigorously regulated gambling sites that undergo all the necessary software and payout inspections is the surest way to protect yourself against rigged games. Below, we list some of the most stringent regulatory organizations in the gambling industry.

Regulatory Organizations

1The UK Gambling Commission (UKGC)

The UK Gambling Commission (UKGC) regulates both land-based and online gambling in Great Britain under the provisions of the 2005 Gambling Act (soon to be revised). The regulator is incredibly strict regarding compliance and does not hesitate to suspend licenses or impose hefty fines on operators found in violation.

2Malta Gaming Authority (MGA)

Malta Gaming Authority (MGA) licenses are valid in many European countries, with a few exceptions such as Germany, the UK, Turkey, and France. Established in 2001, the MGA carries out various regulatory functions, including promoting responsible gambling, protecting player rights, and preserving the industry’s integrity through independent testing and audits.

3The Alderney Gambling Control Commission (AGCC)

The Alderney Gambling Control Commission (AGCC) oversees remote gambling businesses in Alderney. AGCC licensees can serve any market where it is legal to do so. AGCC-licensed operators that want to access certain markets, such as the UK, must also apply for permits from the relevant local regulators (the UKGC in this case).

4The Swedish Gambling Authority (Spelinspektionen)

The Swedish Gambling Authority (Spelinspektionen) grants licenses to trusted gambling operators that want to serve the Swedish market. All licensees undergo thorough verification and hold certificates confirming fair RNGs.

5The US Gambling Market

The US gambling market is regulated at both the federal and state levels. Each state that allows interactive gambling has its own watchdog responsible for compliance and fairness.

Notable regulatory bodies in the United States include the Pennsylvania Gaming Control Board (PGCB), the New Jersey Division of Gaming Enforcement (DGE), the New York State Gaming Commission (NYSGC), and the Nevada Gaming Control Board (NGCB).

6Canada

Canadian players seeking a secure, fair gaming environment should choose online gambling sites licensed by the relevant authorities in their province of residence.

These authorities include the Alcohol and Gaming Commission of Ontario (AGCO), the Gaming Policy and Enforcement Branch of British Columbia (GPEB), the Saskatchewan Liquor and Gaming Authority (SLGA), and the Alberta Gaming and Liquor Commission (AGLC), among others.

7Australia

Australia has adopted a framework similar to those in Canada and the United States, in which each state or territory has its own gambling regulator responsible for fairness and compliance. The Commission for Gambling Regulation oversees the industry in Victoria, the Office of Gaming Regulation controls gambling in Queensland, and so on.

Red Flags to Consider before Playing Casino Games for Real Money

Red Flags to ConsiderNow that we have established that all regulated operators undergo regular audits and would never risk their reputation by rigging their games, we will highlight several red flags to watch for before you join a real-money online casino.

A gambling site is not necessarily rigged if it meets one or two of these criteria. However, we still recommend that you exercise due diligence and take to your heels if you detect any suspicious anomalies in the games’ outcomes.

  • The online casino is blacklisted by numerous independent review sites.
  • Former customers systematically give negative feedback and complain about inconsistencies in results.
  • The online casino consistently receives low ratings from both players and professional reviewers.
  • Licensing information is obscure or altogether absent from the casino’s website.
  • The brand is licensed in a banana republic or a foreign jurisdiction with lax or no regulatory enforcement.
  • The casino never publishes the payout percentages of its games.
  • The operator’s name is associated with past cases of cheating and offering unfair games.
  • The operator insists its catalog is regularly audited but lacks a certificate from any recognized independent testing house.
  • Former customers consistently report delayed or altogether denied withdrawals.
  • The terms and conditions page contains unfair or ambiguous clauses open to broad interpretation.
