One of the top concerns for many online gamblers is that games provided by casinos are not fair. However, this is an unfounded concern as the laws in the UK surrounding online gambling, testing houses and fair gaming are incredibly strict. As long as you are playing at an online casino that is licensed and regulated by the UK Gambling Commission, you can be rest assured that all games offered have been randomly tested for their fairness and continue to be tested on an ongoing basis by some of the world’s top independent testing houses.

Carry on reading for all the information you need about testing houses, how they check games for their randomness and why the UK Gambling Commission only approves some testing houses.

What is the Role of Testing Agencies in Online Gambling?

The role of testing agencies in the online gambling industry is to ensure that all games from developers and operators are fair and random. These testing house companies work independently of casinos and so they cannot be influenced by any outside sources. One of the main jobs of testing houses is to check that the random number generator is working properly. This is done simply by spinning a game thousands of times and working out the statistical probability of winning. If a game does not meet these requirements, it will not be allowed to go live to online gamblers until it has been approved. This allows players to enjoy their favourite slots, casino and live casino games with the comfort that they are 100% fair.


Testing Agencies and the UK Gambling Commission

In the United Kingdom, the authority over the gambling industry is the UK Gambling Commission. Any testing house that wants to operate in this country to regulate and test gambling games for their fairness and integrity must be first be approved by this government body. There are strict rules around this process in the UK which is good news for players as it allows you to play at top UK casinos with complete peace of mind that they are being regulated by reputable testing houses. Furthermore, this helps to ensure the integrity of the online gambling industry as a whole.

UK casinos will usually advertise the testing house they are using with their logo on the casino homepage. This also signals to players that they are a reputable site to use. Gambling software developers and operators can choose from a wide range of testing house companies who are able to certify games for their fairness.

Before players get started playing at an online casino, it is always worth checking what testing house a casino uses as this is a clear indication of game fairness, proper UK licensing and regulation. If you discover a casino where no testing house badge is displayed, you can double check whether they are certified by visiting the official UK Gambling Commission website. Never make a deposit at any online casino where you can certify their credentials for legal operation in the UK.



All online casinos in the UK that are properly licensed and regulated by the UK Gambling Commission will have their games randomly tested. With so many fantastic testing houses to choose from, there is no excide for this not to be done and so you should never play at any online casino that does not carry this out.
