What Is the UKGC and Why Did They Implement the Slot Delay?

The UK Gambling Commission is the regulatory body responsible for overseeing the gambling industry in the UK. The commission introduced a 2.5-second delay on slot machines in October 2021 as part of its efforts to promote responsible gambling and protect vulnerable players. 

The concern about fast-spinning slot machines is that they increase the speed at which players can lose money, which can lead to financial difficulties, relationship problems, and mental health issues. This is especially true for vulnerable people that have a hard time controlling their gambling. 

According to this source, Neil McArthur, the chief executive of the Gambling Commission stated that evidence shows that certain features, including slots spinning quickly, increase the harm to consumers. While this statement sounds reasonable, we have found no supporting research for this.  

At the end of the day, implementing the delay was part of UKGC’s ongoing effort to reduce the harm from slot machines. The ambition was to help players maintain better control over their gambling habits and reduce the risk of developing a gambling addiction.

Consumer Responses: Mixed Opinions but Most Agree

When the UKGC proposes new rules and changes, the public is consulted. According to responses received in this particular matter, 65% of consumers agreed with the proposal to introduce a 2.5-second minimum spin speed to slot machines.  

However, several respondents raised concerns that the 2.5-second delay was insufficient and that a longer spin time should be considered to allow for the emotional and physiological arousal outcomes of the previous bet to subside. Suggestions of 3 seconds and 5 seconds were made.

On the other hand, some consumers stated that the proposed speed limit could have opposite effects on its purpose and result in longer play sessions, particularly to complete the wagering requirements of bonuses. Concerns were also raised that limiting the speed could spoil the player experience and lead to players increasing their stakes to compensate. 

It was also suggested by some of the respondents that this rule may have players seeking out unlicensed gambling sites that don't have the delay as opposed to playing on UKGC-licensed casinos. Thus, putting those players at a much greater risk of gambling-related harm. 

How Does the Delay Work?

The delay applies to all online and land-based slot machines in the UK, and operators are required to implement the delay as a standard feature on their games. The delay works by adding a 2.5-second interval between each spin, preventing players from placing bets faster than the limit. This means that slot machines take longer to play, leading to less money being wagered and potentially lost in a given period of time.

What Impact Has the Delay Had on the Gambling Industry?

Industry experts have expressed mixed reactions to the regulation. Some believe that the delay helps reduce harm from gambling and improve the industry's reputation. Others argue that it has a negative impact on innovation in the gambling sector because slots become less attractive to players and are given less attention by the industry as a result.

Naturally, casino operators have raised concerns about the delay leading to a reduction in revenue.

What Are the Pros and Cons of the Delay?

The pros of the delay are that it is likely to reduce gambling harm, protect vulnerable players, and improve the gambling industry's reputation. 

The cons are that it may have a negative impact on revenue and innovation in the gambling industry and that the slots are now less enjoyable to some players. The delay may also lead to a reduction in the number of slot machine games offered by operators if too many people stop playing them or reduce the time spent on them in favor of other gambling products.

What Have the Players’ Reactions to the Delay Been?

Players have shared their thoughts on the new regulation, with some welcoming the move while others feel frustrated by the limits it places on their ability to enjoy the game. The delay won't necessarily affect players' opportunities to win, but it does change the pace and rhythm of the game, which can be frustrating for some. For example, some players like to stop the reels quickly or spin them faster, which is no longer possible with the delay in place. 


Overall, the UKGC's delay on slot machines has been viewed as a positive step towards responsible gambling and harm reduction. While there may be some impacts on revenue and innovation, the long-term benefits of the regulation are likely to outweigh the costs. With more effective regulations and responsible gambling measures, the UK gambling industry can continue to thrive while ensuring the safety and well-being of its customers.
