What Happens If A Slot Machine Malfunctions?

Slot machines are one of the most well-known types of gambling games, both online and in land-based casinos. But like any technology, they can sometimes go wrong. 

This blog explains what can happen if a slot machine malfunctions, why it may occur, and what you can do if it does. 

If you’re new to gambling or just curious about how things work behind the scenes, this guide can help you understand how casinos in the UK are expected to handle these rare situations fairly and responsibly.


What Causes a Slot Machine To Malfunction?

Slot machines—whether online or physical—are built using technology that must meet specific standards set by the UK Gambling Commission (UKGC). These games are powered by computer software, and in the case of land-based machines, also physical hardware. Despite careful design and testing, faults can occasionally occur.

One common cause is a software glitch. All slot games rely on computer programmes to operate. These programmes include something called a Random Number Generator (RNG), which ensures the outcomes are based on chance. If this software experiences an error, it could lead to unusual results or stop the game from working properly.

For machines found in physical venues like casinos or gaming arcades, hardware problems can be the issue. This might involve damaged screens, broken buttons, or faulty coin acceptors. These machines also rely on electricity, so a sudden power cut could stop them unexpectedly.

Online slot games can also be affected by server downtime. This is when the platform hosting the game experiences issues, which may interrupt your session. In some cases, slow internet on the player’s side might cause delays or freezing, though that isn’t a fault of the casino itself.

What Happens When a Slot Machine Malfunctions?

When a slot machine malfunctions, the game may freeze, display an error message, or shut down completely. This can happen either during a spin or just after. While it can be frustrating, casinos—whether online or land-based—have processes to deal with this.

In a land-based setting, casino staff will usually examine the machine and report the fault. These machines keep a log of activity, so the casino can often see exactly what was happening when the fault occurred.

Online casinos store gameplay data securely. If a malfunction happens, the casino’s customer support team can check your game history. This allows them to identify where the issue may have occurred and decide the next steps.

UK-licensed casinos are expected to act fairly and follow rules set out by the UKGC. If the malfunction had an impact on your game, the operator should investigate. Depending on what they find, they might void the result or restore your game to the state it was in before the issue.

What Should You Do When a Slot Machine Malfunctions?

If you’re using a slot machine in a physical location and it stops working, the best step is to speak to a member of staff. They’re there to help and can raise the issue with the technical team. It can help to take note of what you saw on the screen, including any error messages or unusual game behaviour.

When playing online, use the casino’s customer support service. Most operators in the UK offer live chat or email assistance. Give them as much detail as you can, such as the name of the game, the time of the issue, and what happened.

You may also want to take a screenshot if possible. This can support your case if the operator needs to review your gameplay.

It can be helpful to understand the terms and conditions of each game before playing. These explain how the casino handles any potential malfunctions, along with your rights as a player.

Are Winnings Paid Out If a Slot Machine Malfunctions?

When a malfunction is confirmed, the outcome of the game may be declared invalid. That means any potential winnings linked to the error may not be paid out. This rule is typically included in the terms and conditions of UK casino sites.

Online and land-based casinos keep records of game results, and these logs are used to decide what happened. If you were due a win and the machine failed before paying it out, the casino might be able to verify it. However, if the fault changed the result of the game, the round may be cancelled.

All UK casinos must treat players fairly and resolve disputes in line with the Gambling Commission’s rules. The outcome must not benefit the casino unfairly.

Can Casinos Refuse To Pay Out?

In certain cases, yes. If a fault in the machine or software has affected the outcome of the game, the casino may choose not to pay any potential winnings from that round. This is only allowed when the malfunction is genuine and not caused by player behaviour.

That said, UK casinos can’t simply refuse to pay without reason. They are regulated by the UKGC, which requires fairness and transparency. Operators must explain why they’ve taken a particular action, and players have the right to dispute a decision if they believe it is unfair.

If a complaint cannot be resolved directly with the casino, you can raise it with an Alternative Dispute Resolution (ADR) provider. One example is the Independent Betting Adjudication Service (IBAS). This service is free to use for players and gives a final decision based on the facts.
