Before you can gamble at an online casino, you need to create an account. But each player is only allowed to set up one account per site — you must not open any more.
Why do casino operators have this rule in place? And what can they do to penalise players found violating it?
You’ll find out why in this post. Read on to learn:
- Four reasons why you can’t open multiple casino accounts in the UK.
- Why players may create more than one account at an online casino.
- How casino operators deal with players they suspect of multi-accounting.
Four Reasons Why You’re Not Allowed More Than One Casino
Here are the top four reasons why online casinos don’t allow more than one account:
Multiple Accounts Could Indicate Bonus Abuse
Online casinos offer a variety of promotions to attract players and boost engagement. One of the most popular examples is the welcome bonus, which gives players a deposit match, free spins, or another perk. Each member is only allowed to take advantage of a welcome bonus and most other promotions once.
But in some cases, players try to cheat operators by setting up two or more accounts (known as multi-accounting). They use these different accounts to sign up for the same bonus again and again. Using this technique, members may claim a 100% deposit match several times or grab hundreds of free spins for slots.
Yet while bonus abuse is a common issue, companies in the UK iGaming industry have various tools and techniques to catch perpetrators out. This includes analysing information to spot:
- Similar patterns of use
- Shared internet protocol (IP) addresses
- Matching bank details
- Identical addresses
As bonus abuse can be a costly problem for casinos, operators won’t hesitate to penalise any users they suspect of multi-accounting.
Identity Thieves May Use Multiple Accounts
Fraudsters may use stolen information to set up multiple accounts at an online casino. They will use other people’s payment methods without authorisation to fund their gambling, and they may also participate in bonus abuse. Identity theft could be connected to other criminal activities, such as money laundering.
But as with physical casino venues, online casinos have strict rules around proof of identity. The Gambling Commission of Great Britain requires operators to perform comprehensive identity checks to root out fraudsters.
Members must upload various documents to credibly verify that they are who they claim to be. You will be asked to upload a copy of your:
- Driving licence
- Passport
- Utility bills
- Official ID
Operators will only allow you to gamble after verifying your identity. This process can prevent users from creating accounts with stolen information.
Players with Two or More Accounts May Manipulate Games
Players may open two or more accounts at an online casino to manipulate games.
For example, a perpetrator could take part in a live casino game via two accounts at the same time. This would let them use a technique such as chip dumping to give themselves an unfair advantage and potentially influence the outcome of a game.
Additionally, a player may simply use multi-accounting to experiment with different strategies without affecting their main account. While this isn’t an attempt to manipulate games, it still involves deceiving operators.
Gamblers May Put Themselves at Risk By Using Multiple Accounts
According to the Gambling Commission, all licensed casino operators in the UK must provide players with information on responsible gaming. This is vital to encourage safe play and prevent vulnerable individuals from gambling-related harm.
Additionally, people who struggle to gamble in a responsible way can use self-exclusion and other services or tools to prevent access to their casino account. These are available on mobile and desktop sites.
Unfortunately, some individuals may set up multiple accounts to bypass these measures and continue gambling. But operators can help these users regain control by identifying and terminating linked accounts.
How Online Casino Operators Handle Players with Multiple Accounts
If a casino operator suspects any member of having two or more accounts at the same site, it will investigate the matter to gather evidence. But during that process, they will suspend all accounts involved to prevent the user(s) from gambling in any capacity.
In some cases, an operator might discover that a player’s activities justify account termination. They will close all of the user’s accounts and may report them to the police if legally required to do so.
If a casino has sufficient evidence of multi-accounting, they will void and cancel all winnings generated. Any money spent from deposits will not be refunded.
Even creating multiple accounts as a genuine mistake can lead to the same results. That’s why it’s always best to check whether you have already registered with a casino before signing up.
Conclusion
Online casinos prohibit users from opening multiple accounts to prevent bonus abuse, game manipulation, and other common issues. If an operator suspects you of multi-accounting, your accounts will be suspended or even terminated.
