What Slot Site Operators Do

Slot site operators are the companies that run the websites and mobile apps on which you play your favourite games. Their role is to facilitate online gambling in a safe, secure and fair environment in line with UK regulation. The responsibilities of an operator encompass these areas.

  • Licensing – For a gambling operator to provide its services legally in the UK it must have a license issued by the UK Gambling Commission. Under the terms of their license the operator must follow strict guidelines that aim to prevent problem gambling or fraudulent activity on the part of the operator or the customer.
  • Games – establishing a game catalogue that offers a wide range of slots from different providers, made easily accessible via the website or app. Game lists range from a few hundred to 1,000s in size.
  • Payments – the operator provides secure payment services through a cashier to allow customers to deposit and withdraw funds to place bets with. Most operators accept debit cards, Paypal and a mix of other eWallets, pre-paid cards and mobile payment options.
  • Promotions – bonuses for players as incentives to sign up and keep returning are a big part of the online gambling industry. Operators create promotions that appeal to different customer groups based on their preferred games and typical spend levels. They usually comes in the form of free spins or deposit match bonuses.
  • Websites and Apps – the operator is usually responsible for building and hosting the websites and apps on which customers play the games. As well as being the access point to sign up, use the cashier and play the games, websites must include information like terms and conditions and promotions.
  • Customer Support – to assist players who may be experiencing technical problems with the website, cashier or games, understanding promotions or any other aspect of the service. Support for online casinos is typically available on live chat, phone or email. Some services are available 24/7 but most work from early morning to late evening.

White Label Operators

Under UK law an operator with its own gambling platform can sub-license their services to a 3rd party. In this partnership the operator providers the full range of gambling services whilst the 3rd party is the brand owner responsible for marketing the site to bring new customers in.

Sites like these are known as white labels, and the operators as white label operators. The configuration of their platforms and businesses is such that they can roll out new sites very quickly and easily, often with just a small adjustment to the colors and logos on their standard website template.

Popular white label operators in the UK include White Hat Gaming, Skill on Net and Aspire Global. They have 100s of slot sites between them. There are some useful upsides to playing at sites like these that anyone looking for a new slot site to play at might like to consider.

  • Familiarity – often each site from the same operator will have the same layout, game selection, payment options, bonus terms and support team. This is good if you want to play somewhere that you feel comfortable and at home with.
  • Licensed – all white label operators listed on this page have been issued with a UK license which means they are safe to play on. The UK regulator keeps a close eye on all licensees to ensure they stick to the strict standards that are set to keep gambling fair and avoid gambling related harms.
  • Big Game Lists – some white label operators have game lists to rival the big independent operators. For example, Skill on Net, who run over 50 UK gambling domains, have more than 7,000 slots on their platform. They are available on sites like Play OJO and Slots Magic.
  • Good Value Bonuses – white label operators often ‘network’ their promotions across all their sites to boost the amount of bonus money that they can give away. For example, a tournament that is open to players from 100 different sites can post a much larger prize pool than one that is only open to 1 small site.
  • Good Customer Support – operators with many white label sites to service will build a strong support team that is efficient and professional to maintain their reputation.
