About Sister-Slots.co.uk

The team at Sister-Slots.co.uk is all about relevance and recency, meaning we not only review online slots but also ensure that we provide our readers with the most up-to-date information and put it into context.

Consider this: would a slot game with a high payout from ten years ago still be considered ‘high RTP’ today?

Reviewing a game and putting the information into context is crucial to providing players with transparent and unbiased information. Alongside this, we also ensure that screenshots or videos of the game are at most 12 months.

What are Sister Slots?

You might wonder about the term “Sister Slots”, a concept we pioneered this year. In a nutshell, Sister Slots are video slots that share the same provider. For example, Starburst and Gonzo’s Quest both belong to NetEnt, one of the industry’s most famous game developers. This is important information because it means both games have undergone the same quality assurance process before hitting the market.

The concept of relating brands by provider is not new and stems from the gambling industry. Most online casinos or bingo sites are not standalone websites but products that share the same environment, referred to as Sister Sites. The strategy benefits operators and players by allowing gambling firms to launch more brands faster. In contrast, players can be sure to receive similar quality across the full range of sites.

When it comes to online slots, the concept works similarly, which is why we put a special focus on it.
