Who Owns Prime Slots?
Prime Slots are owned and operated by SkillOnNet (UKGC: 39326), which is a company that boasts a significant number of domains on its licence.
Its licence has been in place since 2014, giving it over 10 years' worth of experience in the market. With a blend of being a modern-mover and an experienced player, it should be capable of delivering a strong gaming platform.
It is easy to think that way. Here, our look at the Prime Slots' sister sites will delve into just how well SkillOnNet delivers it.
What Are the Prime Slots Pros and Cons?
If you are someone that wants your casino of choice to standout as the "in" choice when a friend looks over your shoulder, Prime Slots is not for you.
The design of the site is very square, very block orientated and, ultimately, looks a bit dated in the way it presents itself.
Despite those design flaws, there are lots of good things about the site too. One of them being that the navigation and user interface all works seamlessly. Menus enable expandable and collapsible options to keep things clean.
That all largely flows into the game lobby too. The squared edges of each game tile and category header are quite abrasive on the eye, but each section and title are spaced well, which means there is zero trouble interacting with the game of your choice.
The choice of games is a noteworthy topic too. Prime Slots possesses around 6,000 games in total, and it is far from all slots.
For example, there are in excess of 300 blackjack variations alone. It's an above average game haul, by a reasonable distance too. It does lose a mark in our review, however, for the absence of an in-depth filtering tool.
Prime Slots Sister Sites Reviewed
Prime Slots is not the prettiest site you're ever going to see, but it works well and boasts a good range of games. Are there Prime Slots sister sites that offer a more rounded platform?
Slingo
The first Prime Slots sister site we look at is Slingo, and there are real similarities between the two brands, especially in overall design.
There are some differences, particularly with the menu layout, but the game lobby at Slingo is displayed with the same sharp lines and category separators. It makes the look and feel very familiar.
We have called out the fact that the two sites aren't complete clones, though. One big factor that is favourable at Slingo is the collection of games.
There are in excess of 8,000 games on offer there. It's a deep pool by any measure, and is further boosted by the presence of a bingo section. That is another point of distinction for Prime Slots.
There are shared shortcomings in the game filtering but, to be fair, you don't get that with Prime Slots either.
With all things considered, you'd have to give the slight edge to Slingo, with the extra games being the key factor.
BacanaPlay
BacanaPlay is certainly a brand that punches you in the face when first landing on it. The bold orange header isn't the most beautiful of designs but the overall design is an improvement over what you get at Prime Slots.
Those design improvements really come to life in the game lobby. Tiles are slightly larger, navigation between them is a bit smoother and the ability to search and filter games is a big step ahead.
The game filtering options at Bacana sees users able to target games by provider, min and max bets, game volatility and more.
With two notable wins compared to Prime Slots, it is important to point out that it isn't better across the board.
The number of games on offer at BacanaPlay - which is a big deal for most casino players - is considerably lighter.
You still have big name providers delivering games and the library isn't pathetic by any stretch, however, you're looking at around 2,200 games in total - not 6,000.
PlayOJO
When you are looking at Prime Slots' sister sites, it is hard to look any further than PlayOJO. All the design flaws we've called out on other sites during this article are nowhere to be seen and, just generally, the overarching design and manoeuvrability of PlayOJO is very good.
There is a bold colour scheme at play once again but, for our money, it really works here, with the smart looking icons giving the bulk of the colour pop. That slick design runs into the physical interaction too, with intuitive scrollbars used to get around the site.
With close to 9,000 games on offer, and a good filtering tool as well, it is fair to say that PlayOJO offers you everything that Prime Slots does - and a whole lot more.
