The Home of Online Slot Reviews

Welcome to Online Slot Master – a brand new site written by me, Scott Daniels to bring you authentic slot reviews wherever you are in the world! I’ve  been playing land-based and online slots since 2004, and it’s fair to say I know a thing or two about them. I can give you objective opinions on which are the best to play, as well as which slots you should avoid!

You won’t find hundreds of reviews here yet, because, unlike countless other websites, Online Slot Master isn’t a company and I don’t have a team of writers! That’s how you can be sure you’re getting honest reviews as opposed to mass-produced rubbish purely aimed at getting you to click affiliate links. You can read more about my reviews in the ‘About’ section, and learn why Online Slot Master is different from the rest.

Latest Reviews

I’m building the review collection as quickly as I can, and now feature online slot reviews from the biggest providers such as Microgaming, NetENT, Big Time Gaming, Novomatic, Pragmatic Play, and Play N’ Go. You’ll find a great choice in the slot review section.

No Nonsense Slot Reviews

If you’re new to Online Slot Master, you will have noticed that I don’t yet have thousands of reviews. That’s because my reviews are authentic and based on my own experience. If I haven’t played a slot for a while, it will take time to play it with my review head on so I can refresh my memory of all the good and bad points! I focus on creating content that’s actually useful rather than creating enticing reviews just for the sake of clicks.

My recent review of Lil’ Devil proves the point. It’s actually a really popular slot that gets a lot of love, but I was left quite underwhelmed! If you’re serious about researching slot reviews before you play, then I guarantee you’ve come to the right place for genuine information.

Best Casinos for Online Slots

The best online casinos will have something for everyone, no matter if you’re new to slots, or a veteran player. Each one of the featured casinos is fully licensed, and each is regulated by the UK Gambling Commission, so you can be sure you’re playing safely. I take safety and privacy very seriously, which is why I will never show links to any online casino that doesn’t have a robust responsible gambling policy. I have played at all the brands I feature, and there will be pros and cons to each of them depending on what you’re looking for. However, none of the featured casinos will compromise your safety, security and deposits. So take your pick and enjoy your experience!

How I Create My Reviews

I’m putting a lot of effort into creating my slot reviews, but that means I get to spend a lot of time playing! However, I know that no matter which slot you play, your experience will be based largely on how much you win or lose. I have therefore decided to focus my reviews on the experience rather than being swayed by personal wins or losses. I’ve broken the review down into 4 distinct areas:

Theme

All online slots have a visual theme and whilst many are based on actual TV shows, or films, there are so many more that have an entirely original concept. The slot reviews look at the theme, graphics and animation to gain an overall sense of how visually entertaining the game is.

Soundtrack

A large part of your experience whilst playing a slot will be based on the incidental sounds for wins etc or the soundtrack that sits behind normal or bonus gameplay. The sounds you hear whilst playing are an integral part of the entertainment, so my online slot reviews look at whether they add to the overall experience and if that’s a positive thing.

Gameplay

Here I look at the overall gameplay of the slot. An online slot with high volatility is unlikely to produce wins as much as one with low volatility during the time you play. The question with any game though is whether the wins are sufficient enough to keep your attention and keep you entertained. That’s why my slot reviews look at the speed of play, and the slickness of the slot. I also take a look at some of the additional features to the slot and whether they improve the overall experience.

Entertainment Value

Here, I have combined all of the elements examined so far to reveal the overall entertainment value of the slot. This takes into account my personal experience and enjoyment regardless of wins or losses. Is the slot likely to leave you wanting more, or will you never return? You can find out what I thought without spending a penny.

The Overall Rating

Each of the examined elements is given a percentage score. The overall rating is simply an average of all the elements which should give you the heads up of what you can expect.

Hall of Fame

Each month, I’ll be looking over my slot reviews, and awarding them a place in our Hall of Fame. Taking the top spot this month is Big Bass Bonanza. It’s simple, relaxing, and extremely entertaining to play. In my case it was profitable too. Read the review below to learn why Big Bass Bonanza came out top this month!

Hall of Shame

You can’t really have a Hall of Fame without having a Hall of Shame! That’s why, every month I’ll be revealing which online slot deserves its place on the naughty step. Whether it’s a poor theme, an annoying soundtrack, or gameplay that just sends you to sleep, I’ll be sure to let you know! This month’s award goes to Lil Devil, and you can find out why in my review below.
