The Home of Online Slot Reviews
We are Online Slot Master- the home of online slot reviews. Our brand new website is written by online slot lovers for online slot lovers! We are a small team, and each of us love the thrill of playing slots online. I have personally been playing since around 2004.
Our aim is to provide genuine reviews of as many slots games as possible, so you know what’s worth playing before you spend your money. We’ll tell you everything you need to know, and we’ll even tell you which slots to avoid. You can even get in touch and request reviews using our contact form, and we’ll get right on it!
You can find more information about us, and all the information on on how we rate slots is below. So with all that said, it’s time to crack on and bring you all you need to know about playing online slots!

We are rapidly building our review collection, and feature online slot reviews from the biggest providers such as Microgaming, NetENT, Novomatic, Big Time Gaming, Novomatic, Pragmatic Play, and Play N’ Go. You’ll find a great choice in our slot review section.

No Nonsense Slot Reviews
If you’re new to Online Slot Master, you will have noticed that we don’t yet have thousands of reviews. That’s because our reviews are authentic and based on actual player experience. If we haven’t played a slot for a while, it will take time to play it with our review heads on so we can refresh our memories of all the good and bad points! We focus on creating content that’s actually useful rather than creating enticing reviews just for the sake of clicks.
Our recent review of Lil’ Devil proves the point. It’s actually a really popular slot which gets a lot of promotion, but we were left quite underwhelmed! If you’re serious about researching slot reviews before you play, then we guarantee you’ve come to the right place for genuine information.

How We Create Our Online Slot Reviews
At Online Slot Master, we put a lot of effort into creating our slot reviews. That means we get to spend a lot of time playing. We are genuine slot players who just love to play! However, we know that no matter which slot you play, your experience will be based largely on how much you win or lose. You can win or lose lots on any slot, so we focus on the experience rather than being swayed by personal wins or losses. We break 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. Our online slot reviews look at the theme, graphics and animation to gain an overall sense of how visually entertaining the slot 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 our online slot reviews look at whether they add to the overall experience and if that’s a positive thing.
Gameplay
Here we look at the overall gameplay of the slot. An online slot with a high volatility is unlikely to produce wins as much as one with low volatility during the time you play. The question with any slot though is whether the wins are sufficient enough to keep your attention and keep you entertained. That’s why our online slot reviews look at the speed of play, and the slickness of the slot. We examine some of the additional features to the slot and whether they improve the overall experience.
Entertainment Value
Here, we combine all of the elements examined to reveal the overall entertainment value of the slot. We look at whether we enjoyed the experience regardless of wins or losses. Will the slot leave you wanting more, or will you never return? You can find out what we thought without spending a penny.
The Overall Rating
We rate each of the examined elements with a percentage score. The overall rating is simply an average of all the elements and that should at least give you the heads up of what you can expect.

Hall of Fame
Each month, we’ll be looking over our 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 our 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 we’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, we’ll let you know! This month’s award goes to Lil Devil, and you can find out why in our review below.
