As well as honest slot reviews, we also list the very best online casinos, to give the most generous offers around. However, we wont just list any casino. All the casinos featured are ones we have personally played at. Just like slots, we understand that everyone will have a differing opinion, but the casinos we feature must comply with the standards we expect in terms of fairness, security, and social responsibility.

Trusted Casinos

Online Slot Master will point you in the right direction for the most trusted online casinos who offer the best sign-up bonuses. Our go-to casinos at the moment are Casumo, PlayOJO and Slots Magic, and you can read our by clicking the links. Whether you’re looking for free spins or enticing bonus offers, we’ve got you covered. Finding your favourite online casino is ultimately a matter of preference, and will probably end up depending on how often you win! However, there can be much more to it when choosing where to spend your money, with great customer service and fast payouts being amongst the top factors that we look for when determining the very best casinos to play at.


Featured = Quality

All the casinos we feature at Online Slot Master must tick our boxes on quality. For example, we will never list any casinos not licensed with the UK Gambling Authority. In fact, the casinos we recommend will invariably hold many more licenses, and will also be independently audited. We only want to play at casinos that are fair and transparent, so we will only recommend those who are.

The best casinos online will have state of the art encryption. This is not only important for your transactions, but also for your privacy. If a casino isn’t up to scratch in that regard, then they wont be listed here. Finally, we expect all the casinos we list to protect their players with robust responsible gambling measures. Playing slots should be fun, and we wont recommend anywhere that doesn’t have protection measures in place.

Best Online Casino Bonuses

Picking the best online casino to play at will often be influenced by the sign up bonuses they offer. Most will match your first deposit up to a certain amount, and most will also offer free spins too. These are all great tactics that casinos will use to get you through the door. However, we would always urge you to look at the terms and conditions of any offer as most will come with wagering requirements. PlayOJO ranks highly ranks highly at Online Slot Master, because their offers come without wagering requirements. This makes them great if you’re new to online casino play, or if you simply can’t be bothered working out how much you need to play before you cash out.



It’s often worth looking beyond the initial sign-up bonuses at any online casino. Some of the best will also reward player loyalty too. Videoslots are a great choice for this, as they offer a weekend booster where a proportion of your weekly deposits are returned to you as cashback. Other casinos offer similar incentives, and if you can’t see the offer immediately, it’s always worth an ask via their online chat. Long before we started Online Slot Master, we would often just ask customer service for a bonus and they would oblige in a lot of cases as a reward for loyalty. In short, remember that no matter which online casino you play at, they will always want to keep your custom so don’t be shy in asking for bonuses!
