First Deposit Slot Bonuses at UK Casinos

It is our job to advise you on where you can find the best online slot bonuses. But before we do this, we would like to make one thing clear.

Bonus money is almost always subject to wagering requirements.

Despite what an online casino tells you, there is nothing free in this world. Casinos will offer you a variety of bonuses but in reality, these bonuses come with terms and conditions.

Welcomes Bonuses

Welcome bonuses are an extremely standard feature of all UK casino operators. A lot of casino players choose a casino based solely on the welcome bonus it offers but we would advise against doing this.

Instead, you should choose a casino based on its stock of slots games and how comfortable you feel playing at that specific casino. If you are picking a casino based on how good its slot bonus is, you might be in for a surprise once you work out how casino bonuses work.

Wagering Requirements

Casino and slot site bonuses all come with wagering requirements. These requirements only allow you to withdraw after you have wagered the bonus a certain number of times. Bonus wagering requirements can always be found in the terms and conditions. So, make sure you check them!

How do wagering requirements work?

This is something you need to know before you pick a casino bonus.

If you decide to go with a casino that is offering a 100% deposit match bonus and you deposit £50 and play with £100, the bonus will need to be wagered a number of times before you are allowed to withdraw any of it. Wagering amounts vary from casino to casino, so before you choose a slot site to play at, it is important that you know how many times you are required to wager their bonus.

If we use the standard casino wagering requirement of 30x, you will have to wager your £50 bonus 30x before you can withdraw any winnings associated with that bonus. This means you will have to wager through £1,500. What’s more, some casinos will only allow you to use your bonus on specific slots or casino games.

In short, casinos make it as hard as possible for you to actually win any money using your casino bonus. The best way to wager through your bonus though is to play online slots. Regardless, before depositing, make sure to read the terms and conditions!

The Different Types of Slot Bonuses

There are several different varieties of slot bonuses offered by UK casinos which we have listed below for your satisfaction.

Welcome Bonuses

New players are likely to receive welcome bonuses. These are usually in the form of match deposit bonuses. As mentioned earlier, these are where you make a deposit and the casino will match your deposit.

PlayOJO casino has zero wagering requirements on their bonuses, so we can recommend playing at this casino. However, there is a cap of £100 in winnings.

Free Spins

There are two different types of free spin bonuses; extra spins you receive for depositing and no deposit free spins. Wagering requirements almost always apply here too. Some casinos also limit the slots in which you can play your free spins on.

The casino has an incentive here for you to lose your free spins as quickly as possible.

PlayOJO casino offers 100 free spins with zero wagering requirements. They cap winnings at £100 though so you will not be able to win anymore than £100 using your free spins.

Deposit Bonuses

Deposit bonuses are usually open to first time depositors and loyal customers. Casinos will often have seasonal promotions where they offer their players a bonus if they make a deposit. The large deposit bonuses are usually held back for new players to entice them into signing up. These bonuses will all come with requirements so make sure you read the terms and conditions!

If you are interested in one of the best deposit bonuses, check out our deposit £5 play with £30 bonus and deposit £5 play with £40 slots bonus.

Alternatively, we also have a deposit £10 play with £60 slots bonus for you to check out.

No Deposit Bonuses

Simply registering at a casino and having funds transferred straight into your account, sounds too good to be true, right? Well, it kind of is. These bonuses are usually cash amounts or free spins.

Our partner Monster Casino offers a £5 no deposit bonus. However, this comes with many wagering requirements. We would like to reiterate, please only sign up to the casino which has a library full of your favourite slot games. Your enjoyment is worth more than any slot bonus.

How to Redeem your Slot Bonus

If you are unsure how to get yourself a slot bonus, simply follow the steps below.

  • First step: Pick a Casino – Select a casino from our list above. When choosing which casino to play at, ensure you choose a casino that has a library which contains your favourite games. All the casinos listed at Labslots are 100% safe and regulated but they each have their own individual pros and cons.
  • Second Step: Register and Open an Account – To gain access to any casino bonus, you first need to register an account at your chosen casino. UK regulations state that you must present a valid ID to the casino. You must also be at least 18 years of age.
  • Third Step: Activate your Slot Bonus – Once you have confirmed your new casino account, you will receive bonuses such as no deposit bonuses and no deposit free spins bonuses.
  • Fourth Step: Make a Deposit – To receive your deposit bonus, you must make a cash deposit into your casino account. You can use various banking methods to make a deposit.
  • Final Step: Play – Once you receive your slot bonus it is time to start playing. Before you begin, make sure you know how many times you must wager your bonus.

Making Use of Casino and Slot Bonuses the Correct Way

We are certainly not against slot bonuses; they can be very useful if they are used well. It is our objective to ensure that you are not misled by bonuses of any sort. A large percentage of slot players do not pay attention to the terms and conditions and then get upset when a casino tells them why they are not able to withdraw their ‘winnings’.

Our advice is not to worry too much about the bonuses. Concentrate on your own money and with that you will not have to worry about any wagering requirements.
