No deposit bonuses are massively popular with players. As the name suggests, you do not need to make a deposit to unlock the bonus, allowing you to try out the casino before playing with your own cash.


There are two types of no deposit bonuses up for grabs: free cash and free spins. With both bonuses, you can win real money — subject to the terms and conditions (T&Cs) of the bonus offer, of course.


Once you have used the bonus and so long as you like what the casino has to offer, you can then make a deposit via your preferred payment method and keep playing.

What is a no deposit bonus?

It is a promotion where the casino offers new players a bonus without requiring them to make a deposit first. This is usually in the form of bonus cash or free spins.

They are a great way for you to try an online casino before making a deposit and playing with your own money.

Difference between a no deposit bonus and no deposit free spins

If you’re claiming a no deposit bonus, it's important to know exactly what you’re getting and the differences between the two main types of bonus: no deposit bonus cash and no deposit free spins. So, let’s take a quick look at each…

No deposit bonus free cash

This is credit given to you that can be used on all games in the casino lobby – slots, table, crash games, scratch cards, live dealer, bingo and more. The value is usually between £5 and £20.

No deposit free spins

This is a set number of free games that are played on slots – in most cases, this will be a specific slot game. The number of free spins offered can run into the hundreds, and spin values range from £0.05 to £0.20 per spin.

Which is better - free cash or free spins?

Whether free cash or free spins is better is down to what you want to play. If you’re keen to play slots then the free spins bonus is the perfect fit, but if you’re looking to enjoy other casino games then free cash would be the way to go.

Usually, there isn’t too much of a difference in terms of the amount of money given to you with free cash or free spins, but there’s a quick way to figure out if they’re indeed one and the same.

Casino A is offering players the choice between two no deposit bonuses: £5 of free cash or 25 free spins at £0.20 per spin on the latest slots game available.

The value of the free cash is, obviously, £5, but to work out the value of the free spins you need to multiply the number of free games by the value of each spin.

In this case, it would be:

25 spins x £0.20 = £5

So effectively you’re getting the same value no matter your choice of free cash or free spins. But if the casino was offering £5 of free cash or 30 free spins at £0.20 each, you’re getting slightly more – £6 – of value out of the free spins.

Why claim a no deposit bonus

If the idea of free cash or free spins isn’t enough to encourage you to claim a no deposit bonus, these are some of the other upsides to these offers.

Use the bonus cash to try the casino before depositing your own money.

Play different slots and casino games for the first time. With bonus cash, try new game types such as crash, instant win, live dealer and more without using your own cash.

The number of free spins up for grabs can be high, with some casinos offering hundreds of spins without having to make a deposit.

More and more casinos now offer no deposit bonus cash and no deposit free spins to players so there's a great selection of brands to choose from.

No deposit bonuses and a few things to consider

Nothing really comes for free, right? The same applies to online casino promotions, including no deposit bonuses. And that’s why casino offers have T&Cs.

The terms and conditions are specific to each online casino bonus, so it’s important to read them and understand what they mean before claiming an offer.

This is because the T&Cs can reduce the value of the bonus when you factor in things like win limits and wagering requirements.

That’s not to say a no deposit bonus does not add value to your play, but being aware of the T&Cs means you know exactly what the bonus ultimately delivers.

No deposit bonus T&Cs to be aware of

T&Cs for no deposit bonuses can be quite lengthy, so we've broken out the key terms to be aware of, what they actually mean and the impact they can have on the bonus offer.

Maximum bet - The maximum amount you can bet on a single spin or game round.

Cap on bonus winnings - The maximum amount you can withdraw from the bonus.

Wagering requirements - How much you need to playthrough before you can withdraw your bonus as cash.

Limited game selection - The games can and can't be played with the bonus.

No deposit bonus on sign up - You might need to complete the sign-up process, including providing a deposit method, before the bonus is awarded.

Casino bonus wagering requirements explained

The wagering requirement is the number of times you have to wager the bonus amount or your winnings before you can withdraw the bonus amount or your winnings as cash.

Wagering requirements vary significantly from casino to casino and bonus to bonus. Low wagering casinos will impose playthrough requirements of between 10x and 30x, but they can be as high as 65x at some brands.

There are a growing number of UK online casino sites that impose no wagering requirements whatsoever – although the no deposit bonus value offered is usually much less, it’s your money to play with and withdraw as and when you want.

Calculating the wagering requirement on a no deposit bonus is pretty simple. Here’s what you need to do.

Take the bonus amount claimed or your winnings from the bonus (check the T&Cs to see which it is) and multiply this by the wagering requirement.

This gives you the total amount you have to wager before you can unlock your bonus or winnings as cash.

How to calculate the wagering requirement

Still not sure how it works? Check out the example below.

You’re offered a no deposit free cash bonus of £10 with a x30 wagering requirement on the bonus amount.

Bonus: £10
Wagering requirement: x30
Amount to be wagered: £10 x30 = £300

This doesn’t mean you have to deposit and lose £300, just that you need to cycle that value through the casino before you can unlock the bonus money as cash, or if the wagering requirement is applied to your winnings, your winnings as cash.

There are some casinos that do not impose wagering requirements, no wagering casinos, so you can keep what you win with fewer strings attached.

How to get the most out of a no deposit bonus

The best way to make sure you get the most out of a no deposit bonus is to understand the terms and conditions attached to the offer.

You should check the bonus cap as this ultimately determines the amount you can win from the bonus. But it’s also important to be realistic – you get a small bonus to tempt you to try the casino for free. You’re unlikely to win big especially when the T&Cs and wagering requirements are applied.

If you don’t like the idea of having to complete the wagering requirement, look for no wagering or low wagering casinos that also offer no deposit bonus.

Ultimately, use no deposit bonuses to have fun and try the casino before using your own money.

An important word on responsible gambling

Online casino is fun and enjoyed by millions of people across the UK. But it’s important that it does stay fun and that you remain in control of your play. Because we only partner with UK-licenced online casinos, each of the brands listed on Comparasino offers the tools you need to do this.


But some of these tools might be unfamiliar and it can also be tough to determine if you, or a family member or friend, could potentially have a gambling problem. That’s why we’ve created a Safe Gaming Hub where you can find information about all the responsible gambling tools offered at online casinos, how they work and which ones might be best for you.


It also contains insights into some of the early signs of problem play to be aware of in yourself and others as well as direct access to charities and organisations that support those with problem gambling habits.
