What is a no deposit bonus?

A no deposit bonus is a reward offered by online casinos that doesn’t require the player to deposit their own money to get the benefits of the offer. 

No deposit bonuses are one of the best rewards you can get from an online casino but they’re also one of the rarest. This is because most gambling sites insist on players making a deposit (even if it’s a small one) to get the benefits of a casino bonus. 

This is why a free no deposit bonus is one you should give real consideration to if it’s offered by a reputable online casino, as most rewards aren’t so generous.  

Types of no deposit bonuses

There are two different types of casino no deposit bonus offers you can get from an online casino — a cash offer or a free spins offer. This is what you need to know about the two no deposit casino bonuses: 

• Free spins casino no deposit bonus:get some free plays on online slots games, such as 50 free spins on a top title 

• Cash casino no deposit bonus:get some bonus funds to use on great casino games, such as £100 to be used on live dealer games 

A cash no deposit bonus is potentially the best of the two offers, as this can often be used on a broader range of casino games — from video titles to live casino games. However, the right one for you depends entirely on what you’re looking for in a casino offer. 

So, think carefully about what bonus suits you best and then look for online casinos offering no deposit bonus codes. 

How to claim a no deposit bonus

Claiming a no deposit bonus is really straightforward. 

All you have to do is go to the promotions page of the casino, find the bonus and then follow the instructions laid out by the online casino. How the instructions look will depend upon the specific site you use but these are the things can expect to be asked: 

• Sign up for an account (if you don’t already have one) 

• Submit your identification (if you’ve not already done so) 

• Select the ‘claim bonus’ button 

• Open any no deposit casino bonus codes sent to your email inbox 

• Activate your no deposit bonus 

Online casinos want it to be as easy as possible for you to get your bonuses because they want you to spend them on their games. This is why (no matter what the exact process is) signing up for and claiming a no deposit bonus will always be straightforward. 

No deposit bonus wagering requirements explained

Wagering requirements are one of the key things to know about no deposit bonuses. 

Given that you don’t need to make an initial deposit of your own cash to sign up for a no deposit offer, it would be simple to fall into the trap of thinking that this is a totally free bonus. Wagering requirements mean the offer isn’t quite a gift of free bonus money

The reason wagering requirements are so important is that they’re the amount of your own money you need to invest (wager) before you can withdraw the winnings you make from a no deposit bonus. 

Below, we explain how wagering requirements work by using the example of a £100 no deposit bonus: 

• 10x wagering requirements: you need to wager £1,000 of your own cash 

• 20x wagering requirements: you need to wager £2,000 of your own cash 

• 30x wagering requirements: you need to wager £3,000 of your own cash 

Qualifying wagering contributions vary from casino to casino. Some sites (such as PlayOJO Casino) have no wagering requirements, others have requirements of 50x or even higher. 

In summary and in simple terms, wagering requirements are instances when no deposit bonuses ask you to deposit your own cash. 

No deposit bonus terms & conditions

Bonus terms and conditions (T&Cs) are something it’s easy to overlook when deciding which casino rewards to sign up for. 

T&Cs are dense, detailed and often dull because they’re legal text that online casinos must include to give players a full picture of the bonuses they’re signing up to. 

But T&Cs are something you really need to pay attention to because they explain precisely what you’re getting from a reward, from the wagering requirements you need to meet to any caps on your bonus winnings. 

We recommend you read every T&C for a bonus you're interested in before signing up to it. You can find the T&Cs in the advertisement for the offer. 

No deposit bonus online casino payout rates

Casino payout rates aren’t something that relates immediately to bonuses. However, they’re really important when it comes to deciding what the best no deposit bonus casinos are for you. 

Payout rates are what give you an indication of your chances of winning when you play games at an online casino. As the name suggests, they’re the rate that games pay out — the frequency at which you could win. 

Payout rates are represented as RTP (return to player) which is displayed as a percentage. RTP shows the percentage of money wagered that’s paid back to casino players over time. 

Using the example of a £100 wager, this is how RTP works: 

• RTP of 93%: £93 is returned to players over time. 

• RTP of 96%: £96 is returned to players over time. 

• RTP of 99%: £99 is returned to players over time.

The thing to remember about payouts (or RTP) for casino games is that it’s just an indication of what could happen based on past results. What you must keep in mind is that casino games are based (to varying levels) on chance. This means you could win either more or less than £99 if a game has an RTP of 99%. 

No deposit bonus mobile casinos

Rewards aren’t the only consideration during your online casino no deposit bonus assessments. Indeed, bonuses should be (at best) secondary to gambling experience and casino gameplay. 

One of the most important factors in gambling experience and casino gameplay is a gambling site’s mobile offering. 

All UK online casinos can be played on your mobile phone but how you do so depends on a site’s mobile offering. These are the two types of mobile gambling experience offered by UK online casinos: 

• You bet by logging into the casino via your mobile browser 

• You bet by logging into the site via its casino gambling app 

Logging in via your mobile browser has the benefit of saving space on your mobile phone, as you don’t have to download an app. But it has the disadvantage of providing a lesser playing experience, as casino websites aren’t as geared towards mobile gambling as apps. 

Logging in via a casino app has the benefit of offering a superior mobile gambling experience because the application is designed for playing casino games on your phone. But it has the disadvantage of taking up space on your phone because you need to download the app. 

Ultimately, the decision as to which mobile gambling method works best for you is one you must make. However, from experience, we’d say using an app is better than a mobile browser. 

Licensing & legislation of the best no deposit bonus casinos 

No deposit bonuses are super important when listing the best casinos – they’re a chance to get some free money or free spins on great slots games. 

But one of the non-negotiable features of betting sites is that you feel safe when you’re gambling there – after all, you’re spending your money there and cashing out your winnings. 

Licensing and legislation is the way to establish that the online casino you’re using is safe. 

The reason for this is that the licensing and legislative bodies that regulate gambling sites are responsible for keeping them in check and keeping you safe 

You can be sure that you’re using a licensed and regulated casino by keeping an eye out for the icons of these gambling regulators.

Recent online casino regulation that relates to UK sites 

Every online casino that operates in the UK is regulated by the Gambling Commission, the UK government’s organisation for enforcing gambling legislation. 

The Gambling Commission issues licenses to all gambling sites (you can usually find a site’s license number displayed on the footer of its web pages) and exists to ensure UK players are protected when they bet online. 

To ensure UK players are provided with the highest possible level of protection, the Gambling Commission constantly reviews industry legislation and introduces new steps when it feels it’s necessary to do so.

It was announced in February 2021 that there would be updates to online casino regulation, with new gambling restrictions being introduced to reduce the intensity of casino gaming. The regulatory updates aim to reduce the intensity of casino gaming through the following measures:  

• Gambling operators are required to clearly display to players the losses they’ve made

• Features designed to speed up casino gameplay are permanently banned 

• Features designed that celebrate losses are permanently banned  

• Limitations on the spin speed of slot games are introduced 

The Gambling Commission regularly publishes updates in the casino industry in the news section of its website. Visit the site today to get the latest “news, speeches and announcements from the Gambling Commission”.

Gamification factors at no deposit bonus online casinos

Gamification factors have become increasingly important to the online casino gambling industry in recent years and the likelihood is that this trend will only increase. 

There are a huge number of online casinos for players to choose from and this means casinos have to work hard to keep people gambling on their sites. A lot of this hard work is directed towards gamifying an online casino’s offering.  

These are some of the gamification factors you might see at no deposit online casinos: 

• Levels 

• Missions

• Trophies

The above factors aren’t exclusive to sites that offer no deposit free spins or cash rewards. Any site could use some or all of these factors to gamify its offering. 

Casinos that offer no deposit bonuses have something of an initial advantage over other sites (as a no deposit bonus is a generous offer that will entice many people) when it comes to getting people to sign up. 

However, that’s just part of the battle for the sites. Once they’ve got players to sign up then they need to keep them interested. This is why you can expect to see more and more gamification factors at gambling sites, even those generous enough to offer no deposit casino bonuses.

This makes it separate to our list of the best no deposit bonus casinos because in that review we looked at the whole package offered – including welcome bonus, games, payouts, and more.

While no deposit bonuses are among the best rewards you get from online casinos, they aren’t the only ones on offer – there are some other great ones you should look out for. 

Welcome bonuses are one of the best alternative introductory offers you get from gambling sites. Why? Because they give you a chance to earn some free money by depositing some of your own money.
