In researching the best no-deposit bonuses, we sign up for numerous casino accounts and carefully read the terms and conditions at each site to check the quality of the offers available. Aside from reviewing the terms of the free casino bonuses, we also consider the following before making our recommendations:

• Licence: If an online casino is unlicensed, we don’t recommend it. We first check where the casino is licensed and regulated to ensure your safety and security while gambling online.
• Payment terms: We then consider how a casino permits you to deposit and withdraw funds. Variety is essential, and we like to see that e-wallets, debit cards, mobile payments, and bank transfers are all supported. We expect instant deposits and withdrawals within 1-3 days and no fees attached to any transactions.
• Game variety: The best online casinos provide access to thousands of games by dozens of casino software studios. We like to see slots, table games, and live dealer titles from award-winning studios like Pragmatic Play and Playtech.
• Customer support: Given that some customers experience issues related to no-deposit bonuses and other promotions, the quality of a casino’s customer support team is important. We contact a casino’s customer support agents in numerous ways and test their responsiveness and efficiency. If a casino fails to make the grade, we don’t recommend it.
• Mobile optimisation: A no-deposit bonus casino should be optimised for mobile gameplay. We test the casino experience on mobile browsers, and where available, we download the native iOS and Android casino apps to test them. Our recommended sites offer thousands of mobile-optimised games that provide seamless gameplay on smartphones and tablets.

Our reviews are objective and thoroughly researched, and we only recommend online casinos that score highly against our strict criteria. Therefore, you can trust us to recommend the best casino bonuses with no deposit required that are currently available to new customers.

What is a no-deposit bonus? 

A no-deposit offer is a registration bonus available to new customers without requiring a deposit in return. To access the offer, you only need to register for an account by providing your personal and contact information.

It’s a brilliant way to test out a casino’s offering before committing to a real money deposit. If you like the casino, you can continue playing by adding funds to your account. If you don’t like it, you can walk away without spending anything.

How to access a no deposit casino bonus

No-deposit bonuses are straightforward to access and only require you to complete a few simple steps to get started:

1. Check the offer’s availability: First, check that the no-deposit bonus is available in your state or country. Then, read the terms and conditions attached to the promotion and check if you need to enter a promo code to access it.
2. Create an account: After familiarising yourself with the promotion, create an account at the online casino. You will need to provide your personal and contact details to complete the registration process, and you may need to verify your phone number or email address to finalise the process.
3. Play games: Upon completing the registration process, check that the funds or free spins have been added to your account balance. Then, play the eligible games for free. If the funds or spins don’t appear in your account immediately, contact the customer support team to learn more.

The different types of no deposit bonuses

Our research found two main types of no-deposit registration bonuses at online casinos:

No-deposit bonus cash

The first and most common type of free welcome bonus with no deposit required is bonus cash. Here, the casino issues credits added to your balance as soon as you create your account. Typically, this is a relatively low amount, which could be £5 or £10. You can use the funds to play a few slots and table games, but the money is not withdrawable. If you win while playing, you must satisfy wagering requirements before cashing out.

No deposit bonus free spins

The other popular promotion is the free spins, which are a no-deposit offer. Rather than adding funds to your account, the casino issues free spins to your balance, which you can use on selected slot games. Again, you’re likely to receive a relatively small number of spins (perhaps 10 or 20), and you can only use them on one or two games. Though free spins are more restrictive than the bonus cash offer, they’re still a great way to test out a casino before committing to a real money deposit.

The pros and cons of a no-deposit bonus casino

So, why should you sign up for a casino that offers a no-deposit bonus? Here are some of the pros and cons of casino welcome bonuses available with no initial deposit:

Pros

✅ Risk-free: You don’t need to spend money to access a no-deposit bonus, so the promotion is 100% risk-free. If you dislike the casino, stop playing and walk away without making a real deposit.

✅Free casino bonus: A no-deposit bonus is a truly “free” casino bonus, requiring no investment as a new player. Though payout restrictions exist, this is a great way to test out a casino’s slots and table games for free while deciding whether to become a real-money player.

Cons

❌Offer limitations: No-deposit bonuses are limited in size and scope. They’re usually only available for small amounts (perhaps £10), can only be used on a small pool of games, and have maximum win limits.

❌Wagering requirements: You must satisfy wagering requirements before cashing out any winnings obtained from a no-deposit bonus. Always check the casino’s terms and conditions to determine how much you must spend to satisfy these requirements.

No-deposit bonus vs first-deposit bonus – what’s the difference?

As attractive as no-deposit casino bonuses are, they’re not widely available. Most casino bonuses require an initial payment to activate the welcome package. In other words, you must make at least the minimum deposit to receive the bonus funds or free spins.

This type of promotion is known as a first 5 GBP deposit bonus, with the funds available as soon as you make an initial deposit at the casino. Below are some of the differences between the two promotions so you can decide which is best for you, depending on your preferences:

Key terms and conditions attached to no-deposit bonuses

Checking and understanding the terms and conditions attached to a no-deposit bonus will help you maximise the promotion and access the full extent of the bonus. Here are some crucial things to check for before signing up and accessing the promotion:

Wagering requirements

Every no-deposit bonus that we encountered in our research had wagering requirements attached. This figure indicates how much money you must spend before cashing out any bonus winnings. This can range from 1x to 100x, so you must check in advance.

For instance, if you access a £10 no-deposit bonus with a 10x low wagering requirement, you must spend £100 of your bankroll before cashing out your winnings. The lower the wagering requirement is, the better the value of the promotion.

Maximum win

Most no deposit registration bonuses stipulate a maximum win amount you can’t exceed. This means you can’t win jackpots and huge payouts while playing online casino games with your no-deposit bonus. Instead, you will likely find that the maximum win is capped at a relatively low amount, perhaps £50 or £100. This is one of the biggest limitations of no-deposit bonuses and something to be aware of before signing up.

Timeframe

No-deposit bonus casinos stipulate how long you have to access the promotion and satisfy the wagering requirements. Our research found that most casinos require you to use the free spins, no-deposit, or bonus cash within 24 to 48 hours, so you need to be quick. Free bonus spins without an initial real money deposit tend to be available for a shorter period than first-deposit promotions, reflecting that you don’t need to unlock this promotion with an initial stake.

Game eligibility

Casino welcome bonuses with no deposit are usually restricted to one or two games. Often, you can play one or two slots or table games, but live dealer games are usually unavailable. If you want to use a casino’s bonus funds on a broader selection of games, look for first-deposit welcome bonuses, often available on more slots and table games.

Country availability

Another thing to check for is where the no-deposit promo is available. Even if the casino is legal in your country, the bonus without deposit might only be eligible in a specific state or region, which is common with US casinos that operate in multiple states. So, check the small print to ensure the no-deposit bonus you want to use is available where you live.

Gamble responsibly to maximise your bonus

A mistake that many casino players make is to treat a no-deposit bonus like it’s free money rather than an extension of their available bankroll. When you unlock your no-deposit bonus, you should adjust your stake and play games with reasonable wagering limits to keep your bonus funds going for as long as possible.

Then, when you’re ready to play for real money, you should set deposit and time limits and take advantage of reality checks at your chosen casino to help you stay in control. You can also visit the casino’s responsible gambling portal for further tips and tools to gamble within your means.

What is a casino welcome bonus with no deposit?

It’s a registration bonus at an online casino in the UK when you create and confirm your account. It’s different from other new customer bonuses as you’re not required to deposit to unlock the promotion. Instead, as soon as you create an account and confirm your identity, the bonus cash will be added to your account, which you can use to play slots, video poker, table games, and other titles at the online casino.

Do free casino bonuses exist?

Yes, free casino bonuses do exist in the form of no-deposit promotions. They’re free because you don’t need to spend any money to trigger the promotion, and the funds are automatically added to your account when you sign up. However, if you want to cash out any winnings from the promotion, you will need to satisfy the wagering requirements in the given timeframe, so in this sense, the bonus comes at a cost.

How to withdraw winnings from no-deposit real money bonuses at casinos?

If you land wins while playing with funds from a bonus that does not require a first deposit, you must satisfy the wagering requirements before cashing out. The wagering requirements attached to no-deposit bonuses can range from 1x to 100x, depending on the casino. So, if you intend to cash out your winnings, ensure you have sufficient funds to play through any winnings.

How do you unlock free spins at online casinos with no deposit?

If an online gambling site offers free spins as part of its no-deposit bonus, you must create an account to access the bonus. You should also read the terms and conditions carefully, as you might need to opt-in for the bonus or enter a special promo code to trigger the free spins and without deposit promotion.

What are the best free bonus no-deposit slots?

Online casinos stipulate which games you can play with its free spins or bonus cash, meaning you’re restricted in your choice of games. That said, Play’n GO’s Book of Dead is a popular free spins slot, as is NetEnt’s Starburst. In our research, we found numerous online casinos offering free spins for these popular games.

Are no deposit bonuses truly free?

Yes, these bonuses do not require any financial commitment. However, they may come with wagering requirements that need to be met before you can withdraw any winnings.

Can I win real money with no deposit free spins?
