What is a no deposit bonus and how does it work?

A no deposit bonus is a casino bonus which is most often given when a new player registers at a casino or betting site. There are other times when an online casino gives players a no deposit bonus for performing a certain action. Players can use this bonus anytime like when placing several bets on a game, playing a slot game, or even during a table game.

The great thing about a no deposit bonus is that you do not need to use your funds to obtain this bonus. Nevertheless, it usually comes with high wagering requirements and other limitations if you compare it with other types of bonuses.

How do we choose the best no deposit bonus casino bonus sites?

Every online casino and betting site is unique in its own way. That is why it is imperative that you know how each works. Here we will go through the several factors that our experts at Gambling Zone look at when we are evaluating the best no deposit casino sites.


At Gambling Zone we check whether the gambling sites have been audited by an independent third party. Two of the most highly respected certifications are the eCommerce and Online Gaming Regulation Assurance (eCOGRA) certification and a Technical Systems Testing Labs (TST) seal. We will also check if the site utilises state-of-the-art protection such as the latest Secure Socket Layer (SSL) as well as Transport Layer Security (TLS) systems. Finally, our experts will also check if the casino or sports betting site is on any blacklists or has any pending consumer complaints.

Fully licensed

All casinos and betting sites that we recommend must be certified by the UK Gambling Commission (UKGC), the regulatory body that issues and oversees UK-based gambling businesses. For Ontario-based casino enthusiasts, we only recommend sites with an Alcohol and Gaming Commission of Ontario (AGCO) licence. However, if you live outside these areas, we will then recommend betting sites that have a Malta Gaming Authority (MGA) licence or the applicable local licence.

Mobile Friendly

Among the things we look for in an online casino is the ease of use. This involves being handy and easy to access. Since most players access gambling sites on a mobile device or tablet we will check whether the no deposit bonus can be accessed using your mobile device. Our experts will not differentiate between the site being available on mobile devices in the form of a mobile web optimised version or a separate downloadable app. Either is a huge advantage.

Evaluate the no deposit bonus terms

While the terms and conditions used by online gambling sites are similar it is still important to check each as even the smallest differences can have major consequences in regards to whether a bonus is advantageous or not. We will discuss the different terms and conditions attached to a no deposit bonus in more detail below and we will also explain how each term can affect the worth of the bonus.

Casino games selection

A no deposit casino bonus is usually connected to a specific game or type of game. Most often, online casinos use this bonus to feature their newly-released games. Some choose to place it on their most popular games. Most commonly, the online casino or betting site will give a no deposit bonus on online slots or sports betting.

Different types of no deposit bonus casino bonuses

Various types of no deposit bonuses exist at online casinos and in sportsbooks too. You can see these bonuses on their Promotions tab. At times, they just pop up, or go straight to your inbox when you sign up for their newsletter.

Here are the most common types of no deposit casino bonuses that you will find offered to players from the UK. The Gambling Zone experts will also give some important pros and cons for each one so that you can evaluate which bonus is the most useful.

Sign up no deposit bonus

This particular bonus is also a registration bonus. The casino or betting site offers this to new players that have completed the registration process. It is quite uncommon to see this type of bonus at many betting sites. A sign up no deposit bonus also has many restrictions and limitations placed on it, which includes high wagering requirements, a cap on max winnings, and is usually a small amount.

Pros Cons

Rewarded to new members as part of the welcome package

Bonus amount is not that high

Test games free of charge

Comes with several limitations

No need to use real money funds

May have play through terms

No deposit Free Spins

Online casinos offer no deposit free spins to let players test out their slot games. These free spins can turn them into loyal customers. No deposit free spins can be part of the welcome package or can be part of some other type of promotion.

Just like the no deposit casino bonus, these free spins means that players will not need to use any real money funds in order to obtain the spins. However, there are usually a good number of restrictions put on any winnings from no deposit free spins as well.

Pros Cons

You can use this in various online slot games

You are forced to bet small amounts

No need to make a real money deposit

May come with wagering requirements

Benefits both new and existing players


Allows you to test new games

Cashback Bonus

A cashback bonus is the amount given to players to compensate for their net losses. This lets players get back a percentage of what they lost on a specific game or set of games over a given period.

Usually, the cashback bonus is given to long term members for their continued patronage and support. This aims to improve customer satisfaction and keep them as loyal players. There is also an upper limit on the amount to be returned by the casino. The gambling site usually returns the amount as actual real money or as free bet credits.

Pros Cons

The funds can be withdrawn without any wagering requirements

You need to lose money to get the bonus

Cashback bonuses reimburse you for weekly or daily losses

Not all games are covered

Will get the funds back as real money

No wagering Bonus

The great thing about this bonus is that there is no wagering requirement attached to the bonus amount. Essentially, that means that the bonus is in real money funds, and it is not bonus money.

This bonus is uncommon nowadays but still advantageous to the player. In this case, the casino or betting site is giving the player real money funds which they can do whatever they like with. They can play any game, place any bet, or they can just withdraw the amount.

Pros Cons

Try new games without risking real money

Bonus is available in low amounts

Players are not tied to wagering requirements

Difficult to find

No play time limits

No Deposit Bonus terms and conditions

One of the most significant factors to help you determine if a no deposit bonus is worthwhile is to understand the terms and conditions. Players must know that each bonus is unique and has its own requirements. Getting a no deposit bonus can be fascinating but if it comes with so many restrictions, it is no longer exciting and rewarding.

At Gambling Zone our experts have put together this guide with helpful insights on how to understand and handle these terms. Here are the most common bonus terms and conditions which are attached to a no deposit casino bonus.

Banking Options

Although this type of bonus does not require a deposit, you should consider how you are able to withdraw your winnings.

The most common payment options are debit cards, prepaid cards, e-wallets, bank transfers, and cryptocurrencies. Most players prefer using a debit card because they can avoid extra fees. However, it may take 3-5 days to clear. Bank transfers are the least favourite as withdrawals may take up to 5 days

Wagering Requirements

A condition where a player must rollover the bonus multiple times before cashing out winnings is called a wagering requirement. This is referred to as rollover or play through, as well. Be sure to read the wagering requirements carefully to avoid encountering issues during the cash-out process.

Here's how a wagering requirement works:

Scenario: A player receives a £20 bonus and the wagering requirement in order to withdraw the winnings is 10x. The player must wager the bonus ten times or a total of £200 to cash out the bonus amount and any potential winnings.

Bonus Expiry Time

Usually, no deposit bonuses are valid from a few days to a week’s time. However, some can last up to a month. Players can easily spot the expiration date in the bonus description.

There is a given time frame for claiming the bonus and failure to do so results in forfeiture of the bonus. Casinos also place a time limit on the wagering requirements.

No Deposit Bonus Final Words

Rest assured that here at Gambling Zone we are here to guide you and make sure you stay ahead of the game with the most up to date information you need. It is our goal that our guide will help you choose the best no deposit bonus casino site that can have a huge impact on your gameplay. 

A few final pointers from us are:

Select bonuses that are less restrictive

Some bonuses have many restrictions that were placed for many reasons. However, if there are too many limitations and restrictions, then it might be better to try and find a different bonus.

Read reviews

In order to learn about a certain casino and how its bonuses work, check out reviews left by players. Likewise, read the unbiased and comprehensive reviews from Gambling Zone.

Always learn the Wagering Requirements

A no deposit casino bonus is attached to wagering requirements. Check to see how low or high this requirement is before you decide to claim the bonus.

Don’t expect to win big

Ultimately a no deposit bonus is not really going to be big enough to allow you to win big. You have to understand that the real purpose of this bonus is to allow you to try out some new games and to enjoy yourself playing something different which you might not have tried out if you were using your own funds. Use this bonus to get a feel of how the casino works. Learn from the experience then use your acquired skills on your next game.

Play games that have low volatility

If the no deposit casino bonus is not restricted to a specific game, try choosing games that have low volatility. These types of games may not bring you huge winnings but can give you small yet steady gains and an extended amount of playtime.
