New casino bonuses & offers June 2023

New casino sites are worth looking into every now and then because newly launched casinos might've come up with entirely new bonus structures or overall offer better deals than older sites. New online casinos can offer bonuses that are meant to both attract players and challenge other casino sites.

The latest casino bonuses generally feature a solid deposit bonus with some nice bonus spins attached. Sadly, not that many new sites offer no-deposit bonuses, but it's still good to keep both eyes open for these as well. New casino offers can hold great surprises!

Check out the list below and grab new casino bonuses fresh from the oven:

Types of online casino offers

Online casinos use bonus offers in various ways. The best-known are welcome offers, also known as sign-up offers. However, casinos can use bonuses also for making sure the new players keep returning to the casino, and as rewards for a loyal clientele via loyalty and VIP programs.

A casino welcome offer is usually the first one that you as a player will encounter. Casino offers can include one or more of the following common bonus types:

It's also important to understand the difference between deposit and no-deposit bonuses:

We cover these in more detail below.

First deposit bonus

Best casino bonuses UK

The first deposit bonus is an offer you can claim for your very first deposit. This is a limited deal and only applicable to your first deposit. If you choose not to claim or apply this offer on your deposit, it will be lost forever.

This bonus has a number of alternative names, such as a casino welcome bonus and a sign up bonus. In most cases, the first deposit offers are match deposit bonuses. This means that the casino will add a certain percentage of your bonus to your player account as bonus funds.

A standard percentage for a deposit match bonus is 100%. However, the bonus percentage can go up to several hundred.

Here's how different bonus percentages work in practice, with the example deposit of £10:

Many sites use the total balance in their ads. For example, you may see "deposit £20, play with £60". This may sound more appealing to the player. At the same, it blurs the line between your real money balance and the bonus funds.

First deposit bonuses also have a maximum limit drawing a line to how much you can get as bonus funds.

EXAMPLE: The first deposit bonus offer is a 100% bonus of up to £200. You deposit £300, which exceeds the maximum bonus value. Your total will be £500; the initial deposit of £300 plus the maximum bonus of £200.

Have a look at some of the best sites to claim a first deposit bonus:

Free spins and bonus spins

Free spins are free slot rounds to try out a specific game and the casino. Although they're a popular no-deposit bonus type, some spin packages can only be unlocked with a deposit.

The difference between free spins and bonus spins is you can get free spins for free. For bonus spins, you need to make a deposit to claim them.

This difference is important for UK-based gamblers to know, as it is part of UKGC's rulings not to call spins 'free spins' if players have to deposit money to the casino in order to claim the spins.

Pay attention to bet sizes, minimum deposits and the wagering requirements to determine how good the free spin deal is.

Check this table for the free spin and bonus spin offers:

No deposit bonus

Sometimes a casino sign up bonus can be available without a deposit. This is called a no-deposit bonus, and it's something a new player can claim by only completing the registration.

No deposit bonuses usually include one or more of the following:

How to claim a no-deposit bonus?

  1. Choose a casino offering a no-deposit bonus
  2. Create and verify your account
  3. Claim the new player sign-up bonus
  4. Bonuses usually come in bonus funds, tied to wagering requirements
  5. Complete the wagering by playing the games
  6. When the wagering is done, the remaining bonus funds are added to your real money balance
  7. Before you can withdraw, you'll need to confirm a banking method by making a deposit

Casino bonuses with low or no wagering

A normal aspect of a bonus is that when you claim a casino bonus, it needs to be wagered by placing bets on games to turn the bonus funds into withdrawable cash. The number of times the player needs to wager their bonus usually reads in the bonus T&Cs. The wagering requirements can be applied to the bonus funds only, or to the bonus and the initial deposit.

The industry standard for a wagering requirement is roughly between 30x and 40x bonus amount.

EXAMPLE: The casino bonus offer is a 100% bonus up to £100 with a 35x wagering, which is applied to the bonus. You deposit £20 which gets you a £20 bonus. Multiplying the bonus of £20 with 35 totals £700. this means you need to place £700 worth of bonus bets to free the bonus cash to real money.

Once you understand what wagering means and how it works, you can see why a low wagering casino bonus or casino bonuses without wagering are something gamblers avidly try to find. If the wagering requirement is low or hasn't got one at all, it's theoretically much easier to turn the bonus funds into cash you can withdraw. Read more about low wagering casino bonuses or no wagering casino bonuses for more detailed information.

You can learn more about bonus wagering in the bonus terms and conditions section of this article.

Here are some online casinos offering bonuses with low or no wagering:

Best slots to play with bonuses

It can be debated which slot is the best one to play with bonus funds, but there are two details concerning the bonus T&Cs we need to address first:

Casinos usually ban playing jackpot slots and slot games with exceptionally high RTP with bonus money.

In most cases, placing bets on slots count 100% towards the wagering requirements. This means each £1 you bet will advance the wagering completion by £1. The live casino games usually are the worst choice, contributing sometimes as little as 5% or none at all.

The best slots to play with bonuses are generally low to medium-volatility games with a high RTP ratio, as the focus is usually on completing the wagering requirement.

Here are some of our recommendations:

Starburst screenshot

Starburst is a simple slot with medium-low volatility and an RTP of 96.09%. With sticky Wilds and re-spins, Starburst makes a solid choice for playing with bonus funds.

Starburst has a relatively low max win of 500x your bet. But, with up to 3 re-spins at one go and all three middle rows filled with Wilds, this slot has plenty of excitement and fun.

Read more about the Starburst slot game and where to play it!

How 1429 Uncharted Seas slot by Thunderkick looks

This beautiful slot has an RTP of 98.5%, which is very much high up there. Paired with the low volatility level, 1429 Uncharted Seas is one of the best slots for bonus wagering.

1429 Uncharted Seas features expanding Wilds and a bonus game with Free Spins. Max exposure of the slot is moderate 670x your bet.

How Gemix slot by Playn Go looks

This slot is a bit different, as it has a 7x7 grid and wins are paid by symbol clusters. The volatility level in Gemix is medium and the best possible RTP is 96.83%.

Gemix doesn't have Free Spins bonus game, but it does feature cascading symbols, leveling up, and a charge meter that fills up with wins and triggers random boosts for even bigger cash rewards.

If regular slots aren't your thing, give Gemix a go.

Loyalty program - casino bonus for frequent players

Loyalty and VIP programs are popular ways to get even more bonuses from the casino.

Loyalty programs reward players automatically for being active, which means depositing money and gambling.

A good example of a well-executed casino loyalty program would be found at Rizk Casino. At Rizk, players collect Frequent Player Points by playing slots. As soon as there are enough points, the player levels up and gets to spin the Extra Wheel with rewards such as cash, jackpots, double-speed boosts, and free spins. For every tenth level, players get to spin the Super Wheel of Rizk with better rewards.

VIP clubs usually have tailored bonus offers, birthday promotions, VIP events, higher cashback rates, and much more.

In most cases of VIP clubs, the membership does require some heavy-duty gambling before the player can even think about requesting an invite. However, if you currently happen to have a membership in some other casino's VIP club, that can be your ticket to easier approval.

Nowadays, UK-licensed online casinos don't really feature separate VIP clubs, but rather lean towards loyalty programs that are open to everyone without invites or minimum spending limits.

You can read more information about the topic in our casino loyalty programs article where we take a closer look at the programs and how they work.

How to find the best bonus value from online casinos

Casino deposit bonuses

When choosing a casino bonus, there are two main goals:

  1. Get the biggest bonus with the smallest deposit
  2. Complete the wagering and withdraw a big portion of the bonus

Often, these are mutually exclusive. As the bonus sum and the bonus percentage grow, so do the wagering requirements. These in turn hurt your chances of withdrawing.

This is what you need to know to calculate the expected value of a bonus:

Here's how you calculate what you will have left after completing the wagering. It's a bit tricky, so let's break it down into five steps:

  1. Bonus sum = Your deposit x the bonus percentage
  2. The total sum to be wagered = Your bonus sum x wagering requirements
  3. Expected loss = Total sum to be wagered x (1 - RTP)
  4. Expected value = Expected reward - expected loss
  5. "Return on investment" = Expected value ÷ original deposit

EXAMPLE: You get a 100% bonus up to £100. The wagering requirement is 30x (B) and the highest RTP allowed is 97%:

  1. Bonus sum = 100% x £100 = £100
  2. Total sum to be wagered = £100 x 30 = £3,000
  3. Expected loss = £3,000 x (1 - 0.97) = £90
  4. Expected value = £100 - £90 = £10
  5. "Return on investment" = £10 ÷ £100 = 0.1 = 10%

Why is the "return on investment" in quotes? You can calculate how much value you get compared to the money you put down. However, you shouldn't consider the money spent on gambling an investment. Besides, the bonus money only becomes relevant after you've lost your original deposit. A consolation prize would be a more accurate term.

Remember, these calculations only give you averages. The RTP (return to player) of a casino game is based on the results of thousands of rounds. Your results within a single gaming session will vary.

There are some factors that make one bonus more appealing than the other. The best online casino bonus is a combination of:

Now you know how to calculate the bonus value to find the best bonus - now it's time to find the best online casinos with bonuses worth your time!

Bonus terms and conditions

All casino bonuses come with some strings attached. The idea is to guide players to use the bonus on casino games and limit the risk to the casinos.

Every casino and every bonus type has its own specific terms. Some terms are very strict, while others are basically irrelevant to most players. It is always good to read the terms, so you know what you are agreeing to and how you should be playing.

Here's an overview of the terms and conditions you may encounter:

Wagering requirements

How much do you need to bet before you can withdraw your bonus

Wagering requirements are the most common condition you see. It simply means the amount of money you need to bet before the bonus funds can be withdrawn. It is normally shown as a multiplier that is based on either your deposit, bonus or both.

EXAMPLE: If a bonus has a wagering requirement of 45x (D+B):

Wagering requirements can refer to either the bonus amount only, the deposit amount only, or both the deposit and bonus amount together. Bojoko uses the following format to help you easily compare bonus wagering requirements in our casino reviews and sorting tools:

Wagering requirements usually range from 20 to 50 times the original bonus amount, but this figure varies from one casino to the other and can also depend on the bonus type or percentage. Anything above 35x (B) is considered high.

The wagering for Free Spins is usually checked from the amount you win from said spins.

Minimum deposit

The smallest deposit sum that qualifies for a bonus

The minimum deposit is pretty self-explanatory. It just means the smallest deposit you can make to get the bonus.

Usually, you can get the basic match bonus with a deposit of 20 pounds. The casino might have a minimum deposit of £10, but that alone won't be enough to get the deposit bonus.

A minimum deposit is something that plays a major role in high-roller bonuses. These deposit bonuses are often 300%, 400% or even 500% and can go as high as thousands of pounds. The catch is that you need to deposit a large sum to get them. A high-roller bonus with a minimum deposit of £500 is nothing out of ordinary.

Time limits

The time you have to claim the bonus and complete the wagering

Time limit is one of the least important terms simply because you are always given enough time. This term just means that you have a set amount of time to complete your wagering or the bonus will be removed.

A common time limit for a deposit bonus is 7 or 14 days. This is plenty of time for even the largest bonus.

One thing to note is that some free spin offers have very short time limits. For example, if a casino gives you 10 free spins a day, then you will have 24 hours to play those spins.

The time limit is basically there just so people don't forget about their bonuses. Casinos don't want players coming back a year later and asking about their unspent bonus funds. 

Max bet

The largest bet per round allowed when wagering your bonus

Max bet simply means the maximum wager you can place with a single round while using bonus funds. The most common bet limit is £5.

This limit does include every single boost and extra feature you could add to your bet. If the game you play has any of these alternate ways to spend money, just make sure none of it is worth more than the maximum bet limit.

If you ever make a mistake and play with a higher bet than you are allowed, immediately contact customer support. If you are honest about your mistake, they might let it slide.

Restricted games

Not every game helps you complete the wagering

This is a big one. When you get a bonus, its terms will have a list of games that you can't play and some games that aren't worth playing. Make sure you know them because this is the most common reason why people lose their bonuses.

When casinos talk about restricted games, they have a few categories. Some games fulfil your wagering requirement less than 100%, making them less desirable. Some on the other hand are simply forbidden and playing them with bonus funds is a breach of terms.

Casinos have three mechanisms to restrict the games:

EXAMPLE: Playing live dealer blackjack contributes 10% towards wagering. Every £10 bet counts as £1 in wagering.

Restricted games are most often those which have an extremely high RTP (return to player). If the game is likely to give you back what you put in, the casino doesn't want you playing it.

Winning caps

The maximum amount you can withdraw even if you won more

The winning cap is not a common term but it can show up, especially when a casino has a generous free spin offer. The winning cap is the maximum amount you can withdraw from that bonus regardless of how much you won.

The winning cap is one of the least-liked bonus terms among players. It removes the possibility of you winning big.

Some rare casinos will also cut your free spins short if you have already reached the cap. For example, if you are awarded 100 spins with a £20 cap, and you win those 20 pounds on your first ten spins. Then those last 90 spins will be removed and you just get to keep the £20.

Minimum withdrawals

Casinos can put limits on how little you can withdraw

As with deposits, also handling withdrawals costs casinos money. Besides, they'd rather see you playing that money instead of taking it home just yet. That's why casinos have a minimum withdrawal limit.

As a UK player, you have the right to withdraw your real money balance at any time. However, if your withdrawal is below the minimum threshold, the casino can charge additional handling fees. These can be several pounds, which makes the fees swallow up a large portion of your withdrawal.

In the past, players were able to reverse a withdrawal and essentially play with any money they had previously decided to withdraw. During the COVID-19 pandemic, the UK Gambling Commission prohibited reverse withdrawals. This measure aims to prevent players from betting away their winnings after they've requested a withdrawal.

Excluded banking methods

Deposits made with certain payment methods don't qualify for the bonus

It is very common for casinos to restrict some banking methods from deposit bonuses. eWallets like Neteller and Skrill are often listed as methods that can't be used to collect bonuses. Also, PaysafeCard is occasionally on the exclusion list.

There are a couple of reasons behind these restrictions. One is that eWallets offer the players slight anonymity, which is against KYC regulations. Your personal bank account or debit card is easier to connect to you and to know that it is really you using it.

eWallets have been often connected to bonus abuse. Players have used them to find loopholes in the terms and increase their chances of profiting from the bonuses.

Forbidden strategies and irregular play

If you abuse game mechanics, your bonus will be removed

Casinos often outline betting strategies that are explicitly forbidden in the bonus terms and conditions. Here are the most common ones, and even though not every casino bans them, you should be aware that using any of these strategies can be interpreted as foul play by casinos at their own discretion:

With all these rules and restrictions, you might wonder if the casinos actually enforce them. Online casinos can and will fall back on the option of a strict interpretation of their T&Cs: if you break the rules even slightly, you lose your bonus money, deposit money and any winnings. It's a scenario you definitely want to avoid!

That said, casinos might overlook minor infractions clearly made in error. You might get away with a single larger bet than the specified maximum if you immediately tell customer support about it. Also, accidentally playing a few rounds of a wrong game might not result in you losing everything. However, casinos won't let anybody gain an advantage from their kindness and will at least deduct the ill-gotten gains from your winnings.

Casino bonuses and responsible gaming

The first thing you should remember is that online casinos are businesses, and are here to make money. You might be familiar with the saying 'there is no such thing as a free lunch', and this is definitely something that applies to casino bonuses as well.

Bonuses can be worth your while if you study the bonus T&Cs well and have done your homework, knowing what wagering requirements mean and what limitations you'll have if you decide to claim a bonus. However, bonuses aren't exactly free - not even no-deposit bonuses. Casino bonuses are solely for attracting new players, or to keep people playing longer.

Hunting for bonuses and trying to complete wagering requirements can be fun, but it also might create an unhealthy environment. Gambling can become addictive, which is why we recommend you pace yourself and always use the responsible gambling tools provided by the casino. Set deposit and/or loss limits, be aware of the time passed and don't gamble more than you afford to lose.

Bojoko is a strong advocate of responsible gaming. Please read our article on responsible gaming to find more helpful information.


The most sought-out casino bonuses are no-deposit bonuses that don't require deposits. The customer only has to register a new account with the casino and follow the steps provided by the casino.

Check out our list of casino bonuses to see the top offers at the moment.

Once claimed, a casino bonus is added to the player's account balance. From there, the bonus money can be used like you would use cash - to play games and place bets.

Do be mindful of the bonus terms and conditions, however, as there usually are some limitations to how much you can bet per spin with an active bonus and so on.

Many UK-licensed online casinos use bonus codes to unlock casino bonuses for players.

Not all sites require you to enter a casino promotional code to get your bonus. When a new UK casino reviewed on Bojoko features a first deposit or no deposit bonus code, this info is displayed on the listing page. In addition, you can see the bonus codes on our curated casino lists.

An online casino bonus code is a case-sensitive combination of letters and numbers. Use the casino bonus code to redeem a special offer when prompted on the casino website.

You'll normally be requested to input the code when you create an account or make your first deposit. In some casinos, you may need to contact customer support to redeem your code, although this is quite rare these days.

Casino bonuses can be divided into a few categories:

  • No-deposit bonus: A bonus you can get without a deposit.
  • First deposit bonus: A bonus you may claim by making your first deposit.
  • Reload bonus: A deposit bonus you claim after the first deposit bonus.
  • Free spins: Free rounds you can claim without a deposit and use on a casino game.
  • Bonus spins: Spins you may claim with a deposit.
  • Cashback: Money you can get back from a casino, usually calculated from your net losses.

The first deposit bonus can also be known as a sign-up bonus or a welcome bonus.

A first deposit bonus is a bonus type you can only get when you make your very first deposit to the casino. If you choose not to claim it when making the first deposit, the offer will expire and can't be claimed on later deposits.

A first deposit casino bonus can be bonus money, bonus spins, or a combination that has both.

Yes and no. That depends on what you're after.

Bonuses are a paradox. If you play at the casino for the socially accepted reason (i.e. having fun), then all bonuses do the trick. They let you play for longer and enjoy the games.

The bonus T&Cs can vary greatly between casinos, which is why it is imperative that you read them through every time before you claim a bonus.

While bonuses can give you a nice boost and allow you to play longer, the bonus terms and conditions can make it difficult to complete the wagering requirement. Or, the T&Cs may set a limit on how much you're allowed to win.

In short, if you find a bonus type you like and the terms are something you think you can manage, bonuses can be worth it.

You can find the currently available biggest welcome bonuses on our list of best UK-licensed online casinos with first deposit bonus offers.

Making money from casino bonuses is definitely possible. However, bonuses almost always come with wagering requirements and other rules and limitations, which need to be taken into account. Wagering a bonus happens by playing, and gambling always holds a risk of losing.

It's good to remember that, statistically, the longer you play the likelier it is for you to lose.

Generally, no. Bonus funds can only be withdrawn after completing the bonus wagering requirements set by the casino. If you should attempt to make a withdrawal before this, the bonus and any funds won with the bonus are usually removed from the account balance.

The only exception is a bonus without wagering requirements. Sometimes you can even get a no-deposit bonus with zero wagering, but note that you need to have made at least one successful deposit to the casino before.
