What Is A Casino Bonus?

A casino bonus is a promotion provided by the online site, for both new and existing players.

At legit, we inspect all bonuses to be sure that the promotion offers value, or if it is more of a gimmick.

We should point out that on this page we are speaking about bonuses offered by the online casino, as opposed to in-game bonuses on slots or games.

There is a big difference between the two as in-game bonus rounds will apply wherever you play the game, whereas casino offers are specific to the site.


Are Casino Bonuses Safe?

Safe Casino Bonuses
safe casino bonuses online
LicenceUnited Kingdom Gambling Commission (UKGC)
Secure log-ins2-step verification, touch ID
PrivacySecure Socket Layer (SSL)
RNGeCOGRA or other certificate
Responsible gamblingDeposit limits, self-exclusions and more
Customer supportLive chat, email, faqs

So long as the online casino that you’re playing at is legit, the bonus will be too. This is especially true for sites that hold a licence with UKGC.

By holding the licence, companies are committed to adhering to strict rules and are subject to punishments if they do not. A part of this falls on the advertising of bonuses, and how clear the terms of offers are.

All of the online casinos we have reviewed are legit, and as such, you can rest assured that the bonuses are safe.

casino bonuses trusted organisations 

What Is A Good Casino Bonus?

As mentioned, knowing how to identify if a good casino bonus is key.

We’ve listed some of the best bonuses above, but even those have terms attached. In order for it to be a good bonus, terms must be fair. Here’s what we recommend you look for:

Fair Bonus Terms
Average welcome bonus amount


Average deposit welcome boost


Average wagering


Free spins wagering

0 – 25x

Payment restrictions

E-wallets often ommited

Time limits

7-30 days

Game contributions

Not all are equal

On-going bonus wagering


Deposit Amount: There will be a minimum amount you need to deposit, but how high or low this is set can affect how good the bonus is.

Percentage of boost: Some casinos will offer you up to 200% while others can be as low as 10%. The 10% will not likely be for a welcome offer.

Time limit: Is there a reasonable time frame for you to meet the wagering requirements? This can be anywhere between 7-60 days.

Wagering requirements: This indicates how much you need to play before you can withdraw. This can range from x25 up to x60 so it’s important to know what you’re getting in to.

Payment method restrictions: Not all payment methods will be accepted, and this is true for almost all online casinos. Make sure there is a payment method you are comfortable with before taking part.

Maximum winnings: Winnings can be capped on bonus money, or with free spins. With 888Casino their cap for no deposit bonus is £500 which is very generous. However, this will usually be much lower.

Games contribution: Not all games count as equal when wagering through a bonus.

Key insight: A bonus is only good if it suits your gameplay, if a £20 minimum deposit is too high, then you may want to look at a different promotion.

Casino Bonus – Key Terms

This is where it can interesting, and usually sorts the good, legit casinos from the scams. We look at a number of restrictions that can occur even before you take up an offer.


Wagering Requirements on Casino Offers

This is the big one and one that many players find difficult to understand. The good news is that legit casino make the requirements crystal clear, so you should know exactly what you need to do.

Wagering requirements are added on by online casinos sites. You will not be able to withdraw winnings from bonuses until they are completed. The best way to explain this is with a live example.

The Unibet casino bonus offers players the chance to get a £40 casino bonus when they deposit £10. The only requirement is to deposit and opt-in. The bonus is then applied. The wagering requirements are 35 times.

Unibet wagering

  1. Deposit £10 via an eligible method to get a £40 bonus
  2. Play through the £40 x 35 = £1,400 within 30 days
  3. If/when wagering is met – you can withdraw any winnings
  4. Bonus and associated winnings will be void if 30 days pass

Therefore, in order to withdraw you need to wager 35 x £40 = £1400. If you take money before then all the bonus, and associated winnings will likely be void.

The £10 you put in is still safe, though. In fact, you will play with real money before the bonus money. If you win with this and take your winnings then you forfeit the bonus though.

You should also look out for what needs to be wagered. Sometimes it is only the bonus amount, but it can also be the bonus + deposit amount. This is why we always suggest checking the terms first.

Key insights: The average wagering requirement is 35x. Anything above that can be considered high, and conversely below is great.

Minimum Deposit

Before you even think about taking a casino offer, check out the minimum amount you need to deposit to achieve it.

A minimum deposit amount is usually £10 but can be £20 with certain brands. It’s something that can prevent you from claiming an offer, so do double check this.

Key insights: The minimum deposit to qualify for a new customer offer is usually set at the sites minimum deposit amount in general while existing player promotions can be higher.

Payment Methods

Payment methods are one of the main restrictions when it comes to claiming bonuses.

The likes of Skrill and Neteller are almost never included while using a debit card pretty much guarantees you’ll be eligible.

At legit, we like PayPal and Apple Pay as they offer an extra layer of security when depositing. The good news is that many online casinos are starting to accept those as part of offers.

It’s important to check what methods are eligible for bonuses to avoid depositing only not to be able to claim a bonus.

This is something that an online casino should mention in their key terms, but you may need to examine the full terms for details.

Maximum Payouts

A maximum win amount is usually imposed on free spins or a bonus. It means that the online casino can limit their loss. But that doesn’t mean that you are not able to win.

Across the best online casinos, the average is around £100. Although, in saying that, some sites do go up to £500.

Jackpot slots are also usually omitted. This means that it might not be worth playing jackpot slots with your casino bonus.

Key insights: Not ALL casinos will put a limit on what you can win. Details will be in the terms of the offer, so we recommend checking before depositing.

Time Limits

These can occur before you’ve deposited. Once you’ve registered your account, you’re likely only going to have on average 7 days to claim an offer.

On top of that, once you’ve deposited there will be another time limit and a limit on when wagering must be completed by.

This might seem frustrating, but casinos change bonuses often so it’s to ensure you get the one you’ve signed up for. Furthermore, the bonus is given as a means to attract players to play, so this is a way of ensuring that occurs.

Of course, time limits also apply to existing bonuses, but again this will be to do with how long the campaign is running.

The moral here is that if you want a bonus, you should take and use it in a timely manner.

The best online casinos provide fair bonuses but discover what else makes an online casino legit with our guide. Best online casinos

Game Limits

This is with reference to where you can complete the wagering of a bonus. Ther term ‘not all games are equal’ means that not all games contribute 100% to the wagering.

Game Contributions
Bonus AmountWagering RequirementContributionTotal to Wager

As you can see, this can have a huge impact on how much you need to wager through. Roulette and Blackjack tend to contribute around 10% at most online casinos. Therefore, you might want to avoid those whilst completing a bonus.

It is also likely that some games or slots won’t contribute at all. A list of game limits will be listed clearly in the terms, so be sure to check those.

Stake limits are also applied. So you won’t be able to play massive stakes at once, on slots or table games.

Online casinos want you to play through your bonus quickly, but with low stakes. Don’t let this put you off, it is a bonus after all.

Key insights: Typically slots will contribute 100%, but those with a high RTP may be excluded.

Types of Casino Offers

There are so many different types of bonuses with sign-up offers being the most attractive. You’ll likely be able to take up a deposit boost to start with, with free spins often on offer too.

It’s not only new players who can take advantage of the best casino offers though.On-going promotions can be valuable for existing customers.

While all this is great, it’s important to remember that each promotion comes with a strict set of terms and conditions.

Let’s take an in-depth look at what offers you will come across, their value and the pitfalls to avoid.

Welcome Bonuses

The most valuable bonuses given by online casinos are undoubtedly welcome promotions.

These usually provide players with the chance to gain extra on their first deposit, and may also include free spins.

The best casino bonuses for new players will offer a 100% boost which is effectively double your first deposit. Although this is not a guarantee.

Some online casinos also do not require you to make a deposit to qualify. With 888casino for example you simply need to register for an £88 bonus.

Picking the right welcome bonus can be tricky, especially with so many terms to consider.

Our advice here is to take a bit of time and make sure that the bonus is for you, and to read the terms.

You can also check out our top casino offers picks from above which have all been tried and tested.

Free Spins

This type of offer has a huge amount of appeal for players because it tends to be exactly what it says – free spins.

An online casino may offer free spins as part of their welcome offer. It doesn’t tend to form the entire promotion though, as they provide excellent value to the player.

They can also be awarded as a play and get the reward. For example, play 50 spins on Starburst to earn 10 free spins.

Or they could be given as a loyalty reward. The good thing about free spins is that they can often come with no wagering requirements. This makes them better than other offers because what you win, you can keep.

From a legit point of view, they offer a good way to try out a game or get rewarded for playing on your favourite.

Key insights: These are not to be confused with free spins within bonus rounds of slots.

No Deposit Bonus

Sadly, these are becoming less and less popular. Not least because there are so many rules that UK casinos need to follow. Handing out no deposit bonuses can be tricky because a casino won’t yet have verified an account.

Of course, while they are rare – they are great. They offer money for nothing or free spins for nothing and we would certainly recommend snapping these offers up. The likes of LeoVegas and 888casino both offer these, so they are not unheard of.

Key insights: Bear in mind that you may need to deposit in order to be able to withdraw, and be prepared to verify your identity too.


Deposit Bonus

Unlike the no deposit bonus, deposit bonuses are very common. You’ll find our welcome bonus section littered with these types of promotions and this extends to existing promotions too.

There’s more to these bonuses than meets the eye, and they can vary widely. A typical welcome offer is a 100% match, which means doubling your first deposit.

The maximum amount and wagering requirements are different across sites. It’s important to pick a good mix of these, as they can make bonuses unachievable.

For example, if you are offered up to £200 but wagering is set at 50x, would you realistically meet the £10,000 playthrough required?

A smaller bonus of say £50 at 35x wagering would mean a playthrough of £1,750 which could in fact provide more value as it is able to be met.

Reload Bonus

This is a term you will see thrown around quite often. It is effectively the same as a deposit bonus. This is for existing players only as the reload part might suggest.

They may also be regular loyalty bonuses that are offered weekly.

For example, if you deposit on a Friday, get 10% more than you deposit. They are worth looking out for.

In our experience, these types of offers are a good way to increase your bankroll. But if the terms aren’t favourable, they might be best left alone.

Key insights: These won’t be open to all players, so you may be asked for a bonus code. In order to increase your chances of receiving these offers, we recommend opt-ing into marketing communications.


Cashback is a useful offer and one which is often overlooked. It can be used in both sports betting and online casinos and gives players a percentage of their losses back. While it doesn’t sound very appealing, it is.

For example, an online casino might offer you 20% back on net losses. They will provide this for losses:

Daily play – 24 hour period
Weekly – Usually set from Monday – Sunday
Monthly – Over an entire month
Game specific – losses on a certain game in a set time period

You will then receive either a bonus or cash for that amount.

But bear in mind a maximum amount will be applied; 20% up to £50 is normal.

If you receive a bonus then wagering will be applied, so be sure to check the terms.

On the odd occasion, you might even get cashback on your winnings – which is an interesting twist.

Key insights: You should be able to see all of your gameplay in the history section of ‘my account’; from there you can work out your net losses. This is usually based on deposits – withdrawals over the time period, but sometimes overall stakes in that time could be used.

Live Casino Offers

Some online casino sites will separate their live casino bonus from their casino bonus.

The downside to this is that it can mean that all live casino games are illegible as part of your casino bonus wagering. Or that if it is included, they will be restricted in terms of game contributions.

The advantage to players for having a bonus for each product is that you can sometimes claim both bonuses.

So, if you prefer to play on live tables with real people, there is likely a live casino bonus you can get.

Key insights: In our experience, live casino bonuses tend to offer lower deposit match amounts.

VIP and Loyalty Bonuses

Apart from the bonuses mentioned above, players can also take advantage of loyalty rewards. These can come in the form of a detailed programme or can be off the cuff, it really depends on the casino.

VIP rewards schemes tend to be more well-advertised as players make their way up to levels. Not all online casinos offer these, and they are in fact becoming less common in the UK especially.

Other VIP benefits may include:

  • Faster payouts
  • Birthday bonuses
  • Free entry to exclusive tournaments
  • Higher deposit and cash out limits
  • Invites to exclusive events

We should also point out that they are less common in the UK because of laws. It is important that players aren’t encouraged to play for rewards. So, don’t wager more than you can afford in the hope of reaching the higher levels.

If you do think that you may have an issue, there are many sites that can help including
