Casino Bonus 2021

Claiming the welcome offer at any casino site is one of the most exciting aspects of online gaming, and fortunately, most online casinos have excellent bonuses for new players to take advantage of.

Bookies Bonuses is primarily a sports betting site comparison platform, but we also dabble in casinos and many of the bookmakers that we are partnered with also have fantastic casinos on offer.

The rankings of the casino bonus offers below are not solely based on the bonus amount (that would be too easy!) but instead determined by a variety of factors.

They include the wagering requirements, variety of games, overall casino site quality, and functionality and flexibility surrounding both the bonus offer and the casino site.

Some of the best offers are from sites that have been around for many years, while others are new casino bonus offers.

Deposit bonuses aren't as common in sports betting in the UK as they are overseas, but when it comes to casino bonuses, deposit bonuses are by far the most popular.

Most first deposit bonus offers within the online casino space are 100% up to your deposit, but the bonus will be capped at a maximum amount - usually between £50-£200.

If you claim a 100% first deposit bonus, deposit £50, and lose that money, you'll have that £50 bonus to fall back on.

Winnings from such bonus offers will be subject to wagering requirements, and this is one of the most important things to look out for in casino bonus terms and conditions.

How to Claim a Casino Deposit Bonus

1. Select a deposit bonus from our list of best casino bonuses.
2. Register and verify your account.
3. Make a deposit and claim the bonus.
4. Play through your balance, and then your bonus if necessary.
5. Complete wagering requirements if bonus money is used.
6. Once wagering is complete, you are able to withdraw your balance.

It is important to note that your real money balance will be used before your bonus balance unless otherwise stated. That means that you cannot simply make a deposit, claim the bonus, and then withdraw your initial deposit straight away.

Besides the first deposit bonus, many online casinos offer free spins to new players. Often, the free spins are offered on a specific slot machine - usually a new or promoted title. 

Popular slot machines for free spins include Starburst, Gonzo’s Quest, Warlords, and Mega Fortune Dreams.

At some online casinos, you can get free spins or casino free bets just from registering a new account. These casino free spin no deposit offers are very popular among recreational players. It’s a good way to test out a new casino without risking any of your own money.

Most online casinos (but not all) have a wagering requirement attached to any winnings accumulated from the free spins, and that's why it's important to always compare the terms and conditions.

In other instances, you may be required to deposit and perhaps even wager some money before unlocking your free spins.

Then, there are free spins that come as an added extra in a deposit bonus offer. So, in summary, the main possibilities when it comes to free spins offers are as follows:

• No deposit free spins
• Bet money and get free spins
• Get free spins on top of your deposit bonus
• Existing customer free spins

Free spins will have an assigned value on them, and it is usually £0.10. So if you get 100 free spins at £0,10, it is essentially a £10 bonus.

Free bets are more commonly associated with sports betting rather than online casino, but parallels can be drawn between the sports free bet offers you might receive and the various casino deals you can claim.

Even if most casino bonuses are not marketed as 'free bets', lots of them are essentially free bets when you consider what they actually consist of.

Free spins are similar to free bets, and the same can be said of any 'Bet & Get' style offer on an online casino site.

You can get casino free bets for slots or for table games such as blackjack or roulette.

The well-known blackjack variation, Free Bet Blackjack, is not a free bet promotion. It is just a version of the game that involves free bets on splitting pairs and doubling down.

No deposit casino bonuses are everybody's favourite.

Why? Because you don't have to spend any of your own money, of course!

But that does not necessarily mean that they are the very best overall. Obviously, not having to add funds to your account is a huge plus, but the wagering requirements on these deals can be much more difficult to play through than those on standard deposit bonus offers.

Also, your winnings on no deposit casino bonuses could be capped, which is much less likely to be the case with deposit bonuses.

Still, if you enjoy playing casino games, then you are hardly going to turn down the opportunity to claim a no deposit casino bonus and potentially win some cash.

These offers are rare, but that is not to say that they don't exist. In fact, you can claim one below.

You would be forgiven for thinking that all of the casino bonus fun is over once you've claimed the welcome offer(s) you want, but that couldn't be further from the truth.

Of course, attracting new customers is key for online casino sites and that's why they have welcome offers, but retaining those players is also crucial, so existing customer promotions are also offered regularly by the best casino bonus sites.

While welcome offers are almost always deposit bonuses and/or free spins, casino sites are able to be a lot more creative with their existing customer promotions.

As well as conventional promotions, there may also be opportunities to secure a share of a prize pool in tournaments, or even win a holiday or something of that nature.

Best Casino Promotions

• Deposit Bonus - Commonly seen as a welcome offer, but similar deals can also be offered to current players.
• Reload Bonus - These deals give players the chance to scoop a bonus on a specified day by depositing money into their account.
• Free Spins - Existing players can often grab free spins as part of promos that casino sites run.
• Refer Your Friend - Get a mate to sign up to a casino site and you'll both be rewarded with a bonus.
• Lucky Spin Tournaments - Take part in a slots tournament and potentially win a large cash drop.
• Cashback - Get a percentage of your money back if certain stipulations are met.
• Prize Pools - Online casinos can implement prize pool promotions in a wide range of ways.

While some operators keep the same casino bonus for years, others like to mix things up and give new players different options from time to time.

Even those who keep their welcome bonus the same may pop up with new bonuses for existing players.

There are also lots of new online casino sites entering the market and therefore lots of new bonus options for those players that like to hop from one casino to the next, claiming all of the best bonuses along the way.

With lots of products and services, terms and conditions are somewhat irrelevant and you'll just skip through and accept them without thinking twice. But with online casino bonuses, or any betting offers for that matter, that is unwise.

You don't necessarily need to spend an hour looking through every term on the site, but at least familiarise yourself with the things that will make a difference when claiming your casino bonus.

Wagering Requirements

A casino bonus must be staked a set number of times before a withdrawal can be made - this is known as the turnover requirement or wagering requirement. If a bonus of £100 has a turnover requirement of 40x you must stake a total of £4,000 in the casino before a withdrawal can be made. 

It's important to check the terms of the wagering requirement because often it is the case that table games such as blackjack and roulette contribute a smaller percentage (or none at all) towards the wagering requirement. The wagering requirement must be met within the validity period of the bonus (usually around 30 days).

Eligible Games

You need to check not only which games are eligible for the offer, but also which of them count 100% towards the wagering requirement, and which are worth less than that.

Free spin offers may only be valid on certain slots, while deposit bonuses tend to at least allow you to play on any slot game you wish.

Minimum Deposit

This term indicates the smallest bonus amount you can claim. If it is 100% deposit bonus offer and the minimum deposit is $10, then you can add $10 to your account and receive a $10 bonus. You wouldn't, in this instance, be able to just deposit $5 and get a $5 bonus.

Maximum Bet Amount

You are likely to have to abide by maximum bet rules when using your bonus. So, you cannot just make one large wager and then claim to have completed wagering requirements.

Maximum Winnings

This applies mostly to no deposit casino bonus offers, and it caps the amount that you can win with your bonus money, even if you actually win more when playing.

Validity Period

You may have to claim your bonus within a certain timeframe after signing up, and also complete your wagering requirements within a specified time too.

Payment Methods

Check that your chosen payment method is eligible for the bonus because if the online casino site accepts certain eWallets or prepaid cards, you might not be able to use them for your qualifying deposit in a bonus offer.

Debit cards are usually always accepted, while PayPal varies and most other banking options are usually excluded.
