There are two main criteria that for the team here at BookiesBonuses, separate the very best casino welcome bonuses from the rest.

1. Bonus Value: Which bonus gives you the most bang for your buck? The best bonuses at least match your deposit in bonus funds while the best bonuses don't even require a deposit.
2. Bonus Conditions: Which bonus is the easiest to turn into real money? The best bonuses have no wagering requirements, no max win amount, no expiry, and no restricted games i.e. you can use your bonus money how you want to.

If that didn't make sense to you, we explain how to understand and evaluate the T&C's of casino bonuses here.

What Should I Look For In a Casino Bonus?

Fundamentally, there are a couple of simple decisions to make before claiming any casino bonus. 

Identifying whether you want a casino deposit bonus or free spins is important, as this will affect the bonus terms and conditions. Deposit bonuses tend to have higher wagering requirements, compared to free spins, but have less limitations on where you can play. 

Another thing to consider is your initial bankroll. if you were to deposit just £10 and you get a 200% bonus, then happy days, but if you are deposit a significant amount and receiving a small percentage bonus, it could advantageous to go elsewhere. 

Ultimately, decide how you want to play and then shop around with this in mind, it will save the hassle of signing up to a bad casino offer, as our expert Del Pugh can testify!!!

Casino deposit bonuses aren't as common in sports betting in the UK as they are overseas, but when it comes to both UK and US 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.

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, Fishin' Frenzy, 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.

No Deposit Free Spins usually come with a higher wagering requirement than regular Free Spins bonuse

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.

There is more chance of you finding the secret to eternal life, than finding a player who doesn't like no deposit free spins!

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 several, including Paddy Power and Sky Bet Casino.

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.

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.

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.
