Get your Top Online Casino Deal

If you’re new to the world of online casino gaming it can sometimes be tricky to choose the right online casino. One thing that many online casinos do to tempt new customers to sign up with them is to offer welcome bonuses. These sign-up offers can sometimes seem very lucrative and generous, but all have terms and conditions attached to them.

So if you’ve been looking at top online casino sites and wondering which has the best bonuses, here is where we can help. If you’re looking for a top online casino in UK then an important part of assessing their worth is the type of promotional bonuses they offer. Here in this article we’ll give you some seriously good advice about how to select the best possible offer from the hundreds of casino bonuses that are out there.

How to Find the Best Deals from Top Online Casino Sites: 7 Important Factors

So if you’re looking for a top online casino in UK how should you start? Well, we think that one of the most important things to check is the quality of the bonus offers. In this next section of this article we’ll take a closer look at seven things that you should consider when you are assessing whether or not to accept a casino’s welcome offer and sign up for an account.

Assess the Generosity of the Offer

The first thing that you should be looking at is the generosity of the offer. Most casinos will offer some kind of matched deposit bonus to tempt new customers in. A matched deposit bonus is where the casino will give you bonus credit worth the same as the initial amount that you deposit in your new account. This will be up to a certain limit, so you cannot just deposit unlimited funds and expect an unlimited amount of bonus credit in your new account. The limit is usually up to £200, though this varies considerably between casinos.

Some casinos will also offer a three-stage matched deposit bonus. This means that you can get an additional bonus for your second and third deposits in your new account. These will often be smaller than the first amount of bonus that you can claim. If you are astute, though, you can pick up a lot of bonus credit from this type of welcome offer.

One thing that you do need to be aware of, though, is that casinos will attach something called ‘wagering requirements’ to a bonus. This means that it is impossible for your bonus credit to be withdrawn as cash straight away. We’ll tell you all about wagering requirements next.

Check the Wagering Requirements

It is really important that you always look at the terms and conditions of a welcome offer before you commit to signing up for an account at an online casino. Wagering requirements are the amount of times that you need to wager the bonus amount before it can be turned into actual cash and you are able to withdraw winnings.

Wagering requirements are usually around the 35x mark, which means that you have to bet your bonus amount, and often the bonus amount that is associated with it, 35 times before it can become cash. Many operators will also impose a time limit on meeting wagering requirements – sometimes as short as a week but more likely to be a month.

If you do not meet the wagering requirements within the allotted time then you will forfeit all of your bonus credit. You can also lose all of the winnings that playing with you bonus credit as a stake generated. This is why it is so important to make the right size of deposit in your account too.

Deposit the Right Amount in Your New Account

If you want to make sure that you gain the most possible benefit from any welcome bonus that you accrue, it is really important that you deposit an appropriate amount in your new account. Yes, you need to deposit enough to ensure that you receive the bonus, but you do not need to be greedy. After all, if you do not think that you will be able to hit the wagering requirements in the requisite amount of time then there is little point in depositing the maximum possible amount.

Instead, you should check the minimum and maximum deposit amounts, weigh them up against the wagering requirements, and deposit an amount that you think fits with your needs. If you are not an especially committed casino player you do not need vast amounts of bonus credit. If you deposit too much in your new account then it could take too long to meet the wagering requirements and you could end up with nothing in your account at all.

Are There Any Additional Extras?

Another thing that online casinos will often attach to their welcome bonus offers is some free spins on a certain range of slots or table games. You can often pick these up as part of a welcome offer that may offer you up to £100 of bonus credit plus 50 free spins on a certain game. The number of free spins will vary from operator to operator.  They are often for games from a certain software developer, so always make sure that you check this.

These are well worth looking out for as they provide you with a nice additional boost and the chance to win some actual cash. These free spins do not often have wagering requirements attached to them like the matched deposit bonuses, so they can be quite lucrative if you manage to enjoy a bit of luck. The top online casino sites are always looking to gain an edge over their competitors, and additional extras like free spins on slots or free spins at the roulette table are a nice additional bonus to pick up.

Enquire at Customer Services if Necessary

If there are any queries you have about your bonus offer you should be able to contact customer services at your chosen operator pretty easily. If you have any issues at all with the bonus then customer service should be willing to help you iron them out. This also allows you to test just how good the site’s customer service team actually is. If they are reluctant to answer your queries, you should probably give them a miss.

Look for Offers for Established Players

As well as a decent welcome bonus, a top online casino in UK should be able to keep its more established customers happy with a generous range of ongoing promotional offers. If an operator does not think it worthwhile to help out its established customers with some bonuses now and again, it should leave you asking a few questions. There should at least be a good loyalty bonus programme where you can pick up some extra perks and prizes now and again.

Check the Overall Range of Services

If you’re looking for a top online casino in UK, you should also look at more than just its promotional bonuses. While these are important things to consider, you should not neglect other aspects of the operator’s services. Always look at the range of games on offer – there should be a varied and interesting selection of slots, table games and other options such as bingo. There should also be a sports betting page, so that you have the full range of options available to you at any time.

The greater the variety of services that an online gambling site can offer the better it will tend to be all-round. After all, if you are spending real money playing at top online casino sites, you don’t want to get bored. Variety helps to keep things entertaining and exciting.
