Types of UK Online Slots Bonus

These differences can be seen in the welcome bonuses, game contributions, types of qualifying deposit and wagering requirements. Some can only be claimed by players from the UK. And others can only be claimed if played on a mobile phone. Nevertheless, the best online slots bonus offers are extremely advantageous. They can give your bankroll a huge boost, and in doing so, reward you with extra spins.

Best Slots Deposit Bonus Offers for 2021

Probably the most common online slot bonus is going to be the ubiquitous welcome bonus. On the whole, this will come in the form of a deposit bonus. Essentially, this means that the online casino needs your bank information at the very start of your relationship. You’ll need to transfer real cash into your online casino account and only then will you be able to claim your jackpot slots bonus. This is because many casinos like our favourite, King Billy Casino, have cash prizes tied to their welcome bonus. A few years ago, it was possible to find no deposit welcome bonuses, but these days they are gradually falling from favour.

No Deposit Online Slots Bonus Offers

Free no deposit bonuses were once a popular means of attracting new players. So it goes without saying that being able to play at an online casino without first depositing funds into your casino account appears to be a winner. But you need to keep in mind that these free no deposit bonus offers are not going to be the favourite promotion of the casino itself. One thing you’ll notice straight away is that, with these free offers, your winnings will often consist of just free spins. In some ways, this was implemented in order to encourage first-time players to make a real cash deposit. By doing so, the carrot at the end of the stick was the fact that they could win real cash prizes. 

Sometimes it’s possible that reputable online casinos will offer a no deposit slots bonus as a means of a promotion. But it will often be tied to existing players, as a means of rewarding them with some extra spins. You’ll find that this online slots bonus needs to be played on set machines, for example, Rainbow Riches. If there is any real money to win, then, unfortunately, the amounts will be pitifully small.

Best Slots No Wagering Bonus for UK Players

Now that we have covered two popular types of online slots bonuses; the free no deposit bonus and the deposit slots bonus, there’s a third bonus in the online casino’s armoury. This is the no wagering bonus. As you’re well aware, all bonuses come with a number of conditions. To that end, here at, we always suggest that you read through the casino’s bonus terms and conditions. This will tell you all about the wagering requirements, as well as the bonus jackpot games you can use the funds or extra spins to play on.

The no wagering deposit bonus will reward players. This can be with a number of extra spins or a very small amount of bonus funds. You’ll find these spins can only be played on certain slot machines, such as Starburst. The great thing about no wagering bonuses is that if you do happen to have any wins, then you can withdraw these directly. In other words, there’s no need to fulfil the casino’s playthrough requirements. These offers are not so common and they will only be for first time players.

Be Aware Of The Wagering Requirements

As a given, before you accept any type of welcome bonus from an online casino, you should always take the time to read through the slot’s bonus terms and conditions. It’s important that you’re able to fulfil these, as some online casinos will offer such stringent wagering requirements, that fulfilling them is almost impossible.

The Range of Slots

Check out which slots it’s possible to play your online slots bonus through in order to win the jackpot online. The main reason for this is that many online casinos will limit the number of slot machines you can access with your bonus to those with very small payouts. In other words, higher-paying slots will be off-limits for playing through your bonuses.

Online Slots Bonus Terms That Are Fair

terms and conditions

In truth, what one gambler might consider as fair, another might look upon as being the opposite, very unfair. If you read through the online slots bonus terms and conditions, then you’ll be familiar with such things as the validity period, the game contribution, the mineral deposit and the wagering requirements. But just because you’re aware of these, doesn’t necessarily mean they are fair. For example, you can find wagering requirements above 45x going up to 50x and 60x your initial wager. 

To be frank, you shouldn’t attempt to play any online slots bonus with a wagering requirement higher than 30x. Likewise, another question is such things as the length of the validity of the bonus. Once again, some online casinos will allow you up to 60 days to play your bonus through. Whereas others may require as little as just 24-hours to play it through from the point you actually receive it. Providing that the casino in question has a reputable gambling licence, like a UK Gambling Commission licence, then you’ll find all the games to be absolutely fair and above board.

The Minimum Deposits Required

It’s important to check exactly what the minimum deposit will be at any online casino you’re thinking of signing up to. Here at, we suggest that you aim between £10 and £20. On the whole, an online casino that accepts a £10 deposit will only allow you to play on certain slot machines. This is because, as your deposit is relatively low, the casino is concerned that you might win more than you have given to the casino itself in funds. Also, note that with low deposits, you may find the validity period is very short. Conversely, the wagering requirements may be relatively high. Once again, be sure to read the small print before you make your first deposit and place your first wager.

Maximum Online Slots Bonus Amounts Given

It’s only natural that any online gambler who’s scouring the internet for bonuses is going to be looking for those who offer the largest sums. This is all well and good. But once again, be sure to check that the terms and conditions of the online slots bonus. Make sure they are reasonable and fair. Some online casinos will offer spectacular amounts like £500. For example, King Billy Casino offers all new players 151% up to €/$500 plus 51 bonus spins. But you’ll need to be generous with your deposits. With a high deposit from the player, they can be more generous with better offers. Especially on such things as extra bonus rounds, along with at least 50 or more free spins. With huge deposits like this, you’ll find the wagering requirements are more generous as well.

The Maximum Bet Amount When Playing With A Bonus

bet limits

You’ll often find that online casinos will place bet limits during the bonus play period. On the whole, this is to prevent any form of online slots bonus abuse. Subsequently, you may find the sums frustratingly small such as a maximum of £5. But there’s no way around this, as virtually all online casinos will have solid wagering requirements. And the maximum bet amount will be relative to their online slots bonus offers. Mind you, if you’re like most gamblers and a low stakes player then you shouldn’t find this low maximum wagering to be an inconvenience. As a given, good bankroll management requires that you only wager small amounts at a time. In many ways, this will help increase your jackpot winning chances, as you’ll be keeping a tight rip on your bankroll.

Accepted Methods Of Deposits

When you check out the online casino’s terms of service, you may be surprised to find that online slots bonus money needs to be paid using a certain payment method. For example, many online casinos will state that they will not accept e-wallets. These include such companies as Skrill and Neteller. Be careful because they may prohibit you from making a deposit in order to receive a bonus. Yet the crafty casino will still accept a payment deposit. The same follows for payouts.

In real terms, this means that you will not be able to receive an online slots bonus after depositing funds into your casino account. Once again, and be sure to read through the terms and conditions in order to ensure that you’re using the stated and correct payment method in order to receive your bonuses.
