We strive to bring you the most current and best slot sites and games all through the year at Wizard Slots. Because this market is constantly evolving, we do all the hard work for you rather than testing hundreds of online slots with a bonus. Here at Wizard Slots, we strive to provide you with all the information you need about slots. That includes bonuses, how they work, and which one is right for you.

We can help you find the bonus slot selection you want, whatever it may be.

Defining Online Slots

More than 70% of all casino games online are slots. As a result, the number of players interested in slot machines has soared in the United Kingdom, making slots bonuses more popular than ever. The attractive designs, unique features, classic layouts of these games and even the deposit bonus or welcome bonus allow them to attract players. 

Since the days of one-armed bandits, slot machines have gone through radical changes in design and appearance.

Moreover, they remind players of those in land-based casinos. In a sense, they're nostalgic. However, unlike land-based casinos, online slot games come with slot bonuses such as a welcome bonus as an added benefit. Furthermore, online slot machines are more convenient than land-based casinos. The convenience of online casinos enables you to play anytime, anywhere.

First Deposit Slots

First deposit bonuses, welcome bonuses, and other offers can be confusing and overwhelming, especially for new players. Your deposit amounts may differ depending on the promotion and the operator you use. When making the first deposit, make sure you transfer the required amount. For example, if a minimum deposit of £10 is required, you must deposit £10 or more, but no less.

If you pay less than the required minimum deposit amount, you will miss out on the opportunity to claim the welcome bonus because you would not meet the minimal requirement. Just like there is a minimum deposit, there may also be minimum and max withdrawal amounts.

Generally, very few promotions have a specific withdrawal amount. However, most online casinos will impose a minimum deposit before withdrawing anything. Withdrawing your bonus winnings without recognising this requirement might disqualify all of your free bonus spins and your bonus funds account. 

We encourage you to read your online casino's terms and conditions before attempting any transfer of funds.

Bonuses for Existing Customers

Existing customers are also often eligible for casino bonuses.

These bonuses include reload bonuses, free spins and double bonuses, and rolling over bonuses.

However, existing customer promotions have more flexible terms and conditions than a new customer deposit bonus.

Bonus Offers and Wagering Requirements

There may be restrictions on payment methods for deposit bonus offers. These restrictions are called wagering requirements and other terms and conditions. There is nothing as frustrating as wagering requirements when you're claiming your welcome bonus. However, this is only true if you did not read your slot bonuses casino's T's and C's

It's essential to read up about wagering requirements as they rule most slots bonuses, deposit bonuses, and free spins winnings. To withdraw your free spin winnings, there is a deposit required.

Here is an example: Let us assume that you discover a casino with online casino bonuses offering a £100 bonus for new customers. Terms and conditions state that wagering requirements are 10x. 

How Does Wagering Requirement Work?

The wagering requirement essentially requires you to wager ten times your deposit amount before withdrawing any funds, including your bonus money. So essentially, you won't be able to withdraw your bonus wins from your bonus slots until you've deposited and played through £1,000 first.

Furthermore, other casinos also use what is called a game weighting rule. Blackjack, for example, could count toward your wagering requirements, but poker might not. All in all, there are wagering requirements attached to most casino deposit bonuses in the UK; however, many of them are very affordable.

Online Casino Free Spins

We're willing to bet that the free spins offered by casinos online are part of the reason why online slots are so popular with players. The deposit bonus and deposit requirement for a free spins promotion are usually not too high, nor is the wagering requirement. However, there are some restrictions.

In many cases, free spins are offered only for certain games. For example, such a promotion might look like this:

"Get 30 free spins when you deposit £10. You must use the spins within seven days after receiving the bonus (Terms and conditions apply)." This offer means that for every £10, you will receive seven free spins, but they are only valid for seven days. Additionally, these free spins can only be used in specific games.

As a general rule, free spins cannot be redeemed for cash. However, winnings from free spins can be withdrawn as cash funds in most cases. Be sure to review the offer's terms and conditions.

What Makes Online Slots Popular?

The popularity of online slot machines has been attributed to several factors. As we have mentioned, some of these factors include a deposit bonus, welcome bonus, and other casino bonuses. 

Let's look at some overlooked slots popularity factors:

  • Slots can be played without any skills. A slot machine's outcome is entirely determined by luck. Unlike games like blackjack or video poker, you don't need to have some calculated strategies up your sleeve to succeed. As a result, slot machines have a much broader appeal.

  • The packaging is appealing. Modern slot machines are based on themes. They are often themed around fantasy movies, Mythology, food, video games, and the entertainment industry like celebrities. Also, the gameplay is enhanced by symbols, graphics, and audiovisual effects. The variety is so great that you can easily find subjects of interest to you.

  • Gaming Features: With slots, adding novel gaming elements is far easier than with other casino games. New games tend to have something unique like a distinct wild symbol, a dramatic reel structure, multi-level bonus feature, etc. Everything is constantly changing.

How do Slot Machines Work?

Slot machines were initially electromechanical devices. However, slot machines are now controlled by software in both land-based and casinos that are online. In slots, a random number generator (RNG) determines the symbols that appear on the reels. That means the entire process is fair, and there is no chance of cheating. 

To ensure that the software uses a random number generator that is impartial and random, independent experts periodically test the RNG. Then license and regulatory agencies ensure that casinos and players cannot alter or modify the software.

Lastly, every slot machine game is observed and compared to a theoretical projection over a given time.

Other operational functions of a slot machine are bet placing and the withdrawal of winnings.


The most common method for determining the total bet on older slots was to select the coin size, the number of coins required per payline, and how many paylines are there. Depending on your bankroll, you can bet smaller or more coins per payline. These elements are combined to simplify the playing experience in the newer slots.

Winnings payouts

Once you place your bet, click on the Spin button. The machine will take your wager from your balance. At the end of the spin, there will be a final arrangement of symbols. If you get lucky and land a winning combination of symbols, the machine will automatically determine the payout.

The amount you win will either be an absolute number or a multiplier. Your account will be credited with the winnings if any. Please remember that your payout may be less than your total wager, depending on the number of possible winning combinations.

When you play slot machines at your favourite casino, free spin bonuses can give you that extra boost to help you win real money. However, not all bonus spins are the same. We've listed the different types of bonus spins below, so you can decide which is for you.

Does it Matter How Much You Deposit at a Slot Site?

There are usually limits to how much you can deposit in most casinos. A minimum amount is set for them, usually between £5 and £10. However, most casinos will allow you to make as many deposits as you need, even if some state that you can only deposit a certain amount per payment method.

Additionally, you will be limited in the kind of payment method that you can use. The highest limits tend to be in debit cards and bank transfers, while e-wallets and online payments tend to be lower. The highest limits tend to be in debit cards and bank transfers, while e-wallets and online payments tend to be lower. There are several popular ways to play with including:

It's important to note that in some casinos, bonus funds expire.

Online Slots With Free Spin Bonus

As one of the best online casinos in the UK, Wizard Slots is bursting with slots that come with bonus spins. The following are some of the most favourite slots with bonus spins:

Starburst: In 2012, NetEnt developed the wildly popular Starburst slot machine, and the game has since become a big hit with online gamblers everywhere. It's a fantastic video slot with five reels full of brilliance and winning chances.

The game features a high RTP of 96.1% and x250 single-win maximum and expanding wilds that trigger re-spins. In addition, you can enjoy up to 500 free bonus spins on Starburst as a new Wizard Slots member (Full terms and conditions apply).

When you play the Starburst slot, you will be able to experience fast-paced and exhilarating games with an array of exciting features that make your experience memorable.

Gonzo's Quest: An animated Gonzo and engraved stones provide some personality to this jungle-themed game, featuring six reels and engraved stones. You can choose between various coin values and betting levels on this online slot.

Although the game has only 20 paylines, we've discovered that landing a 5x multiplier during an Avalanche tends to give you the best odds of hitting the big time. In the bonus round, you can also score some excellent rewards.

The Gonzo's Quest slot has quickly become one of Net Entertainment's most popular titles.

Ghost Slider: Players can find something different about this online slot game's gameplay compared to other types of slots. Unlike other slots, a winning combination is formed when the reels collapse. Symbols from the top are then removed, and the process repeats until no more wins are achieved. It is a fun feature not found in other online slot games.

If you land enough winning combinations in this game to trigger the free bonus spins, you will see a skeleton above the reels booting one of the gravestones to the right-hand side. The Ghost Slider is sure to be one of your favourites if you enjoy ghosts and ghouls.

In Ghost Slider, gravestones roll across the top of the reels as you play, adding a bit more creepiness to the gaming experience, as well as serving the purpose of providing additional entertainment. Additionally, a creepy house, a clock, a spellbook, and a vintage style candelabra appear behind the reels to give you a sense of gloom and doom.
