Best slots Bonuses UK

Slots Bonuses vs. Casino Bonuses

Although casino bonuses and slot bonuses are often used interchangeably, they have distinct characteristics that set them apart. Casino bonuses are broader and can be applied to various games within an online casino, while slot bonuses are specifically tailored for some specific slot games. Understanding the differences between the two can help you make the most of your online gambling experience when you play online slots.

Casino Bonuses

Casino bonuses are promotional offers provided by online casinos to attract new players, retain existing ones, or encourage players to try out new games. These bonuses can apply to various types of games within the casino, including slots, table games, live dealer games, and more. Casino bonuses come in different forms, such as:

• Welcome bonus. These are offered to new players upon registering and often include a match bonus, which is a percentage of the player’s first deposit, and sometimes free spins or other promotional offers.
• Reload bonus. These are given to existing players when they make subsequent deposits and are similar to welcome bonuses but usually with a lower match percentage.
• Cashback bonus. These offers return a percentage of the player’s losses over a specific period, helping to mitigate losses.
• No deposit bonus. These are provided without requiring the player to make a deposit and can include free spins, bonus cash, or free playtime on selected games.

Slot Bonuses

Slot bonuses, on the other hand, are promotional offers specifically designed for slot games. These bonuses can be part of a casino bonus package or offered as standalone promotions. Slot bonuses are typically offered in the form of free spins, allowing players to spin the reels of a particular slot game without using their own money. Some slot bonuses may also include multipliers, bonus cash, or other benefits, but the primary focus is on slot games.

Main Types of Slot Bonus UK Offers

Slots bonus UK offers came in many different forms, and new UK slot sites are always trying to come up with new ideas to stay ahead of the competition. In this comprehensive guide, we’ll delve into different types of the best slots bonuses, including free spins, no wager slot bonuses, mobile slot bonuses, and more. We’ll also provide tips on how to make the most of these offers and maximize your winning potential. Let’s get started!

Free Spins Slots Bonuses

Free spins are the most common type of slot bonus and are usually offered as part of a welcome package or ongoing promotions. They grant players a specified number of spins on a particular slot game without using their own funds. Free spins can come with or without wagering requirements, which dictate how many times the winnings from the free spins must be wagered before being withdrawn. Here’s some insight on how to make the most of free spins:

• Look for offers with low or no wagering requirements.
• Pay attention to the maximum cashout limit, if any.
• Check the eligible games for the free spins, as some offers may be restricted to specific slots.
• Use the free spins within the specified time frame, as they may expire.

No Wager Slot Bonuses

No wager slot bonuses are a highly sought-after type of promotion, as they come without any wagering requirements. This means that players can withdraw their winnings from these bonuses immediately, without having to meet any playthrough conditions. These bonuses can include free spins or bonus cash, but the primary advantage is the absence of wagering requirements. Let’s take a look on how to squeeze the maximum value out of a no wager slot bonus.

• Keep an eye out for exclusive promotions or loyalty programs offering no wager bonuses.
• Read the terms and conditions to ensure there are no hidden catches.
• Use the bonus on games with a high return to player (RTP) to maximize your winning chances.

Mobile Slot Bonuses

Mobile slot bonuses are specifically designed for players using smartphones or tablets to access online casinos. Bonuses for mobile slots can include free spins, bonus cash, or other promotional offers, but they are exclusively available for mobile users. Mobile slot bonuses encourage players to experience the convenience and flexibility of playing slots on the go. To make sure you get the maximum possible value out of your mobile slots bonus, you should follow these simple steps.

• Ensure that your device is compatible with the casino’s mobile platform.
• Look for casinos with a user-friendly mobile interface and a wide selection of mobile-optimized slot games.
• Check if the mobile slot bonus is applicable to the browser-based version of the casino or you need to download a slots app.
• Take advantage of mobile-exclusive promotions to boost your bankroll.

Other Types of Slots Bonuses

• Deposit match bonuses. This is applied when you make a cash deposit at a casino. A deposit match is given as a percentage of the amount you deposit, up to a specified maximum. Deposit matches are given on a single deposit, or spread out over multiple deposits.
• Slot bonuses no deposit: This type of online slot bonus can be harder to find, but they offer a risk-free way to trial a new casino. A no deposit bonus gives new players a limited amount of bonus cash in their casino accounts, without the need to deposit any cash of their own.
• Cashback bonuses: Most regular slots players will see losses as well as wins, and a cashback bonus is there to soften the blow when you’ve been unlucky. Over a given period of time, a casino with a cashback offer will return a portion of your losses to your casino cash account, no strings attached.
• Slots special offers: This covers a wide range of slot bonuses; for example, some casinos have a ‘slot of the day/week’ promotion offering free spins on the selected slot. Look out for seasonal slots offers too – for example, casinos may have a special offer on a Halloween-themed slot in October.
• Payment method bonuses: some operators will offer bonuses if you use a specific payment method – for example, you might be entitled to a PayPal slots bonus if you deposit with PayPal.

How we Select the Best Slot Bonuses

Practically every online casino has bonuses for players, but there are so many to choose from that choosing the right one can be a challenge. If it’s only slots that you’re interested in, then you want to find casinos with bonuses that are especially aimed at slot games, or even casinos that include only slots in their games selection.

Here at NewCasinoUK, we have collected together all the best new UK casinos in one place. Every one of our recommended online casinos is fully licensed for players in this country, so you can sign up and play with peace of mind. We have also singled out a selection of the best slots sites where you will find the best slot bonus UK for new and existing players. Browse our casino reviews to find your perfect fit.

We consider many criteria when weighing up the various value of a UK slots bonus. This includes the value of the bonus, as well as the conditions and limits that apply. As you may have already guessed, redeeming a juicy slots bonus is the best way to grant yourself a kick start when playing online slots with real money.

How to Redeem a Slot Bonus UK

Choosing among the best slots bonuses for UK players can be a hard task. Thankfully, NewCasinoUK has done all the work for you by selecting only top-value UK slots bonus offers from licensed slot sites. Make sure you follow these steps to redeem your slot bonus and start playing with your extra funds for extra fun!

1. Choose one of our licensed slot sites. Select your favourite operator from our exclusive toplist. We only feature UK operators that are licensed by the UK Gambling Commission. Safety and player protection are paramount for us!
2. Open a new account. In order to qualify for a slots bonus for new players, you need to successfully register an account. UK regulations are rather strict and you will be asked to provide your personal detail (including a copy of your ID) as well as proof of address.
3. Find the slots bonus. Navigate to the casino’s promotions page or check your email for any promotional offers. Look for the slots bonus that you wish to redeem, and read the terms and conditions to understand the eligibility criteria, wagering requirements, and any other rules associated with the bonus.
4. Enter a bonus code (if applicable). Some slots bonuses may require a bonus code to be activated. If this is the case, enter the code in the designated field during the registration process, deposit process, or in your account settings, depending on the casino’s instructions.
5. Make a deposit (if required). If the slots bonus is part of a deposit-based promotion, such as a welcome bonus or a reload bonus, you’ll need to make a qualifying deposit. Head to the casino’s cashier or banking page, select your preferred payment method, and follow the instructions to complete the deposit. Make sure to deposit the minimum amount required to be eligible for the bonus.
6. Claim your slots bonus. Once you’ve completed the necessary steps, the slots bonus should be credited to your account automatically. If it’s not, you may need to manually claim the bonus by contacting the casino’s customer support or following any other instructions provided by the casino.
7. Start playing. With the bonus funds or free spins credited to your account, navigate to the eligible slot games and start playing. Ensure you follow the terms and conditions associated with the slots bonus, including any game restrictions, wagering requirements, and time limits.

Best Slots Bonus T&C’s

As most slots players will know, even the very best slots bonus comes with some strings attached. The most significant condition placed on a slots bonus is the wagering requirement. Essentially, wagering or playthrough requirements mean that the money you won thanks to your slots bonus must be wagered a certain number of times before it can be transferred to your cash account and withdrawn. Understanding the T&C is crucial when redeeming a slots bonus, as they determine the eligibility criteria, wagering requirements, game restrictions, time limits, and other rules associated with the bonus. Here are some of the most common terms and conditions that you may encounter when using a slots bonus.

Eligibility Criteria

Slots bonuses may have specific eligibility criteria that must be met before the bonus can be claimed. For example, you may need to be a new player, deposit a minimum amount, or use a specific payment method to qualify. Make sure to read the T&C carefully to ensure you’re eligible for the bonus.

Wagering Requirements

Wagering requirements, also known as playthrough requirements, refer to the number of times the slots bonus funds or winnings from free spins must be wagered before they can be withdrawn. For example, if a bonus has a 20x wagering requirement and you receive £50 in bonus funds, you would need to wager £1,000 (20 x £50) before you can withdraw any winnings. Wagering requirements are always clearly stated in the terms and conditions, and appear as a multiple number such as x10, x20 or x30. Free slot bonuses no deposit often come with some of the highest wagering requirements. Be sure to check the wagering requirements before accepting a slots bonus, as high requirements can make it difficult to withdraw winnings.

Game Restrictions

Slots bonuses may be limited to specific games or game categories. For example, free spins may only be available on a particular slot game or a set of slot games. Make sure to read the T&C to determine which games are eligible for the bonus.

Time Limits

Slots bonuses typically have time limits attached to them, meaning you need to use the bonus within a specific time frame. This can range from a few days to several weeks, depending on the promotion. If you don’t use the bonus within the time limit, it may expire and become void.

Maximum Bet Limits

Some slots bonuses may have maximum bet limits attached to them, meaning you cannot bet more than a specified amount per spin. This is usually done to prevent players from betting large sums of money and reducing the risk for the casino.

Maximum Cashout Limits

Slots bonuses may also have maximum cashout limits, which limit the amount you can withdraw from the bonus funds or winnings from free spins. For example, if a bonus has a maximum cashout limit of £500 and you win £1,000, you would only be able to withdraw £500. The maximum cashout limits are clearly stated in the T&C section of each and every slots bonus UK.

How to Clear a Slots Bonus Requirements

The best way to clear the requirements for all our recommended UK slot bonus offers is to play high RTP slots with maximum wagering contributions. Even if you are offered a bonus that can be used on other types of games, like blackjack, poker or bingo, playing your bonus on slots only is still the best option. This is for a couple of reasons. First, slots generally count towards 100% of the wagering requirements, while other games may only contribute a small percentage. The second reason is that online slots tend to have a very high return to player (RTP) rate, often more than 95%, and so you have a better chance of fulfilling the requirements before the money runs out – especially if you’re lucky enough to make a big win during the bonus play.

Best Slots Bonuses – No Wagering

These days we’re seeing more and more bonuses for slots with no wagering strings attached. They are more common with free spins offers than with deposit match bonuses. Within our selection of casinos offering the best online slot bonuses, you will find some that are completely wager-free. This means that if you win, the money goes straight to your cash account and can be withdrawn if you wish.

Sounds too good to be true? Then you can take a look at our guide to no wagering casino sites – find out where you can play without wagering requirements and enjoy your bonus and winnings without any strings attached!

In-Game Slot Bonus Features

Modern online slots are known for their exciting bonus features, which add an extra layer of entertainment and winning potential to the gameplay. From expanding wheels to cascading reels to free spins, here are some of the most common and popular bonus features in online slots.

Free Spins

Free spins are a classic bonus feature that offers players a certain number of spins on the slot machine without having to place a bet. These spins are usually triggered by landing a specific combination of symbols on the reels. Free spins can also come with multipliers, expanding wilds, and other features that can increase your chances of winning.

Expanding/Sticky Wilds

Wilds are symbols that can substitute for other symbols to create winning combinations. Expanding wilds can expand to cover the entire reel, increasing your chances of landing a winning combination. Sticky wilds can stay on the reels for several spins, providing more opportunities for wins.

Scatters

Scatter symbols can trigger bonus rounds or free spins when landed on the reels. They typically do not need to be on a payline to trigger the bonus feature, and landing multiple scatter symbols can increase the number of free spins or the multiplier value.

Bonus Rounds

Bonus rounds are special features that offer players the chance to win additional prizes or free spins. They can be triggered by landing a specific combination of symbols or by activating a specific feature during gameplay. Bonus rounds can range from simple pick-and-win games to more complex mini-games that involve skill-based challenges.

Cascading Reels

Cascading reels, also known as tumbling reels or avalanche reels, are a feature where symbols that form a winning combination are replaced by new symbols falling from above. This can create a chain reaction of wins, with new symbols falling into place and potentially triggering additional wins.

Multipliers

Multipliers are a feature that can increase the value of your winnings. They can be triggered by landing a specific combination of symbols or during a free spins bonus round. Multipliers can range from 2x to 10x or higher, increasing your potential winnings significantly.

How Volatility Affects the Value of Slots Bonuses

Volatility, also known as variance, plays a crucial role in determining the value of a slot bonus. In the context of slot games, volatility refers to the level of risk associated with a particular game and the frequency and size of payouts. There are generally three levels of volatility: low, medium, and high. Understanding how volatility affects the value of a slot bonus can help you make informed decisions when choosing which games to play with your bonus funds or free spins.

• Low Volatility. Low volatility slots offer frequent, smaller payouts. When playing with a slot bonus on a low volatility game, you can expect more consistent wins, which can help you meet wagering requirements or extend your gameplay. However, the downside is that the payouts are generally smaller, limiting the potential for massive wins.
• Medium Volatility. Medium volatility slots strike a balance between the frequency and size of payouts. When using a slot bonus on a medium volatility game, you have a moderate chance of meeting wagering requirements and a fair chance of landing a sizable win. Medium volatility slots are an excellent option for players who want a combination of regular wins and the potential for bigger payouts.
• High Volatility. High volatility slots are characterized by infrequent, large payouts. Using a slot bonus on a high volatility game can be a double-edged sword. On one hand, the potential for massive wins is appealing, especially when using bonus funds or free spins. On the other hand, the high risk can make it challenging to meet wagering requirements or maintain your bankroll.

When choosing a slot game to play with your bonus, it’s essential to consider your risk tolerance, the wagering requirements associated with the bonus, and your overall gaming preferences. Low volatility slots are better suited for meeting wagering requirements, while high volatility slots offer the potential for significant wins. Medium volatility slots provide a balanced experience, making them a popular choice among players. By understanding the impact of volatility on the value of a slot bonus, you can select the most suitable games and maximize your winning potential.

Most Popular Slots with Bonuses

As previously explained, the majority of slots bonuses offered by UK casinos and slot sites are only available on select slots. Some of the most popular slots that you can find dedicated slotys bonuses for include major hits such as NetEnt’s Starburst. Let’s take a closer look.

Starburst

Starburst is a massively popular online slot game developed by NetEnt in 2012. Starburst features a 5-reel, 3-row layout with 10 paylines, offering players various ways to win. The paylines function both ways, from left to right and right to left, increasing the winning potential. The Starburst Wild symbol is the game’s standout feature. When it appears on reels 2, 3, or 4, it expands to cover the entire reel, triggering a re-spin with the Wild reel held in place. Players can win up to 3 re-spins if new Starburst Wilds appear during the feature, offering the chance for substantial wins.

The game features a 5-reel, 3-row layout with 10 adjustable paylines. The Book of Dead symbol serves as both the Wild and Scatter symbol in the game, substituting for other symbols to create winning combinations and triggering the Free Spins feature. When three or more Book of Dead symbols land on the reels, players are awarded 10 free spins.

Big Bass Bonanza is a medium-to-high volatility slot, appealing to players who enjoy the thrill of chasing larger wins. The game’s fun theme, combined with its Free Spins feature and potential for big payouts, has made Big Bass Bonanza a popular choice among online slot enthusiasts.
