GUIDE TO UK CASINO SLOTS BONUSES IN 2021

One of the most common ways to increase your starting funds is by hunting around for the best casino slots bonuses. These bonuses will give you more funds to play with – meaning more spins at the slot machines than if you would have played without a bonus.

At SlotsHawk, we give you access to casinos offering every slot bonus available. We exist to help you get the most out of online casinos. SlotsHawk is the only guide in the UK that reports live on the slots bonuses of all casinos.

So, where can you find exclusive slots bonuses? How much of the bonus can you withdraw? What purpose do bonuses serve? You will discover slots bonuses at almost all UK slot sites and casinos. Bonuses are used to entice potential customers to sign up.

We are sorry to tell you that withdrawing a bonus is no easy task. First of all, there is often a minimum deposit requirement for you to receive your bonus.  Secondly, when you do have access to your bonus, there will usually be wagering limitations and guidelines attached to the bonus.

The purpose of a UK slots bonus is for betting sites to tempt players into signing up.The competition between online casinos has never been higher and a casino will draw in a player by incentivising them with a shiny bonus.

With this being said, online casino bonuses are really popular for bonus hunters who go from casino to casino looking to take advantage of the casino’s money Bonuses can also be useful if the rules stipulating them are relaxed.

At SlotsHawk you can find:

  • No Wager free spins
  • Bonus codes
  • Slot site guides
  • Slot reviews
  • New slot sites every month

WAGERING REQUIREMENTS

If you want to make the most of a slots bonus then you should arm yourself with the knowledge surrounding wagering requirements. Wagering requirements are the single most important aspect when it comes to casino bonuses.

If a wagering requirement is attached to your online casino bonus, you will need to do something in order to either activate the bonus or withdraw any cash made from using the bonus.

It is very important to keep track on how much you must wager on a bonus when playing slots. Frequently, you will have to wager your bonus a specific amount of times before you are allowed to withdraw any winnings you receive from using your bonus money or free spins.

Wagering Requirement Example: If you sign up to an online casino offering a 100% deposit match bonus with a 30x wagering requirement, you must bet £3,000 on the slot machines before any winnings from the bonus can be withdrawn. Wagering requirements vary from casino to casino. You will find a casino’s wagering requirements in their terms and conditions.

The SlotsHawk recommends picking a casino with a low wagering requirement for their slots bonus. See the list below for the casinos with the lowest wagering requirements on their bonuses.

  •  All British Casino
  •  Fun Casino
  •  Yako Casino
  •  Casino Casino

TYPES OF SLOTS BONUSES

best slots bonuses

We will now take you through the variations of slots bonuses that are available to both new and existing casino players.

WELCOME BONUSES AND SIGN UP OFFERS

New players will receive some sort of welcome bonus. Welcome bonuses usually come in the forms of matched deposit bonuses.

This is where you make a deposit of a specific amount and the casino replicates the amount and adds it to your balance.

Welcome bonuses can also come in the form of free spins. If you scroll up to the top of this page you will find all the best welcome bonuses and sign up offers that are given exclusively to UK players.

FREE SPINS AND BONUS SPINS

Free spins bonuses give you the opportunity to play online slot games for free.

Free spins, also known as bonus spins or extra spins, are usually awarded to players as a welcome bonus after a deposit is made or as a loyalty bonus to players who regularly play casino slot games. Any money made from using bonus spins almost always come with wagering requirements. If you are lucky, you can sometimes come across no deposit free spins.

We have listed a bunch of them in our no deposit free spins list.

You can also get bonus spins for as little as a £5 deposit.

DEPOSIT BONUSES

An extremely common slots bonus for new depositing players, deposit bonuses are additional payments made by a casino into a players account after the player has made a cash deposit.

Deposit bonuses come in the form of match bonuses and bonus spins that players can use on most slot machines.

At SlotsHawk we love a good deposit bonus. That’s the reason we have compiled several lists of them that you can find below. Click on the link and you will get redirected to the correct page.

BEST TYPES OF DEPOSIT BONUSES

Important to keep in mind! The highest bonus is not necessarily the best bonus. As a rule of thumb – the bigger the deposit bonus, the higher you can expect the wagering requirements to be.

NO DEPOSIT BONUSES

A no deposit bonus is always popular. These bonuses usually come in the form of cash amounts or wager free spins.

No deposit bonuses are added to a players account as soon as they are registered at the casino offering the bonus.

Wagering limitations and other specifications will generally feature a no deposit bonus but are traditionally less restrictive compared with deposit bonuses.

FREE SPINS NO WAGERING

The most popular types of bonuses but also some of the rarest, no wager free spins allow players to use free spins without having to adhere to any wagering requirements.

MOst free spins bonuses come with strict wagering requirements. But there are online casinos which offer free spins no wagering.

Check out our guide to Free Spins No Wagering for more information.

WEEKLY AND MONTHLY BONUSES

Weekly and monthly bonuses are awarded by casinos to their existing players. These bonuses are exactly how they sound.

Some casinos reward players for being active and offer bonuses based on the players own weekly or monthly deposits.

Wagering requirements and restrictions are likely to be applied to these bonuses so we remind you to read the respective casinos terms and conditions regarding weekly and monthly bonuses.

VIP AND HIGH ROLLER BONUSES

Some online casinos will give bonuses to players who are willing to make exceptionally large cash deposits into their casino account.

The casinos which can afford to accommodate these types of players will offer a bonus based on the percentage of the deposit. These bonuses usually range between 40-50%. 

Looking for the best high-roller casino? SlotsHawk can recommend:

CASHBACK SLOT BONUSES

Depending on the casino, you can get cashback on your losses between 10%-25% when playing slots. Most online casinos will also offer you a deposit bonus on top of the regular cashback.

At almost all sites, you will receive the cashback at the end of the week. So if you had a rough loosing streek, you can always expect to get something back once a new week begins.

Here you can find all casinos offering cashback on slots.

RAFFLES AND EXISTING PLAYER BONUSES

Casinos will do everything in their power to persuade new players to register and make a deposit, but they will also ensure their current players are kept happy by offering existing player bonuses and raffles.

Raffles often come in the form of leaderboards whereby players must play certain slot games in order to climb up the leaderboard. Bonuses including cash prizes are awarded depending on leaderboard position.

Looking for a casino that offers players raffles and existing player bonuses? SlotsHawk can recommend:

SLOTS BONUS CODES

As a slot site guide, SlotsHawk likes to make things easy for you. We have a full page on slots bonus codes for you to make use of. Bonus codes offer free spins completely without wagering requirements.

CHOOSING THE BEST SLOTS BONUS

Now that you know all the types of slots bonuses, it is time to decide the best one for you.

Our recommendation is that you should not rely on the size of the bonus when picking from our list of UK slot sites. Choose a casino you like the look of and which gives you access to your favourite casino and slot games.
