WHAT ARE CASINO WELCOME BONUES?
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.com, 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.
ARE WAGERING REQUIREMENTS INCLUDED?
Yes, wagering requirements are often a part of any casino welcome bonus. However, there is a small collection of online casinos which offer bonuses without 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with a 30x wagering requirement, you must bet £3,000 on the slot machines before any winnings from the bonus can be withdrawn.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.
SlotsHawk recommends picking a casino with a low wagering requirement for their slots bonus. See the list below for the casinos with no wagering requirements on their bonuses.
- Bally Casino
- Betfred
- Virgin Games
WHAT ARE THE DIFFERENT TYPES OF 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 guide.
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
- 200% Slots Deposit Bonus
- 300% Slots Deposit Bonus
- 400% Slots Deposit Bonus
- Deposit £10 Play with £30 Slots
- Deposit £10 Play with £40 Slots
- Deposit £10 Play with £50 Slots
- Deposit £10 Play with £60 Slots
- Deposit £10 Play with £70 Slots
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.
FREE SPIN 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.
Find all free spins on deposit bonuses below:
RELOAD BONUSES
Casinos with Reload bonus offers are designed to give incentives to new players to keep playing. Most reload bonuses are triggered upon second and third deposits. These are usually in the form of 50% matched deposits.
Not all online casino’s have reload bonuses, although the majority will.
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.
