Types of Slot Bonuses

There are various kinds of slot bonuses available. There are several types of slot offers available for new players upon joining a casino. The really good casinos also look after their loyal customers and offer them the best slot bonus, UK offers and so on, only to make sure that there is always something their players can benefit from. Here are the slots bonuses that you will find at online casinos.

First Deposit Bonus – This is the most common type of bonus you can find. With so much choice of online casinos, operators offer these welcome bonuses as an incentive to choose their casino. The amounts vary from one casino to the next, and sometimes apply to your first deposit only, whereas some offer a package deal where your subsequent deposits will also be rewarded with a bonus. 888casino offer players a 100% bonus on their first deposit, up to a maximum of £100. Betfair Casino will give you up to £50 welcome bonus on your first deposit. Mr Green offer a welcome bonus that comes in 2 parts. Not only can you get £100 on your first deposit, but you can enjoy an amazing package of 88 free spins as a no deposit bonus at 888casino.

No-Deposit Slot Bonus, UK – Some operators will give you a free bonus to encourage you to play at their casino. These can be a great way to test out the casino and its games without parting with any of your own money. You’ll find some operators offer their free slots bonus for all games, whereas some give you access to a selected set of games. This gives you a great chance to either try your luck on 1 particular slot, or have a spin on a few, to see which you like best. 888casino give their new customers a whopping set of 88 spins for free at your registration. They are valid on selected games only and have only 1x wagering requirement.

Free Spins – Another type of free welcome bonus you will find for slots is free spins. As the name suggests, you are given a set number of spins to play certain slots, and you do not need to make a deposit to benefit from the offer. Simply register and your free spins will be waiting for you to play with. Any winnings you make with the free spins will be added to your bonus account, giving you more chances to play and win. Many of the best online casino bonuses in the UK include free spins.

After you’ve benefited from your welcome bonus, there are various ongoing promotions that give you more bonuses to play your favourite games. These vary from one operator to another and include the following:

Bonus spins – These are free spins that are given for making a deposit. The more you deposit, the more bonus spins you are awarded. Any winnings you make with your bonus spins become a bonus that you can play with, giving you lots of extra play and more chances to hit the big jackpots. You’ll find this type of bonus available every Tuesday at Mr Green. Free spins can be part of any other bonus, as well. Many casinos add them to the first-deposit offer or other promotions.

Free Play – This is where casinos will give you a free play bonus when you make a deposit. This gives you extra bonus funds to play a selection of games. You will find this type of offer at 888casino, as part of their daily deals promotion. For example, when you make a deposit on a Monday, you’ll get up to £150 free play to use on a choice of 5 of their progressive jackpot games. Of course, when you get a free play bonus, you have more opportunities to play and win the big prizes.

Cash Drops – This is a promotion that gives you the opportunity to win even more money by playing a specified game. You will find cash drop promotions running regularly at Mr Green. When you play a specified slot on the day of the offer, you can win extra prizes of between £5 and £250. Mr Green randomly selects players who have participated in the cash drop game and credits their accounts with the extra money. The great thing about Mr Green’s cash drop promotion is that when you win these bonus prizes, they are credited to your account as real cash, they have no wagering requirements attached. So it’s your choice whether to withdraw your winnings, or use them to play more games and try to win even bigger prizes.

Slot Tournaments – This is a type of competition that runs on a particular selection of slots, with prizes available for the winners. Mr Green have slot tournaments every weekend. You simply play any of the slots that are included in the tournament, and the 5 players with the highest percentage win over 20 consecutive spins throughout the competition will be rewarded with monetary prizes. As with cash drop prizes, you will be credited with real moeny.

Bonus Wagering Requirements

Casinos offer some of the best slot bonus and UK offers in order give you more opportunity to play. Therefore, any bonus you accept will come with wagering conditions. You will need to play through your bonus amount a certain number of times before you can withdraw any winnings you have made with it. Different casino games contribute different amounts towards playthrough requirements. The great news with slots is that any money you wager will count 100% towards your wagering requirements. When you compare this to say roulette, which can contribute as little as 5%, or may not even contribute at all at some casinos, then achieving the wagering requirements for a slots bonus is very simple and easy to do.

When you are choosing a bonus, you should ensure you understand the playthrough requirements attached to it. They can vary greatly from one operator to the next. We have seen casinos with wagering requirements of 120x, this is huge compared to our top 3 casinos. Take 888casino for example, you will need to wager your bonus amount 30 times in order to withdraw winnings made with it. So if you were to deposit £100 and get the maximum bonus of £100, you would need to wager 30 x 100 = £3000. Not to mention that the no deposit 88 free spins at the casino have only 1x wagering requirement. Far more favourable than the £12000 you’d have to wager with a 120 x requirement!

You should also check how long the bonus is valid for. For example, at Betfair Casino, your first deposit bonus is valid for 7 days. This will suit the players who intend to play a lot of slots over short period of time. For those players who would like a longer time frame, then it would be better to opt for 888casino which gives you 14 days to clear the free spins bonus and a massive 90 days for the first deposit bonus.

We’ve put together the bonus conditions for the best online slots offers, to help you decide which best suits your needs and playing style. When it comes to bonuses, it is incredibly important to not get too enticed by large numbers and shiny banners. You should always check carefully about the specific terms and conditions the casino provides. If the bonus amount is big and attractive, you might get attracted by it and rush to deposit money. However, if the wagering requirements are incredibly high and the validity of the offer is so short that it would be impossible to fulfill the conditions, then the offer is not as great as it appears. In the table down below, we have carefully displayed the most important terms and conditions of the bonuses, which our top 7 operators provide.

As you can see, there are plenty of differences beyond the lump sum of the bonus. That is why we don’t always recommend the largest bonus – for new casino players, we would quite often advise them to pick the best slot bonus in the UK with longer validity and lower playthrough.

The Best Progressive Jackpots for Real Money Slot Wins!

One of the biggest draws of playing slots at an online casino is the huge amounts of money that can be won on progressive jackpot slots. There are some considerable amounts up for grabs. The largest amount of money ever won on an online slot was a staggering €17.8 million. The lucky winner scooped the jackpot on 20.01.2013, playing Mega Fortune. It is a 5-reel, 25-line slot, with a luxury theme. When 3 bonus wheel symbols appear, the jackpot bonus game is activated. The player then spins the wheel of fortune to win one of 3 jackpots – including the Mega Jackpot! If you fancy trying your luck on NetEnt’s most rewarding game, you can play Mega Fortune with your slots bonus at Mr Green.

Some of our favourite progressive games are Playtech’s Age of the Gods jackpots. There’s a huge assortment of slots featuring iconic Gods from Greek mythology. These include Zeus, Athena, Poseidon and Hercules, amongst others. Each of the Greek God themed games are linked to the Age of the Gods multi-level mystery progressive jackpots. There are 4 jackpots to win, Power, Extra Power, Super Power and the most lucrative Ultimate Power. When you play any of the slots in the series, the jackpot games are triggered randomly, however, the higher the bet the bigger the chances of entering the jackpot game. You do not have to get a certain pattern on the pay line, in fact, even a no win spin can trigger the jackpot game. Once the jackpot game is started, you are guaranteed to take home one of the 4 jackpots. You’ll see a grid of 20 squares which hide different jackpot symbols. You click on the squares to reveal the various jackpot symbols. Once you reveal 3 matching symbols, that is the jackpot prize you win. You can play the Age of the Gods jackpot games with the best slot bonus in the UK, right there, at Betfair.

The great thing about finding a good bonus is that it will give you extra chances to play and win these big progressive jackpot prizes. You will find that some operators give favourable bonus conditions for jackpot wins also. Take for example 888 Casino, you will need to wager any winnings you make from your free play bonus 30 times in order to make a withdrawal. However, progressive jackpots are the exception to the rule. If you strike it lucky and scoop the jackpot on Millionaire Genie, then the prize money is yours to keep. No playthrough required and no limit on your prize money. Only the 88 no deposit free spins have a wagering requirement of 1x.

In the following table, you can find helpful information about the bonus rounds, bet limits and RTPs of some of the most popular jackpot slots.

Of course, while choosing a slot is important, you should also keep the bigger picture in mind. If you want to play with real money and have an actual shot at the alluring jackpot, you should look to register at a casino where you will get good terms. You should also take a look at the platform, as you will probably want to play more than one game. With that in mind, here is our top progressive jackpot casino choice:
