How to Choose the Best Slot Bonus

When choosing looking for the best slot bonus to play with, there are a number of thing you should look out.

  • No Deposit Bonus
  • First Deposit Bonus
  • Wagering Requirements

A term you’ll come across with virtually all casino welcome bonuses is ‘wagering requirement’. This is something you definitely need to understand if you want to be able to withdraw your bonuses, and it will help you to make the best choose in terms of which offer you want to choose.

A ‘wagering requirement’ is simply how many times you have to bet the bonus amount you have been given before you can withdraw it.

For example, if a sign up offer on a particular casino is ‘100% First Deposit Bonus up to £100’, if you deposit £100 you get an additional £100 in bonuses. Although you will most likely be able to play with this bonus immediately, in most cases you won’t be able to withdraw it before you meet the ‘wagering requirements’.

Wagering requirements typically range from 4x-50x the actual amount of the bonus. If the wagering requirement was 10x, then you would have to wager £1000 in order to be able to withdraw your bonus money. Now, it is possible that could do this just repeatedly using your bonus money, but there is a good chance you will have to use the money you actually deposited and possibly money from further deposits. This is certainly likely to be the case when wagering requirements are higher.

Therefore, you shouldn’t simply be attracted to the biggest looking bonus, because if it has a 40x wagering requirement to claim, there is a good chance you might not want to wager that much.

What Types of Slot Bonuses Are There?

Free Spins

One of the most common types of bonuses are free spins – I mean who doesn’t love free spins, right? There’s just something appealing about being able to get something for nothing, especially when there are big prizes on the line. Some casinos might cap the winnings you can make from free spins, but others, such as 888, even allow you to win the jackpot with them.

However, free spins are not always as simple as they seem on the surface. The best type are ones that you get without having to make a deposit and you don’t have to wager them. You also get ones that you immediately get for free, but do have wagering requirements in order to be able to withdraw your winnings. Sometimes you will be granted them after making a deposit. Sometimes you will be given them after fulfilling your wager requirements for your deposit bonus. 

The value of the free spins typically range from £0.01-£0.20, with £0.10 being the average. 

You might see two different promotions where on one hand, 200 free spins are being offered, whilst 30 free spins are being offered at another slots sites. Although the 200 free spins might seem like a much more attractive offer on the surface, it’s just as important to look at the value of the spins when determining which one to go for. 

No Deposit Bonuses

Some of the best slot bonuses are ones which require absolutely no deposit, meaning that you don’t even have to make a payment to start playing with real money.

Oftentimes, no deposit bonuses will come in the form of free spins, which may or may not have wagering requirements.

Everyone loves free spins. However, a lot of free spins bonuses are deceptive in that you can’t actually withdraw your winnings until you have wagered them a ridiculous number of times. This is why casino sites with no wagering requirements are particularly good, as there is no nonsense in terms of being able to withdraw your money. 

First Deposit Bonus 

The biggest bonuses virtually always come in the form of first deposit bonuses, otherwise known as ‘welcome offers’, and can come in a variety of forms.

A common offer is to get a 100% match of your first deposit in additional bonus funds. Usually you’re able to play with these bonus funds straight away, however there are nearly always wagering requirements in order to be able to be able to withdraw them.

This means that you have to play with the ‘bonus’ amount you have been credited multiple times over before you’re allowed to withdraw it, by which time you may or may not still have it. 

Wagering requirements for first deposit bonuses typically vary from 10x-50x, depending on the size of the offer. The most lucrative offers tend to have the biggest wagering requirements and therefore only big players really have a chance of being able to redeem the full bonus. 

It’s a good idea to work out how much you would have to wager in order to be able to withdraw your bonus money before making a deposit. 

If you make a bigger first deposit, then although you might be given a bigger bonus, you will have to wager far more money in order to be able to unlock the bonus, so make sure to keep that in consideration.

Check out our list of the best first deposit bonuses to see our top picks!

Cashback

A much more unusual type of bonus is ‘cashback’. Typically slots sites that offer this don’t provide big welcome bonuses, or even welcome bonuses at all, but this comes with the pro that there usually aren’t any wagering requirements.

The way it usually works is that the casino gives you a percentage of your losses back to you if you lose your money. A great example of this is the All British Casino. 

An exception to this is the slots site PlayOjo, which gives players roughly 0.6% cashback on every single spin, regardless of whether they win or lose. This essentially boosts the RTP of all of their slots and is a fantastic feature.

Tournaments

Slot tournaments are an excellent way to earn bonuses even after you have completed the sign up bonus.

Since slots are ultimately luck based, the idea of having slot tournaments might seem slightly strange. However, certain brands, such as Mr Green, have put their own unique twist on them and it gives players an extra element of fun and incentive to play.

At Mr Green, the tournaments occur every 15 minutes are known as Reel Thrills, whereby players can earn free spins by achieving the highest percentage win on their spins.

We expect to see more casinos offering tournament style bonuses in the future, as we think they are a great way to keep players engaged and to reward them for being loyal players.

What Payment Methods Can You Use to Play Slots?

A whole variety of different payment methods can be used to play slots online, however the ones you can use vary from site to site.

For example, not all casinos accept Paypal as a deposit method, so it’s worth checking our list if Paypal is your chosen payment method.

Other payment methods include Skrill, Paysafecard, Neteller and many more. However, in general, using a debit card is the most common option and is accepted by virtually every slots site online. 

How to Withdraw Your Money From Online Casinos

If you’re lucky enough to come out in the green after a session of playing slots, then it’s important to know how you can actually withdraw your winnings. 

There are generally fewer payment options for being able to make withdrawals in comparison to deposits, and there are sometimes even fees and long waiting periods. 

Therefore, it’s important to pick a slots site where you can use your preferred withdrawal method and one where you can avoid withdrawal fees and long processing fees if it at all possible. 

How to Win Playing Slots? Understanding RTP 

It’s no secret that slots are slightly tilted in the house’s favour – after all, that’s how casinos make their money. However, this is not to say that all slots are the same – in fact, the actual RTP (Return to Player) can vary massively across different slot games, so it’s a good idea to only play the games which are going to give you the best chance of winning.

RTP is a term used to determine how much of the money put into a slot is actually returned to the players and it is measured as a percentage. A normal RTP for slot games ranges from 93-96%, but some games provide an RTP as high as 98%.

This might seem like a deceptively small difference in terms of the percentage, but you shouldn’t underestimate how much better your odds of winning are if you play on the slots which give the highest payout and return to the players.

It is worth noting that sometimes the slots with the highest RTP are excluded from contributing towards wagering requirements, such as Blood Suckers, so it is always worth reading the specific terms and conditions for the slots site you are going to sign up with. 

The Best ‘No Wagering’ Slots Bonus

If you’re fed up with complicated wagering requirements and want a solid bonus to get you started with slots on a new casino, we’ve compiled a list of the best online casinos that have absolutely no wagering requirements – at all!

While wagering requirements can sometimes be justified if there are massive bonuses to go with them, a lot of the time they’re just dishonest, misleading and extremely difficult to actually complete.

Casinos that have no wagering requirements for their bonuses are nearly always the most honest and transparent, so we’ve gone ahead and compiled a list of the very best no wagering slots sites!

The bonuses usually come in the form of free spins and you’re free to withdraw winnings from them immediately!

PlayOjo offers 30 spins with absolutely no wagering requirements once you deposit £10, and is the best no wagering slots bonus currently on offer.

50 Free Spins

Best Slots Sites For Mobile – Which Casino Has The Best App?

We find it astonishing that so many casinos still don’t have decent apps for mobile players!

What’s more, a lot of them don’t offer mobile players the same bonuses as PC players, which is just absurd.

If you’re looking to play slots on mobile, here are the top things you’re looking for:

  • A highly functional app with a great playing experience
  • Easy deposit and withdrawal options
  • A great sign up bonus

Unfortunately, few casinos can fulfil these three criteria and many players find themselves on shoddy sites or apps that lag and consistently crash.
