Types of Slots Bonuses
There are a few different kinds of online slots bonuses out there, and we will go into more detail about some of them further down this page. When you are picking a slot bonus, here are some of the types you will find.
Welcome bonus
When new players sign up with a casino site they are almost always eligible for a welcome bonus. This is not exclusively to be used on slot games, but due to the terms and conditions it usually works out better to avoid other games when using the bonus. We go into more detail in the section on terms and conditions later on, but the short version is this; you will get the best value from a welcome offer if you use it as a slots bonus.
Deposit bonus
A deposit bonus is an offer that gives you something extra when you make a deposit into your casino cash account. This could be a first deposit casino bonus, or a reload bonus for existing players. The same applies as with the welcome bonus – use it as a slots bonus to get the maximum value.
Free spins
Free spins really are online slots bonuses – the ‘spins’ refers to the spinning reels of the slot games, as opposed to a roulette wheel. Casinos give players free spins offers under a variety of circumstances. For example, as part of a welcome offer or reload bonus, as a way to promote a game, or as a reward for VIP players. Free spins are often restricted to just one game, or a small selection. There are also free spins no deposit slots bonuses, and free spins with no wagering. Keep reading to learn more.
How to find the Best Slots Bonus
The best slot bonuses are the ones that give the maximum value to the player. Some of the things that make a great slot bonus are as follows:
- Low or no wagering
- Relatively high spin value
- High number of free spins
- High cap on winnings
- High match percentage on a deposit bonus
- Can be used on the best quality games
Of course, not every online slots bonus can fulfil all these criteria, but a good one will hit at least two or more of what we listed. If you want to know everything about a slots bonus then you will need to carefully read through all the terms and conditions, but that takes a lot of time.
That’s where we come in. We have examined hundreds of online casino slots bonuses. The best casino sites listed has what we consider to be a good slots bonus, so all you have to do is decide which one is your favorite.
How we examine Online Slots Bonuses
Before we can look at the online slot bonus, we must first give the casino itself the green light. Here is our checklist for what makes a good casino:
- Licensed in a recognised jurisdiction
- Employs top-level online security
- Excellent selection of games from a range of software providers
- Commitment to responsible gaming
- Fast and convenient banking
- Strong customer service
- User-friendly interface on a range of devices
We also take into account factors related to the appearance of the site, such as the theme and the layout of the gaming lobby.
When it comes to examining the slot bonuses, we ask two fundamental questions:
- Are the terms and conditions fair?
- Does the slots bonus add real value for the player?
If the bonus satisfies those two questions, then it has our seal of approval and we include it in our listings.
Online Slots Bonus No Deposit
Some players regard the no deposit slots bonus as the holy grail of casino offers. We have to agree that there is a lot to love about the no deposit slot bonus, but there are also some downsides that we should highlight. But first, what exactly is a no deposit bonus?
As the name suggests, this is an offer that gives players an option to play slots without putting any money into their casino account. It’s a popular bonus, although rare, because it presents absolutely zero risk to the player. A no deposit slots bonus can either be in the form of casino credit, or free spins. All you need to do is make an account at the casino, and you can get the bonus. Use it on the eligible slot game or games, and then decide if you want to carry on using that casino or move on.
There are a few limitations to a slots bonus no deposit offer, however. The first thing to know is that you are unlikely to win much cash from this type of offer. It is a great way to play some games for free, but the casino includes some conditions to minimise cash winnings.
When the no deposit slot bonus is a casino credit offer, the value will be quite small – typically in the region of $5 to $15. Similarly, free spins offers provide a low number of spins, usually with a low spin value too. There is almost always a cap on the amount of cash you can win, even if all wagering requirements are satisfied. Finally, if you do end up in credit, the casino may not release your winnings until you have made a cash deposit.
Slots Bonus No Wagering Requirements
A slot bonus with no wagering requirements is one of the better deals that you can find at an online casino. This bonus structure is most often found with a free spins offer. They are sometimes advertised as wager-free spins, or no wagering free spins, and they are usually available as part of a deposit bonus or welcome offer.
The great thing about a slot bonus no wagering is that any winnings from the free spins are yours to keep. These offers are becoming more common, and they present real value to the player. While you cannot control the value of each spin, and often you cannot choose the slot game on which the bonus is used, even so it gives players the best chance of winning some real cash.
The wagering requirements are the biggest limiting factor to most online slot bonus offers, so in our eyes there is very little downside to this type of bonus. You probably won’t win big, but if you make a bit of profit then you can go on to use that cash however you like. And if you then go and use your winnings on a low house edge game like video poker, you may well be able to make a tidy profit.
Terms & Conditions for a Slot Bonus
Nothing in this world comes absolutely free, and this is true for online casino slots bonuses as well. The casino operators put limitations on bonuses for a few different reasons. First and foremost, casinos don’t want to be handing out free money because that would affect their bottom line too much. Second, these limitations prevent bonus hunting, which is when players use a bonus to win money but then move on to another site. Finally, some of the conditions are there to fulfil the casino’s obligation to anti-money laundering and responsible gambling.
Luckily, all the casinos that we recommend are also committed to transparency, so all these limitations are plainly stated in the slots bonus terms and conditions. Most sites list these conditions separately to the main T&Cs section. Let’s take a look at some of these terms that are common to most slot bonuses:
Wagering requirements
As we saw earlier, wagering – also known as playthrough – is the biggest limiting factor to any bonus. It is there to ensure that players have a lower chance of getting any cash winnings from a bonus offer. Wagering can be as low as 1x or as high as 50x, sometimes even higher. The wagering number refers to how many times the bonus (or winnings from free spins) must be wagered before the money is converted to cash and can be withdrawn.
As an example, let’s take free spins with wagering of 30x. Having used all the free spins, you have won $5 overall. You must then make wagers to the value of $5 x 30 = $150 before the winnings are added to your cash account. As you can see, it then becomes harder to convert your casino bonus into cash winnings.
Time limits
Most online slots bonuses are only valid for a short period of time after activation. This is usually a week or two, after which any unplayed bonus funds are void. All wagering must be completed within the time period as well.
Game restrictions
If you get a slot bonus, especially a free spins offer, then you can usually only use it on a select number of slot games chosen by the casino. Game restrictions also apply to the wagering requirements, if there are any. In this case, wagering should be completed on slot games only. This is because most other games contribute only a small percentage towards wagering.
Spin value and win caps
With a free spins bonus, the casino usually sets the value of each spin quite low, so that any resultant wins are also not that high. And even if you get very lucky, there is usually a maximum amount that you can win – look out for this condition especially with slots bonus no deposit or no wagering offers.
The above listed are the most frequent terms and conditions for slots bonus offers, but each site applies them a little differently. Most will have some additional T&Cs as well. If you are ever uncertain about a condition, then you can contact the customer support for a more detailed explanation.
