What kinds of online slots bonuses are available?

Welcome bonuses

The welcome bonus is the first kind of bonus that a player will receive when they join an online slots site. These bonuses can be applied in a number of ways. No matter what kind of welcome bonus is applied, there is plenty of value for the player. The most popular kinds of welcome bonuses are deposit bonuses and free spins.

When it comes to deposit bonuses, they are generally applied as a percentage of the initial deposit. Those bonuses give players the chance to increase their bankroll before completing a single spin. These types of welcome bonuses vary based on the percentage of deposit that is bonused as well as the maximum initial deposit.

Obviously, the higher the percentage of the bonus, the larger the bonus potential. But the maximum deposit amount subject to the bonus is crucial. A welcome bonus of 100% with a £50 limit would be less impactful than a 50% bonus good for up to £200. Then again, what kind of bonuses are more impactful for you depends on your individual needs.

Meanwhile, free spins can be awarded to new players after they make a deposit or without a deposit depending on the rules set by an online slots bonus. A no deposit free spins bonus can be the best slots bonus. This is because a player has a chance to win big without having to spend anything to do so.

Reload bonuses

Just like welcome bonuses, reload bonuses give players a percentage of deposits made after their first. They typically are not as valuable as welcome bonuses, but do offer players the ability to increase their bankrolls. For players who like to play slots frequently, these bonuses are a great incentive to do so. They are also a great added value for something you had already planned on doing.

Loyalty bonuses

Players who are in a slots site’s loyalty program can receive bonuses for doing so. The best slots sites have bonus features for loyalty members boast rewards that include cash back on deposits, free spins, and other perks that non-members do not have access to. This is another online slots bonus that is great for players who play slots frequently. It is also great for players who are loyal to one site above the rest.

What are wagering requirements and how do I calculate them?

Wagering requirements are what players have to overcome when taking advantage of an online slots bonus. They are the amount a player needs to wager to be eligible to withdraw the funds from a bonus along with their initial deposit. Calculating these bonuses is straightforward in most cases. However, it is important to check the terms and conditions of the site you are using to make sure that you are calculating correctly.

For example, let’s say that a player receives a £100 bonus after making a £100 deposit, and there is a 5x wagering requirement. That player would need to wager 5x the £200 in their account after their deposit and bonus. Therefore, the wagering requirement for that player would be £1000. Be sure to also make sure you know what time period the wagering requirement is over. If there is a 30 day wagering requirement, your wagers need to take place during that time before your bonus expires.

Top 2 best slots bonuses


Casimba has a truly impressive online slots bonus, to the point that they are the best slots bonus around. The site offers a massive £6500 in bonus funds to new players, in addition to 125 free spins. That combination leads to a tremendous opportunity for players to rack up funds and earn a profit from the site. Of the £6500 in total funds allocated in the Casimba bonus, £5000 of them come on the first deposit. There will not be a rival to that impressive amount.

Dunder Casino

At Dunder Casino, players can get another elite online slots bonus. In this case, they can get up to £600 in additional funds along with 200 free spins. What is great about Dunder is the fact that they have a huge selection of games to go with that excellent welcome bonus. The site boasts over 1,000 games to choose from, with a great selection of slots for players to use their funds on. It’s certainly one of my favourite new slots sites open to UK residents.


How do I use an online slots bonus?

How to use a bonus at an online slots site depends on the rules of that particular site. Generally, a player will want to sign up for their slots site of choice, make an initial deposit using the corresponding promo code, and start playing using their bonus funds.

What kind of slots bonus is right for me?

The kind of slots bonus that you will want to use depends on what your financial needs are. If you prefer to play lower stakes slots, you will prioritize a higher percentage bonus. Meanwhile, when you want higher stakes, the bonus with the highest maximum bonus amount is what you are looking for.

What is the best way to play through a wagering requirement?

Playing the same way you normally would is the best way to get through your wagering requirement. Changing your wagering strategy can negatively impact your ability to get through the requirements with your funds in tact.
