How Slot Bonuses Work
Why do slot sites give money away? The answer is – they don’t. Slot bonuses are made to attract customers’ attention with the promise of free money, but it is not so easy to really get it.
This is not an illegal practice; bonuses just come with their conditions and restrictions. The problem with online gambling, bonuses, promotions, and giveaways is that they come with high wagering requirements and other conditions, making it difficult to benefit from them. So, if a casino offers a slot bonus of £100, the customer will have to accept that they may get £5, £10 or £300 in the end, depending on the parameters and the way they wager.
Key Principles of Slot Bonuses
Even if a slot site offers a great first deposit bonus, users must not make a deposit only to claim it.
- The Terms and Conditions must be read very carefully.
- There is no free lunch; no slot site will give away money for nothing.
What is a wagering requirement?
Before diving into the different types of online casino bonuses, let’s clarify what a wagering requirement is. Wager requirements, sometimes referred to as rollover requirements are basically the conditions a user needs to fulfil to withdraw the money won from a bonus. Wager requirements are expressed in numbers, which tells you how much you need to wager to convert the bonus money to real cash. Because of this scheme, slot sites are not going broke while giving away bonus money for free. The wagering requirements are not always there, but the vast majority of bonuses do have them.
Types of Casino Bonuses
In the next section of this casino bonuses overview, we will look deeper into the different categories casino bonuses fall into. Most of these are quite popular among online casino sites.
This is a welcome bonus for all new depositors at the slot site. It is usually the largest bonus that gets the most attention at a slot site. The message of a casino sites welcome offer is what gets communicated everywhere, in the emails, banners, and ads. The idea is to give users an incentive to sign up and make a deposit. Usually, a welcome bonus includes both free spins and deposit bonuses in various matches. The match rates vary quite a lot; they can be anywhere from 50 to 200% of the deposit where we consider 100% and above to be good.
This type of bonus is a percentage of the initial deposit a user can receive on top of their bankroll. For example, if the bonus is a 50% match bonus, and the deposit is £100, the online casino will add £50 to the user’s bankroll as a bonus.
Free spins are one of the most popular online casino bonuses. It is targeted not only to existing customers but new members as well. This bonus gives them all the opportunity to play and win without risking their cash. The offer works in a way where the slot site hands out free tries on a defined slot machine where you as a player, must wager the spins a few times with the possibility to keep all winnings.
No Deposit Bonuses
Many casinos have chosen to offer new players a so-called no deposit bonus, which means that players receive a slot bonus immediately after they register without requiring that the player first needs to make a deposit. This bonus allows the player to try on the casino game environment before making their first deposit. A no deposit bonus can consist of a small amount, usually 5-10 pounds, which you can play any casino game, or you will receive several free spins that apply to a selected slot machine. A No Deposit Bonus often has quite hard demands when it comes to wagering of profits. There is normally also a maximum amount that can be deducted from the winnings earned when playing for a no deposit bonus.
If a bonus encourages players to add new funds to their account, it is considered a reload bonus. This offer is a way to keep customers coming back even after they have just lost their money. They get a special match bonus if they reload their account. Usually, the amount is a percentage capped at a specific amount.
Cashback is a rather new bonus form for casinos and was previously common to receive when playing sports or poker. Cashback means that you get some of the losses that you’ve had over a period, one day, one week or a month, back. It is common for a casino to pay 30 percent of players’ losses in one week. For example, if you lose £300 in one week, you get a cashback of £90, which gives the player a new chance at the slot site.
Something quite unusual but as some casinos still offer is that players get a portion of the casino’s win back in the form of cashback. This means that the more you play for a week, the greater the cashback you get from the casino, whether you win or lose. Most cashback has a turnover requirement, which, however, is usually quite low. There are also casinos offering their player’s completely free cashback.
Slot site bonuses are great and can also be quite fun if one follows the key principles they come with. For this reason, it is imperative to read and understand the wagering requirements well and to be able to calculate the real value a bonus has. If the slot site of choice does not offer a good welcome or first deposit bonus, users can always contact customer support for a special offer. The support agents can give special online betting bonuses, especially to customers depositing a larger amount of money. The final advice we would like to give our readers is to contact the cashier department before every next deposit and carefully read the wagering requirements.
