Understanding Online Casino Bonuses and their benefits

One of the most important aspects of any internet-based casino is the bonuses it offers. Nearly every casino offers its players the welcome bonus which, as the name suggests, is to welcome them to the particular casino’s web site. In this section, we set the record straight regarding the different types of bonuses, how they work, what benefits a player can draw from them and where to find the best casino bonuses for players from United Kingdom, Austria, Switzerland, Australia, Germany, Sweden, Norway, Finland and Poland.

https://www.gamblingmetropolis.com/wp-content/uploads/2013/08/gonzos-quest-poster-350x332.jpg

Why casino bonuses?

Bonuses are very important to players. They basically give you more money with which to play. This means you can play more since you have more cash and this really improves your chances of winning.

The best way of taking advantage of the top casino bonuses is by finding a promotion or an offer that best suits you. Also ensure that you have checked the terms and conditions of a given bonus well in advance. Provided you meet a casino’s requirements regarding a particular bonus, you could benefit from extra casino cash, free spins as well as an opportunity to win even bigger prizes.

It’s also a great way to get more play time and try out all the exciting video slots from the most popular casino providers such as Netent, Microgaming and Playtech.

Different types of bonuses

There are mainly four kinds of bonuses offered at casinos and they are deposit bonuses, free spins, bonus cash and free play.

Deposit Bonus

This refers to a bonus that can be claimed by players if they make deposits. It normally has a specific percentage and it is also capped at a maximum value. A match bonus of 100% matches the entire bonus. If, for example, it is a 100% deposit bonus and with a maximum value of €200, players who deposit €200 will make another €200 in bonus credit.

Free Spins

This is normally forms part of welcome bonus that a casino could offer besides its other bonuses. For instance, a casino could offer its players a match deposit bonus and 100 free spins. This will give players 100 free spins on top of the deposit bonus. Players can use the free spins on certain games or on any games, depending on the terms and conditions of the promotion.

Some casinos will also offer their players free spins upon registration without any deposit required.

Free Bonus

This is a free chance to play that casinos give their players. For example, a casino could offer €10 freely upon registration. Sometimes, casinos offer this bonus to their existing players as well. Free bonuses gives you a chance to actually win without depositing any cash. In other words, you can play and even win for real money and not have to risk any of your own. Some casinos have wagering requirements in relation to the cash bonus.

The Free Play Bonus

Many casinos thank players for choosing them and not their competitors by offering them a gift to welcome them and a good example of such a gift is Free Play bonus.

This is similar to the cash bonus but instead you are given a large amount of play money with wagering requirements that you have to play for within a certain time frame. After the time has passed and if you’ve managed to win enough money, you can exchange that for a smaller sum of real money.

It’s a great way for the player to try out various games and still have the chance of actually winning some money.

How do online casino bonuses work?

The deposit bonus is the most common of casino bonuses. In it, the casino offers to match a player's deposit or deposits, up to a certain amount and at a given percentage. For example, a 100% match up to €200 means that if you deposit €200, you get another €200 in bonuses.

In order to earn the bonus, you will be required to make valid deposit and then bet a given amount of cash at that casino within a specified duration of time. Terms and conditions of these bonuses will vary a lot from a casino to the next.

Wagering requirements

How do wagering requirements work you wonder? A wagering requirement refers to a multiplier that shows the number of times you need to play through the bonus amount before being eligible to withdraw any winnings you receive using money awarded through the bonus.

In other words, you will not be able to cash out your winnings or the bonus before you complete the wagering requirements. All online casinos normally have certain requirements for their promotions. Also called terms and conditions, or just T&C, these bonus requirements let you know the bonus offer's parameters.

For you to know how a given bonus works as well as how to earn the bonus money, it is critical that you understand the requirements.

Conclusion

Online casinos make use of bonuses to attract new players and to reward loyal customers. You can use the bonus to play either on your laptop, smartphone or tablet PC and increase your chances of winning real cash.     Want more information about casino bonuses?
