Sign-Up Bonuses and Wagering Requirements

Online casinos use bonuses as incentives to encourage players to sign up, deposit money and keep playing with them. 

There are a variety of types of online casino bonuses including welcome bonuses, matching deposit bonuses, percentage deposit bonuses, reload bonuses, loyalty bonuses, and high roller bonuses.

It is worth investigating different types of bonuses to get the best value for your money.  Keep in mind though that online casinos will never simply give away money for free and that you should always read the bonus terms and conditions before you sign up for it. 

Most all bonuses are linked to a playthrough requirements or wagering requirements, which means you will have to wager the bonus by a certain number of times before you will be allowed to make a withdrawal. 

Understand the playthrough requirement (wagering requirements) before you sign up, especially if the bonus deal sounds too good to be true.

Types of Bonuses

Welcome, New Player or Sign-Up

The New Player, Welcome or Sign-Up Bonus is often the most generous bonus you will come across, as this is the online casino’s way of enticing you to sign up with them. Do not sign up with a casino that only offers a good welcome bonus, however, rather go for one that spreads out their bonuses throughout the spectrum. Welcome Bonuses can come in the form of No Deposit Bonuses, Matching Bonuses and Percentage Bonuses.

No Deposit

With this bonus and one of the best bonuses the online casino is giving you a chance to try their casino games free of charge without having to make a deposit up front. You are able to win money while playing with the No Deposit bonus at the casino.

Matching Deposit

This is where the casino matches the amount you deposit with them, up to a certain amount. If they offer a 100% matching bonus up to £100, it means that they will match you dollar for dollar and you will get £200 to play with when you deposit £100.

Percentage Deposit

While this bonus is not as great as the no deposit bonuses, the casino still offers to pay a percentage of the money you deposit with them. If they offer a 50% percentage bonus and you deposit £100, the casino will add on a generous extra £50 to your bankroll.

Reload

Reload Bonuses exist to keep regular customers interested in returning to the online casino and making further deposits. These bonuses are similar to the welcome bonuses and are usually either Matching Deposit Bonuses or Percentage Deposit Bonuses. Some casinos offer a monthly Reload Bonus but it does vary from casino to casino.

Loyalty

Most online casinos have loyalty clubs and VIP programs that rewards players every time they place a bet.  You are usually signed up automatically and earn points as you go along, climbing VIP levels according to how much money you deposit with the particular casino. Once you reach a senior VIP level, you will be offered special Loyalty Bonuses, which are more lucrative than normal Reload Bonuses, to reward you for your patronage.

High Roller

Just as casinos reward players who spend plenty of money with them over time, they also like to give something extra to those who like to splurge on big one-off deposits. They usually offer a Percentage Bonus for large deposits over £500 or £1000.

Refer-A-Friend

Some online casinos offer a refer-a-friend bonus, which you can take advantage of by successfully inviting your friends to play online. Each time you refer a friend, you will receive a free bonus.

Free-Trial No Deposit

Bonus money is for use in the casinos only, and cannot be cashed out nor can the winnings. Players receive a free bonus to try out the software and games without making a deposit. It's also to see if this casino is where you want to play.

Cash-Back

Cash-back bonus basically gives the players some of their gambling money back to them. The money is awarded back to players who have lost during their gambling sessions. Casino deposit bonuses are great, but if you’re a big time player who wants to extend their playing time, the Cash back bonus may be the way to go. This is how it works, if you lose £500, you'll get £100 back if you were on 20% Cash Back bonus. If you have a positive balance, you won’t get the cash back.

Payment Method

Casinos offer a range of payment methods through which players can deposit and withdraw their money. Some sites want to encourage players to use a certain payment method (such as NETeller, Skrill and many more) and therefore offer players an extra percentage bonus simply for using these methods.

 

Lastly, online casinos may limit how much you can withdraw after you’ve taken a bonus. This happens more often with the no-deposit bonuses offered; with these offers, the player hasn’t even had to deposit any of their own money. Understandably, the casino then limits just how much the player can withdraw. As always, you’ll find this restriction (and maybe some new ones not mentioned here) in the “Terms and Conditions” or “Rules”.

Knowledge is key; the more you know, the less chance you have of running into problems. Good luck!
