There are loads of different types of sign up offers, all of which can be unlocked and used in different ways. The basic instructions are to sign up, opt into the bonus and then make a qualifying deposit.

Opt to become well informed first.

Types of Welcome Bonuses

There are many different welcome bonuses for you to choose from if desired. Have a look at the ones below:

Matched Deposit Bonus

Deposit match bonuses are often used by online casinos with a sign up bonus. New players can sign up, make the first deposit to an online casino and claim twice the rewards with this type of reward. An example of this would be a site advertising a 100% matched deposit worth up to $100. Players can deposit £100 in order to receive an extra $100 in promotion funds, giving them $200 to play with.

match_bonus-1

How to Find Matched Deposit Bonuses

The most widely offered online casino deposit bonus in the online casino realm is perhaps the cash match bonus. On shopping around for bonuses, you’ll typically notice that casinos will advertise ‘$X free.’ Although the term ‘free’ is usually considered to be the magic word when buying anything, this bonus isn’t actually free per se.

How to Use a Matched Deposit Bonus

Deposit match bonuses are often used by online casinos in sign-up offers. New players can sign up, make a first deposit through your preferred payment method such as Cash App or Visa, and claim twice the rewards with this type of reward. An example of this would be a site advertising a 100% matched deposit worth up to $100. Players can deposit $100 in order to receive an extra $100 in promotion funds, giving them $200 to play with. 

match_bonus-1

Matched Deposit Bonus Terms

In most cases, you’ll have to deposit money prior to gaining the reward. Whether you’d like to deposit $500, $1000, $2000, or more is up to you, but generally, you’ll find that the greater the amount you deposit, the more bonus money you’ll be able to acquire. However, this will not only be dependent on the amount you deposit but also on the match percentage.

Percentage Deposit Bonus

A percentage deposit offer is similar to a deposit match offer. The difference is it will be a lower percentage than 100%. For example, the offer might be a 75% matched bonus worth up to $225. Players will need to deposit at least $300 in order to claim the full reward, giving them a total of $525 to play with. 

How to Find a Percentage Deposit Bonus

Often, these are part of a multi-stage signup bonus casino offer, giving players multiple bonuses for their first three deposits. These percentages differ from casino to casino. So, for example, you might come across an online casino with a sign up bonus of 50%, whereas another casino will opt to offer a better percentage of 100%, while another competitor may offer 150%. 

How to Use a Percentage Deposit Bonus

If you opt to claim the welcome bonus with the catch match percentage of 100% and you deposit $100, you’ll be able to double your cash to $200. However, before making your decision, we recommend that you always read the fine print before you cash in on your bonus, as most of the time, you’ll have to meet the wagering requirements before you withdraw your winnings

Free Spins

Free spins are often included in new player bonuses either on their own or combined with a matched deposit offer. This bonus essentially gives you the freedom to play welcome bonus slots without risking your own money. Free spins are often available on selected slot games and are one of the easiest online casino sign up bonus offers to use.

How to Find Free Spins Offers

Free spins are offered by most gambling sites, either as an online casino sign up bonus or regular player offers. If you’re looking for the best free spin welcome offers, you can take a look at our list of the best offers.

How to Use Sign Up Free Spins

For example, 100 free spins will allow the player to spin a selected slot 100 times without charge. Players can still win while using free spins, but the winnings will be paid out in funds that usually can’t be withdrawn.

Crypto Welcome Bonus

A crypto sign-up offer is a special gambling site promotion available to users who make a deposit using cryptocurrency. The number of people using cryptocurrency for online payments has increased over the last few years, and many online casinos now accept the most popular types, so it’s relatively easy to find BTC casinos and ETH casinos.

How to Find Crypto Welcome Bonuses

Crypto sign up offers are only available at online casinos that accept cryptocurrency payments. While this form of online payment is more popular than ever, it’s still not accepted by all sites. You can find the best crypto casinos and crypto bonuses here on our site.

How to Use Crypto Welcome Bonuses

Some gambling sites offer bigger rewards to players making deposits with crypto. For example, a site might reward players with a matched deposit offer worth up to 1BTC, which would be one of the best online casino welcome bonuses. 

Mobile Casino Welcome Bonus

Online casinos are no longer only available on desktop. Most sites now offer full compatibility with mobile devices, including smartphones and tablets, and some even offer downloadable apps for even great convenience. This service extends to casino online sign up bonus offers too.

How to Find Mobile Casino Sign Up Offers

Whether you are looking for Android casino games or iPhone casino games, most online casinos offer a mobile casino welcome bonus whenever you sign up with your device. This is a great way to sign up and claim an excellent bonus while on the go.

How to Use Mobile Casino Welcome Bonuses

If you enjoy mobile gambling, you’ll love mobile sign up bonuses, which offer special rewards to mobile users. When you log in using your mobile or download the gambling site app, you’ll be able to claim a special welcome offer that allows you to play your favorite casino games while out and about. 

Make Your Own Bonus

Other than the Cash Match Bonus and the Staggered Cash Match Bonus, you’ll also be able to find the less popular, but perhaps more lucrative Make your Own Bonus.

How to Find Make Your Own Bonus Offers

This type of bonus will not fundamentally depend on the amount you deposit. Nonetheless, a minimum deposit will be required in order to cash in on your bonus. When receiving this kind of Online Casino Welcome Bonus, the casino will allow you to play with the amount of credit it gives you within a certain amount of time.

How to Use Make Your Own Bonus Offers

The free money you’re given will allow you to make the most out of the time that has been allocated to you. You get to pocket the amount of money you’ve won in that period, and whatever you win will be considered your welcome bonus. Yet, if lady luck isn’t on your side and you don’t happen to win anything, the majority of online casinos out there will offer you a consolation prize. Therefore, it’s a win-win situation if you opt to cash in on this type of casino online sign up bonus instead.

Sign Up Offer Terms and Conditions

All bonuses come with terms and conditions that state how they can be used. Before signing up and taking part in a casino promotion, you should make sure you understand these fully, as failing to follow the terms can result in you missing out.

Sign Up Bonus Casino Wagering Requirement

Wagering requirements are commonly used by gambling sites when offering an online casino signup bonus, and you’ll need to complete the wagering requirement before you can withdraw the full reward as cash. This will be shown as 10x, 20x, or 30x, for example. You’ll need to wager the bonus the set amount of times before you can withdraw it as cash.

make_a_deposit

Maximum Win Cap

Some bonuses may come with a limit on how much you can win from them. This is particularly common with the best online casino no deposit sign up bonus offers. This is because casinos want to avoid giving away free money. Always check to see if there is a limit on how much you can win before you play to avoid disappointment. 

withdrawl-1

Time Limits

Most bonuses have a limit on how long you have to use them. Once you’ve unlocked the casino online sign up bonus, it will normally expire after a set amount of time. This could be a week, a month, or just a few days. It’s important to check this before playing. Otherwise, you could lose out on your bonus.
