Types of Casino Bonuses and Promotions

When you gamble or play online, you find many casino promotion categories. Each one works in a slightly different way. Before claiming an offer, you should know the types of online casino bonuses and what each one brings to the table.

Welcome Bonuses

A sign-up, or welcome bonus, is for new players who create an account and make a deposit. This type of promotion is usually one of the best in terms of match rate and amount.

It may be one large offer or a series of smaller ones to use across your first few deposits. Make sure to claim one of these when you make your first deposit.

Reload Bonuses

A reload bonus is for loyal customers to use after completing their welcome reward requirements. When depositing funds into an existing account, check if ongoing reload offers are available.

These bonuses aren’t usually as large as new player promotions. However, they still provide players with extra bankroll for real money games.

Game Specific Bonus Cards Bet Icon

Game-Specific Bonuses

Some offers restrict bonus cash to a handful of real money games when clearing wagering requirements. Free spin bonuses only work for slots, while other rewards may be exclusive to blackjack or live dealer games.

Some promos let you play any game you want to but have different rollover terms for each. Finally, some deals are only valid when playing on mobile devices.

No Deposit Free Chip Coin Stack Icon

No Deposit Bonuses

These bonuses give you a small amount of cash without the need to make a deposit. You’ll still need to sign up for an account, but these deals let you test the site and its games for free.

Most no-deposit offers may have higher than-average wagering requirements, which will make it harder for you to withdraw the bonus amount.

Referral Bonuses

One of the best ways a gambling site can promote itself is through its existing customers. Players who use an online casino referral bonus typically receive extra cash directly into their account. With a refer-a-friend bonus, the new and existing players benefit from the perks.

How To Calculate Online Casino Bonuses

When you start gambling online, you’ll see a lot of bonuses and promotions. However, deciding which are best is not a matter of finding the biggest payouts. Always read a casino’s terms and conditions carefully.

Match Rate & Max Bonus Amount

The match rate is the percentage at which your deposit gets matched — the higher the matching rate, the better the offer. If the deal matches at 300%, then when you deposit $20, you have an extra $60.

The bonus size is the number that follows the match rate. It’s the maximum amount of extra money you can get from an offer. For example, you may see a match rate followed by “up to $3,000.”

The higher number catches your attention, but if you don’t plan to max it out, this number matters less than the match rate. To get the entire $3,000 with a 300% match rate, you need to deposit $1,000.

Welcome Bonus Example: 200% up to $1,000

We strongly recommend you carefully read the terms and conditions of each casino bonus. That way, you know exactly what you’re getting into and the requirements you must meet when playing before you can cash out.

Calculating Wagering Requirements

Your wagering and rollover requirement, sometimes called “playthrough,” is the amount you need to bet before you can withdraw the casino bonus. They usually range from 20x to 50x, but it varies from offer to offer.

Wagering Requirement Example: $20 Bonus at 30x Rollover

Each bonus is a little different. Some have codes, some have specific terms, and some are short-lived. You’ll want to pay close attention when using promotions to ensure no surprises.

Bonus Codes

Bonus codes are a critical part of many online casino offers. Additionally, some bonuses don’t have codes but may require you to take another action, like contacting customer service or sending an email.

Using a bonus code is usually very easy. Log in to your account and head over to the cashier to make a deposit. Enter the coupon code accurately in the appropriate field, and you’re good to go.

Additional Factors

Some casino bonuses have 10 or more conditions built into the offer. The following factors are relatively common in many deals.

Game Restrictions

Some online casinos restrict which games go toward your wagering requirements. Slot machines may be allowed for an offer where they exclude table games.

Payout Speed Icon

Time Window

You may have a time limit to clear and use the extra cash. Many offers have a 30 to 60-day period, but a weekend bonus could end at midnight on Monday.

Free Spins

Some offers give you free slot machine turns. As long as you finish over $0, you get to pocket the winnings. It would be best if you used all spins before cashing out.

Can You Cashout The Bonus Money?

Keep an eye on what you’re able to cash out. The promotion amount goes into your bankroll to use while playing games online. You can always pay out winnings, but only some offers allow you to withdraw the funds given to you by the site.
