Casino Bonuses 2025

What Are Casino Bonuses?

A casino bonus is a type of promotion that gives players rewards such as free spins, casino credits, or free bets when they follow a set of instructions. These rewards are commonly offered as incentives to new players when they join a gambling site and make a real money deposit.

How Do Online Casino Bonuses Work?

An online casino bonus works through a straightforward process: claim, use, and withdraw. To claim your reward, you must usually create a new account at a casino, enter promo codes, and make a real money deposit.

Once you’ve received your reward, you can use it at approved casino games. These promotions often come with terms and conditions, such as wagering requirements, expiry dates, and other restrictions that impact how you use them. As soon as you’ve met all the requirements, your funds will be converted to real money, which you can withdraw from your account.

Are Casino Bonuses Worth It?

Casino bonuses are often worth claiming because they boost your playing potential without depositing extra funds. However, not all bonuses were created equal. Some have restrictive T&Cs, such as high wagering requirements and low win caps, whereas others offer low-value rewards. While there are plenty of worthwhile deposit casino bonuses at our recommended casinos, we always recommend reading the terms and conditions before claiming any promotion.

Different Kinds of Online Casino Bonuses

While researching the top online casino bonuses, our experts found a variety of different options. Each type of casino promotion has a unique purpose, whether it’s encouraging a player to sign up or gaining the loyalty of existing players. We’ve explored the most common offers below to help you understand what you can expect from each promotion.

Other Popular Options

As you explore the best online casino promotions, you might notice that some offers appear unfamiliar. Casino offers can vary significantly based on factors such as your country, game providers, and the type of casino.

Casino Bonuses by Country

Your country’s gambling regulations can heavily influence the types of casino offers you receive. Some EU countries, such as Sweden, have strict regulations that forbid ongoing promotions and limit sign up offers to SEK100 (€8.85). Other jurisdictions, such as the US, UK, and Asia, have fewer regulations, allowing players to receive large rewards and regular promotions.

Casino Bonuses by Software

Many casinos vary their promotions depending on their most prominent software developers. Sites with closer partnerships with renowned slot developers, such as NetEnt, are more likely to offer free spins that can be used with those games. Similarly, sites with a large live dealer library provided by a company, live Evolution Gaming, will commonly offer matched deposit or free bet promotions.

Best Online Casinos With New Casino Bonuses

During our research, we’ve found that new casinos typically offer bigger welcome packages than established sites as a way to attract new players. These welcome packages include increased matched deposits and larger free spins. Examples of some of the best new bonuses include:

Special Offers

While evaluating different online gambling sites, we found other promotions that don’t fit the typical bonus structure. These special offers are typically exclusive to existing players and have alternative claiming requirements:

• Referral Bonus: These promotions are awarded to players who successfully refer another player to the site. They can offer casino credits, FS, or free bets when the referee signs up and makes a real money deposit.
• Timed Promotions: Some casinos offer players small daily, weekly, or monthly promotions that attract them to log in each day. Common examples of this include daily prize wheels and monthly raffle draws.
• Game-Specific Bonuses: These promotions involve free games in which existing players can participate. They typically offer small rewards and low odds of winning.

How to Choose the Best Online Casino Bonus

With so many options available, it can be hard to know which offer is best for you. To that end, we’ve provided some helpful tips that you can use when picking your next bonus:

• Consider Your Playing Style: The best way to narrow your search is to look for promotions that fit your playing preferences. For example, if you’re a slots player, you won’t get much fun out of a live casino bonus.
• Look for Mobile Gaming Options: The top sites give mobile casino bonuses that reward users for downloading and using their apps. These bonuses offer great rewards, such as FS and free bets, that can be used on the go.
• Calculate the Value: When choosing a specific type of bonus, look for the one that offers the best value for money. These higher-value promotions will increase your initial deposit and give you additional playing time.
• Evaluate the T&Cs: We always recommend reading the T&Cs before playing to ensure you’re up to speed with what’s required. Casinos with transparent and easy-to-understand terms and conditions are usually your best options.

Casino Bonus Terms & Conditions to Watch Out For

All promotions have terms and conditions you must follow when claiming and using them. Many players skip over these T&Cs, but reading through them will help you avoid any nasty surprises.

• Expiration Dates: Even the best online casino bonuses will expire if you don’t use them fast enough. Once the expiration date has passed, you will lose all rewards that haven’t been converted to real money.
• Game Restrictions: Some rewards can only be used with specific games and aren’t free to be used anywhere at the casino. This is a common condition of free spins promotions.
• Maximum Wins: Many promotions have a maximum win limit, preventing you from winning too much with your bonus. Once the wagering requirements have been met, all winnings over this limit will be removed from your account.

How Do Wagering Requirements Work?

Based on our experience, the most important bonus condition is its wagering requirement. Also known as playthrough requirements, these terms dictate how much you need to use your rewards before they can be withdrawn.

For example, your €20 bonus comes with 40x playthrough requirements. This means that you need to play €800 worth of casino games before your rewards are eligible for withdrawal. The lower the wagering requirements, the better your chance of winning real money.

No Wagering Bonuses

Arguably the best casino bonus you can get is the no wagering offer. These promotions have no wagering requirements, giving you instant access to your winnings. Casino offers without wagering are hard to find and typically provide lower rewards than traditional wagering promotions. While they may not be the biggest casino bonus offers, they’re one of the most valuable and remain a popular option among players around the world.

How to Calculate Casino Bonuses Online

When evaluating the best bonuses, it’s essential to grasp the actual worth of each offer. To assist you in determining the value of your online casino bonus, we’ve prepared a useful calculation guide.

Deposit Free Bonuses

These promotions are the easiest to calculate as there is no deposit to consider. As soon as you complete the verification requirements, the full value of the bonus is credited to your account.

Bonus = Reward

Deposit Casino Bonus

The value of your deposit offer will vary depending on the match percentage. The higher the percentage, the more your deposit is worth. For example, a €10 deposit with a 100% bonus will give you an extra €10 in casino credits, but a 200% offer will give you an extra €20.

Deposit * Match Percentage / 100 = Reward

Free Spins Casino Bonus

The worth of your FS bonus will change depending on the number of spins you receive and the value of each spin. If you receive 50 FS worth €0.10 each, the total value will be €5, whereas 10 FS worth €1 each will give you a value of €10.

Number of Spins * Spin Value = Reward

Cashback Casino Bonus

Your cashback rewards depend on the amount and percentage you lose during the allotted period. The best cashback offers will give you back a larger percentage of your losses, increasing the rewards you receive.

Let’s say you deposit and wager €100; if you lose 50% with a 10% cashback promotion, you’ll receive €5 back, but if you lose €40 with a 20% offer, you’ll receive €8.

Deposit Losses * Cashback Percentage / 100 = Reward

Loyalty Rewards

The hardest promotions to calculate are loyalty rewards, as they typically offer points in exchange for playing specific games, which can be converted into other bonuses. Every casino uses a unique points system, offering different point values for different games. Usually, the lower RTP games offer more points, while higher RTP games like blackjack offer fewer points.
