What Is an Online Casino Bonus?

casino bonuses

Bonuses give you extra money in the form of cash prizes or free spins, depending on the type. You can play for longer without using more of your own cash and try your luck with bigger stakes due to having access to more funds.

Many different types of bonuses are available. Some are for new players who sign up for a casino site for the first time, and some are for existing players.

Whilst casino bonuses vary in their type, they work similarly when it comes to claiming them. Each bonus has a set of rules that must be followed during the redemption process. This is known as the terms and conditions, which we will go into detail later in this guide. The rules include points such as making a minimum deposit requirement, a validity period, and eligible games.

Casino bonus offers are completely legal to claim and come with a multitude of benefits that make them so popular. Casinos that offer them are licensed by a certain Gambling Commission and give you the opportunity to try new games, increase your chances of winning, extend your play time, and give you access to additional funds. Some bonuses allow you to double or even triple the amount of your deposit.

Types of Online Casino Bonuses

Types of Bonuses

In this section, our Slotsjudge experts have researched and detailed the different online casino bonuses you can claim. Make sure to read through the information below to see what features and benefits they provide before deciding which bonus is right for you.

Casino Sign up Bonus

Casino sign-up bonuses come in various forms, including free spins and bonus credits. They are often referred to as online casino welcome bonuses or first deposit bonuses and are available to new players who have not deposited yet. It can be a fantastic way to kickstart your gambling journey, and players usually activate them by entering a sign-up bonus code during registration, or by opting-in through a casino account. Bear in mind that this type of bonus can only be claimed once.

Usually applied to selected slots, the first deposit bonus can provide extra opportunities to win and allow you to explore different games. However, various bonus policies may have restrictions impacting particular titles like live dealer tables and commonly are applied to slots. It is also worth keeping in mind that specific withdrawal requirements may apply.

No Deposit Bonuses

No deposit casino bonus is a great way to try out a new casino without spending any of your own money. At Slotsjudge, we love these bonuses as they are available to both new and existing players and usually come in the form of free spins or bonus credits. Players typically need to enter a code to redeem a no-deposit bonus at a casino. Still, it is worth bearing in mind that there is an expiry date connected to these types of benefits.

Casino Deposit Bonuses

Casino deposit bonuses are the most common promotions available to all players. These bonuses are activated on deposits beyond the first one, and provide a great opportunity to extend your gameplay on an ongoing basis.

Each deposit bonus amount is determined by a match percentage, which can range from 25% to 100% on average. These bonuses can be used on a wide range of games, including popular slots and classic table games.

Free Spins Bonuses

Free spins are amongst the most popular casino bonus types in the industry. These might include a welcome bonus, part of a deposit match bonus, or a no deposit bonus. The main attraction with these offers is that they are designed exclusively for slot games. Free spins allow you to experience the thrills of slot games and boost your credit amount for further play.

Casino Cash Bonus

Some sites can offer players a certain cash amount as a bonus. Usually, it’s a no-deposit offer received upon meeting a particular requirement, such as registration or verification. The cash amount is credited to the bonus balance, after which players can play with it in qualifying games to meet the rollover and withdraw funds after.

Cashback Bonuses

If you like the idea of getting a portion of your net losses back, then you will enjoy the perks of cashback offers. These bonuses vary at different casinos, but are designed primarily for players with a substantial deposit history.

Cashback casino bonuses are particularly common on live dealer games like blackjack, roulette, and baccarat. The percentage of cashback can vary widely, typically ranging from 5% to 40% on average. It can also be determined by your VIP or loyalty level if you are part of a program.

Reload Bonuses

You can redeem these bonuses using a bonus code, or by opting into a promotion on site. Available daily, weekly, or monthly, the reload bonuses are similar to a welcome bonus you receive as a new player. Casino reload bonuses are an excellent perk for existing players willing to gain additional funds to their accounts.

Exclusive Bonuses

Exclusive casino bonuses offer unique benefits such as gifts, event tickets, and birthday bonuses. These personalised rewards can enhance your gaming experience and are often awarded randomly to recognise your loyalty, making your time at the casino even more enjoyable.

Live Casino Bonuses

Live Casino Bonuses offered by online casinos for their live tables section, such as blackjack, roulette, baccarat, and a range of game-show-style games. These offers are available to both new and existing players depending on the casino site you choose.

VIP Casino Bonuses

VIP casino bonuses are often known as high-roller bonuses and are claimed by players who enjoy depositing substantial amounts of cash. These bonuses offer an exclusive online casino experience and come with higher maximum bonus limits that exceed regular bonuses, such as €1,000+. As a high roller, you can take advantage of these big-money offers and use them on large-bet games with advanced table limits. In most online casinos this type of bonus is available only as a single-time offer.

How to Choose the Best Online Casino Bonus?

Our team of experts constantly updates lists of the best casinos. We use a variety of ranking factors and industry knowledge to pick out the top casino bonus sites for our visitors. In the list below, you can view some of the bonus qualities that we look for to filter out the top promotions for you.

  • Wagering Requirements: Crucial part in regulating how many times you must bet the bonus amount, designed to prevent immediate withdrawals of bonus funds. Typical wagering requirements usually range from 20x to 60x the bonus, though some casinos may vary based on the bonus type.
  • Expiry Period: Longer length bonus durations and expiry periods that give you enough time to use the bonus and meet any wagering conditions. We try to avoid 24-hour bonuses and look for offers that are valid for 3-30 days.
  • Maximum Bet: Don’t lose bonus winnings by exceeding the allowed bet amount. Staying within this limit helps meet wagering requirements safely and secures your promotional funds.
  • Minimum Deposit: Desirable minimum deposit limits that don't break the bank and give you flexibility to claim a bonus that suits you. The average minimum deposit is €20.
  • Eligible Games: Each online casino dedicates different games for their promotions. We prefer those that let you choose which games you want to play, rather than being restricted to one or two titles.
  • Win Limit: Dictates the maximum amount you can withdraw from bonus winnings. Read through the bonus’s Terms & Conditions to understand the maximum threshold.
  • Payment Method: Flexible and convenient payment methods that qualify your deposits to claim a bonus, including debit cards, prepaid vouchers, and e-wallets.

Tips to win with Casino Bonuses

This section of our guide is dedicated to key findings by our expert team, offering a list of tips to help you get the most out of casino bonuses.
  • 1

    Find the Best Offers

    Spend time finding and researching the best offers. The market is full to the brim with attractive promotions of all different types and sizes. Don't rush and ensure you are opting for the best bonus that suits you, your playing style, and your budget.
  • 2

    Time Your Bonuses Strategically

    With a bit of strategic timing, you can get the best casino bonus at the right time. If you're close to a particular holiday season, such as Christmas, you will find that websites provide more generous offers. Plus, if you want to play a specific game like roulette, wait until you're ready to play before redeeming your offer.
  • 3

    Manage Bankroll Smartly

    A smart approach to bankroll management will ensure you not only play the games you love responsibly but also makes certain that your funds last longer. We recommend spreading your bonus money and wagers evenly to avoid busting your budget in the short term.
  • 4

    Choose Your Game Carefully

    Always look at the online casino games lobby before you sign up for a bonus to make sure the games you want to play are there. Not all casinos have the same games or software providers, which can leave you disappointed if you're looking for a specific slot or table game variant.

Why You Can Trust Slotsjudge in Selecting a Promotion

Our team not only shares a rating of top bonuses but also explains this choice and shares the results of the personal tests. We consider our own experience and players’ feedback, which guarantees transparency and objective results.

Independent Expertise

Our review platform is supported by a team of knowledgeable industry experts who provide impartial advice. Their extensive experience ensures that the recommended casino bonuses are based on merit and value, rather than any bias.

Testing

Each casino bonus undergoes a rigorous review process, including real-money testing and a detailed analysis of the terms and conditions. This ensures the information is reliable, and that the bonuses are genuinely worth considering.

Players Feedback

We incorporates user reviews into its evaluation process, providing a balanced view of the strengths and weaknesses of various bonuses. This helps create a more accurate picture of what players can expect and value.

Is it Possible to Receive Multiple Bonuses?

In most cases, casino rules prohibit getting several promotions at a time. When this condition is specified in the terms, you may lose your offer by activating another bonus. However, there are some exceptions, which are always explained in T&Cs. Some sites may allow players to have several promotions at once, which is their special highlight. Furthermore, casinos with a complex system of daily, weekly, and monthly cashback may allow users to activate all the 3 types and wager them independently.

Bonus Terms and Conditions For Casino Players

All casino bonuses come with specific terms and conditions that you need to understand fully, as any violation of terms and conditions might lead to loosing the bonus funds. By reviewing these terms, you can make informed decisions and avoid any hiccups that might affect your overall play session. Reading through the Terms & Conditions prevents you from encountering unwanted outcomes.

Type of Bonus

There is a myriad of bonuses online casinos offer. Generally, they tend to stick with free spins or cash prizes presented as a reload, welcome, or high-roller promotions. All of those vary depending on your deposit history and events like Halloween or Christmas. Make sure you drop by the Promotions section of online casino websites to redeem the bonuses.

Minimum Deposit Required

Each online casino bonus will ask for a minimum investment of real money from you when redeeming a bonus (except for no deposit offers). The deposit value is often small (at around min deposit of €20) on average, and is what activates the promotion.

Wagering Requirements

The wagering requirement is one of the biggest talking points of online casino offers. It is given as a multiplier (such as x40 wagering on bonus) and represents the total amount of money that must be wagered before you can cash out any winnings. When you make a deposit, ensure that you fully understand whether the wagering on bonus requirement applies to just the bonus funds (or spins), or the deposit and bonus total combined. Top online casino sites are usually the ones with the lowest value of around 25x or below. Another point you must note is whether the bonus funds contribute to wagering or your deposited cash.

Game Restrictions

If you claim free spins, then your bonus will be restricted to online slots only. Each offer will specify which games, categories, or software providers you can use your bonus on. Live dealer games are generally excluded from most generic casino promotions. You will often find the best casino sites will provide greater freedom and fewer restrictions when it comes to bonuses.

Maximum Bet Limit

One way that online casino sites limit the amount you can win is by restricting your bets. Ensure that you note the max limit per bet (such as €5) so that your wagers are eligible and qualify towards any wagering conditions. Online casino sign up bonuses don't often have a max bet limit, but free spins and no deposit offers do.

Win Limits

Many bonuses, such as free spins and no deposit offers, will specify a maximum bonus win limit on any winnings you make from using the bonus. Casino welcome offers and other bonuses with this condition limit your potential win amount to the value specified by the casino, such as €100. Any amount over this will be null and void and removed from your account.

Expiry Period

Make a note of the expiry period or bonus duration before claiming. Almost all casinos have this rule and is the amount of time you have to use the bonus and meet any wagering requirements if required. If you fail to do so, you risk losing the bonus and any winnings will be forfeited and removed from your account.
