Another essential aspect compared to the CryptoLeo is the 25x wagering, which is easier for you if you’re a new gambler in online casinos.

Based on our experience, this type of casino bonus is designed for high-rollers because the maximum bonus amount from all three deposits equals $3000, and the minimum deposit is high. On top of that, the wagering is 40x and only a high-roller, seasoned player will know how to handle this complex playthrough. Where Does Boho Casino Shine?

With this info in mind, you should understand that the 40x wagering will be easy because if the bet is higher, the chances of clearing the wagering rise. On top of that, you will receive an additional 250 free spins with 35x wagering, so if you’re a slot enthusiast, you should visit IceCasino for the best online gambling incentive.

#5. Gxmble Casino: Discover the Best Online Casino Bonus for Low Playthrough

Even if you see Gxgmble Casino in the 5th place in our ranking for the best online casino bonus, you should understand that our ranking criteria are complex. Gxmble Casino is desirable if you want a low-wagering bonus or bonuses for existing players. One inconvenience that guided our decision to place this bonus on #5 is the €50 minimum deposit, which is high compared to many. However, note that Gxgmble casino will give you three deposits worth €150 with maximum bonus funds of €2500 and 5x wagering. We consider this bonus part of a high-roller agenda because players who play on a budget will not afford to pay €50 three times for a bonus, and we will not encourage you to do so. Where Does Gxmble Casino Shine? 

• Attractive low-wagering promo offer
• With the welcome package, you will test many new slots, including immersive video slots from Netent or Play’n Go Play.
• You can try over 400 live casino games.

Remember that the minimum deposit for the bonus is $30, which is higher than most competitors, but Slots Gallery has some perks that others, like CryptoLeo, lack. We refer to various payment methods, such as NeoSurf, EcoPayz, Bank Transfer, Skrill, Visa/Mastercard, Neteller, Bitcoin, etc. The only drawback is that you can wait for a cashout for up to three days. Explore the Slots Gallery’s best bonuses via Alexandra Camelia Dedu’s promo offer analysis. Where Does Slots Gallery Casino Shine?

We consider Verde Casino a top casino promo because it can be activated with a minimum deposit of 10 euros, which is rare. We make this statement because, compared to Slots Gallery or Gxmble, where you had to deposit €50, everything will suit you best at this casino, even if you’re a new, inexperienced player. At Verde Casino, you will receive a bonus of 120% up to €300, a standard amount, but you must be aware that the 40x wagering requirements will present you with a complex challenge. Where Does Verde Casino Shine?

Among the available slots, you can choose titles like Big Bass Amazon Extreme, Sweet Bonanza, Mustang Gold, Legacy of Dead, Big Bass Splash, and many more. When we tested the Jupi Casino bonus, we saw that the wagering is 40x, strengthening our opinion that this bonus is designed for high-rollers. Where Does Jupi Casino Shine?

How Different Types of Casino Bonuses Work

Learn how different types of casino bonuses work before claiming. This will help you leverage your bonus correctly and increase your chances of winning.

No deposit bonuses & free spins

No deposit bonuses are some of the most popular offers on our site. It’s not hard to see why since you only have to register on the no deposit casino site to start playing: the bonus is credited to your account instantly. You can find no deposit bonuses in various forms selected by KingCasinoBonus online gambling experts, including:

• No deposit free spins: Get free spins immediately after registration. You can use the no-deposit free spins to play your favorite slot games in a fixed amount of rounds. For example, a casino may give you 20 free spins in the form of a casino welcome bonus to use on any slot game after you register.
• No deposit bonus cash: With this no deposit bonus cash offer, the casino credits your account with free bonus money to use as you please once you register. For example, you can get a $10 no deposit bonus after registration. You can often use this to play all casino games, including slots and table games.

First deposit bonuses

The first deposit bonus is one of the easier bonuses to understand. As you can tell from the name, this is a deposit casino bonus offer you get after you make your first top-up on the site of the specified min amount. You may get 1st deposit bonuses like:

• A first match deposit match offer (most popular) – ranging anywhere from a 100% deposit bonus match to 500%.
• Free spins for real money bonus
• 1st deposit that kicks in a reload bonus
• Cashback bonus.

Welcome Bonuses

Welcome bonuses are offers you get for signing up on the platform. The welcome bonus is usually in the form of multiple match bonuses with extra spins, free live casino chips, or other extra perks. The goal of the sign up bonus is to get you to register and keep playing on the site. If you sign up on a top site selected by our experts, the welcome bonus package will commonly get you:

• $10 no deposit bonus
• 100% or 200% up to $1,000 or more for the first deposit bonus.
• Then you can get match percentage bonuses of up to your 4^th and even 5^th deposit.

Low minimum deposit bonuses

Typically, you’ll have to deposit around $20 to claim most offers on casino bonus sites, going up to $60. Low minimum deposit bonuses allow you to deposit less, starting from $1 and $5 to a maximum of $20 – best for players on a budget. Check the lists of bonuses we picked based on our in-house research if you want to make the lowest deposits at online casinos and claim bonus offers of attractive value:

• $5 deposit bonuses
• $10 deposit bonuses
• $20 deposit bonuses

How to Choose the Top Casino Bonuses for You

While searching for the best casino bonus offers, we realized it may be difficult for you to find the right one without these tips:

• Consider deposit amount: Earlier, we mentioned that most bonuses need a deposit to activate them. Knowing the amount you must deposit and if it suits your budget is extremely important because they can start from $10 to as high as $50. If you are on a budget, it is wise to choose low minimum deposit bonuses of $10 or less.
• Match to favourite games: Make sure the bonus the actual money casino offers can be used on your favourite games. Our research found offers tied to slots, while others were tied to table games. If you love slot games, it’s best to aim for bonus spins, as these are ideal for slots.
• Mind the wagering: The wagering requirement is a vital aspect of bonuses. It is also known as a playthrough requirement and shows how often you’ll need to wager a bonus before withdrawing your earnings. We will cover wagering examples in more detail later in this guide. Keep in mind to pick the lowest wagering.
• Check if games contribute: Play games that contribute to the wagering requirements. Slots are usually 100%, while other titles contribute as low as 10% or even 0%. Ideally, you want to play games that contribute more to quickly completing the wagering requirements and cashout.

Calculate Bonus Value and Cashout Potential

The question that’s on every player’s lips is whether you can win real money with an online casino bonus. Let us show you how to calculate your maximum cashout potential from the best casino bonus offers and determine the max win amount before you claim a bonus. Vital things to consider in calculating this figure

• Match Percentage
• Bonus amount
• Wagering requirement
• Game contributions

Keep reading as we uncover each of these and why they matter below.

Get the highest 1st deposit Match percentage

All the top bonuses we have come across are usually attached with a match percentage on your first deposit. This indicates the percentage the online casino is willing to match your initial deposit by. The higher this percentage, the more you can expect to get in bonuses when you make a deposit. Some of the common match percentages you’ll come across include:

• 100% deposit bonus: Here, the casino gives you 100% extra of any amount you deposit. So, if you deposit $100, you get an extra $100 to bet.
• 200% deposit bonus: This is another popular offer where casino players get 200% extra on any cash deposit. In this case, depositing $100 will get you an extra $200 to play with.
• 300% deposit bonus: With this matching percentage, the casino matches your deposit by 300%. So, if you deposit $100, you get an additional $300 to play.
• 400% deposit bonus: This is one of the higher bonuses, and the casino gives you x4 of your deposits, which is impressive. In this case, depositing $100 will get you an extra $400 to play with.
• 500% deposit bonus: The 500% deposit bonus is not as standard as we would all have loved – but it is available if you know where to search. Here, the online casino will give you x5 of any deposit you make. So, presuming you deposit $100, you get an extra $500!

As you can see, going for the most extensive online casino bonuses with higher percentages will leave you with more free cash to play games. Check our lists to find your best fit and attractive bonus terms!

How to calculate the bonus amount

The bonus amount shows the maximum deposit an online casino will match for you using the set percentage. For example, a casino can offer a 200% match deposit up to $2,000. This means that it will give you double any amount you deposit so long as it does not exceed $2,000. So, assuming you deposit $1,000, the casino will give you an extra $2,000 to play. But if you deposit the maximum of $2,000, the casino matches it and gives you an extra $2,000. Naturally, depositing $3000 will only activate the maximum bonus value of $2000.

How wagering requirements affect you

The wagering requirement indicates how many times you’ll need to play through a bonus before you can withdraw. We found that wagering requirements range from 10x – 60x, and in this case, the lower, the better. Our testers recommend visiting our unique list of the best low-wagering casinos because the bonuses are best suited for new and experienced players. How to Calculate the wagering requirement Our research showed that online casinos have wagering requirements to prevent money laundering. Shady players could claim deposits and withdraw funds without playing on the site if wagering did not exist. Let’s assume the 200% match deposit up to the $1,000 bonus from Rollino Casino example above is attached with a 20x wagering requirement. If you deposit $500 and get an extra $1000, you’ll need to wager the $1000 x 20 = $20,000 before you can withdraw. For example, if the wagering requirement was lower at 5x, you’ll need to play only $2,000 x 5 =$10,000 before withdrawing. In the case of free spins, you’ll only apply the wagering requirements to any cash you win using the free spins. Wagering Examples Ideally, you want to aim for 15x or less since it means you’ll get your winnings faster. Check out the table for examples of wagering requirements and how much you need to wager.

Check no wagering bonuses Some sites offer no wager bonuses if you don’t like the stress of completing wagering requirements. Get instant access to your bonus and claim your winnings as soon as they land in your account.

Game wagering contribution

As we mentioned earlier, not all games contribute the same way to completing your wagering requirements. If an online casino allows the contributions to be equal, it will be easier for players to claim bonuses quickly. While this is excellent news for players, it could cause the casino to lose money. This is why casino sites attach different contribution percentages to games. Average contribution percentages you can expect

• Slots: 0% – 100%
• Baccarat and Blackjack: 0% – 25%
• Poker: 0% – 50%
• Live Casino Games: 0%

Choose Deposit Bonuses for Games You can play with deposit bonuses on almost every game in an online casino. While this may be different depending on the casino you sign up at, you can expect to play with bonuses on:

• Online slots
• Table Games, including blackjack, poker, roulette, and baccarat
• Keno and Scratchcards

Slots Bonuses

Slots bonuses are used to play slot games, and they may come as free spins, bonus cash or a combination of both. Sometimes, the casino may limit you to a specific slot game, while in other cases, you can play slot games of your choice. Here are some top examples of these kinds of bonuses:

• 10 free spins on Book of Dead
• 20 free spins on Cleopatra
• 50 free spins on Mega Moolah
• 100 free spins on Starburst
• 100% up to $200 + 50 free spins on NetEnt slots

Table games bonuses

Table games bonuses are offered for you to use on table games like roulette, blackjack, poker, and roulette.

• $1,500 table games bonus
• $2,000 bonus on roulette
• $2,500 bonus on blackjack

Live Casino Bonuses 

A live casino bonus lets you play certain live dealer games on a live casino site. This bonus gives you free play chips for live casino games like blackjack, roulette, and poker. Unlike regular online casino bonuses, live casino bonuses have a high wagering contribution rate (10% vs even 100%). Like table games bonuses, these can reach thousands of dollars in value, making them more fitted for high-rollers.

• Wagering requirements
