Best Online Casinos in 2024 — Compare and Play at Top Casino Sites

Every time we review an online casino, these are the steps we go through, so you know we leave no stone unturned. In all the reviews that Bookofslots.com carry out, we stick to strict criteria, and we rate all online casinos in the same way. Here’s how our reviewers work around a review of an online casino.

📜 Licensing and Regulation

The starting point for assessing a real online casino is licensing: is it regulated by a reputable online gambling authority, such as the MGA, UKGC or Curacao eGaming? These licensers hold their licensees to the highest standards. If a site doesn’t have a licence, the operator isn’t holding itself to any standards: you run the risk of being treated unjustly, and the casino will have no one to answer to if it cheats you or doctors game results. Make sure you play only at licensed online casinos.

🔒 Responsible Gambling

All top casinos provide responsible gaming tools, which you can use as a player to set deposit, loss, or daily, weekly or monthly wager limits. At any time, you can increase, decrease or stop using them. The site you play at should make it easy to contact any of the local and international gambling support groups like Gambler’s Anonymous or GAM Stop.

👤 User Experience

User Experience refers to how you interact with a website. It covers everything about a website, from loading times to navigation. Consider your initial reaction when you enter a new online casino. We check reviews from existing players to ensure that the online casino offers players a hassle-free experience.

💳 Payments and Withdrawals

A good online casino should provide a wide range of deposit and withdrawal options. At the very least, it should accept debit/credit cards, online banking and as many e-wallets as possible. You should definitely consider opting for a casino that accepts cryptocurrencies, vouchers, and other prepaid options. Make sure to check the casino’s withdrawal processing times. The faster, the better. Bear in mind that your payment method could also influence your withdrawal times.

🎁 Casino Bonuses

Winning games is going to be the best way to make money when playing on casino sites, but you can pick up some extra cash with the help of bonuses and promotions. We pride ourselves on spotlighting platforms that have plenty of offers for users.

🎮 Game Selection

When picking an online casino, the selection of games is going to be a massive factor in your choice. We often consider which platforms have the best selections to cater to users with varying preferences. A good variety of online slots is usually going to be present at most online casinos, as they’re a popular and often low-stakes way to get involved with online casino gaming. Another major category is what is known as “table games,” which include popular card games such as poker, blackjack, and baccarat. Table games also include roll-based casino favourites such as craps and roulette.

📍 Localization

iGaming and gambling localization is the process of adapting casino games and sports betting platforms to the language, culture, and governance structures of a certain jurisdiction in a specific country, territory or language. It can present many opportunities for operators as well as players in the online gambling landscape.

Top casinos offer the same combination of features – things like security, withdrawal speed, customer support and bonuses – that make an online casino a fun, safe and valuable experience for players. The following paragraphs explain what these features are and why they are important.

When it comes to slots, classic games such as Starburst, which have been around for many years, will likely be available, but with newer slots added into the mix, such as video slots, like Nightmare on Elm Street.

Average casinos will have a few hundred games available compared to top casinos that will more than likely have games running into the 1000s.

Video slots and live dealer games are new and trending and usually offered by casinos that have been listed/rated by Bookofslots.com.

There are a plethora of online casino games available, from slots and scratch cards to casino table games, including roulette and poker. In this next section, we will look at the available casino games in more detail.

🎲 Casinos with Online Slots

Online slots, also known as online slot machines, are digital versions of the traditional slot machines found in brick-and-mortar casinos. They are one of the most popular forms of online gambling and are offered by a wide range of online casinos and gaming platforms.

🎲 Casinos with Online Casino Blackjack

Blackjack is known by some as 21. In Blackjack, everyone plays against the dealer. Players receive all cards face up and the dealer’s first card is face up and the second is face down. The object of the game is to get closer to 21 than the dealer without going over 21. If a hand goes over 21, it is called a “bust” or “break”, and the wager is lost. Although blackjack is mostly a game of chance, there are some strategies that will help you to successfully make the most of your bets and payouts.

There are numerous different blackjack games and variations, including Spanish 21 and Blackjack Switch.

🎲 Casinos with Online Roulette

Online roulette is one of the popular games in live casinos. It is a game where a ball spins on a wheel a few times, then it settles down on a spot that has a number. Players place bets on one spot or multiple spots. If the ball stops at the player’s spot, then the house pays the player 35 times the bet or 38 times the bet.

Aside from European and American roulette, there are several other variants of the game, including multiball roulette, multi-wheel roulette, and slingshot roulette.

🎲 Casinos with Online Poker

Poker is a card game where players place bets on their hands (the cards they are dealt), being better than the other players’ hands.

🎲 Casinos with Video Poker

Video poker is a fun and interactive game that combines the best parts of poker and slot machines, and one of the best things about it is that learning how to play takes no time at all.

There are lots of different variants of video poker including Jacks or Better, Deuces Wild and Double Bonus Poker, but they all work pretty much the same way.

Software providers play a crucial role in online casinos as they are responsible for developing, maintaining, and updating the software platform that allows players to access and participate in various casino games. These providers create the foundation for all the games offered on the online casino site, including slots, table games, live dealer games, and more. They ensure that the software is secure and reliable, providing a seamless gaming experience for players.

Casino bonuses and promotions are offered by casinos to entice new players to sign up with them and to reward existing players for their loyalty.

In this next section, we will look at some of the most popular bonuses that casinos offer players.

🎁 Online Casino Sign-Up Bonus

A sign-up bonus is offered to new players who sign up and register with a casino.

Sign-up bonuses can come in all shapes and sizes and could be a deposit match bonus, no deposit bonus or free spin bonus.

A sign-up bonus is a promotion offered by an online casino or sportsbook when you sign up for the first time. It’s a deposit bonus associated with your first deposit. It usually is free money the casino or sportsbook offers to play with to get your business. With a sign-up bonus, you usually get a percentage of what you deposit the first time as a new online casino or sportsbook customer. When you use a sign-up bonus, the online casino or sportsbook matches a pre-agreed percentage of the deposited funds.

In this case, that bonus offer is as follows: 100% up to $500. Minimum deposit $20. Wagering requirements x30. Maximum bonus value $500.

🎁 Online Casino Deposit Bonus

A deposit bonus can be used by players who have already signed up to the casino and is a bonus given when a player makes a deposit.

Popular types of deposit bonuses are the reload bonus for repeated deposits and a deposit bonus divided into bonuses over several deposits.

🎁 Reload Bonus

Reload bonuses are promotional offers that reward gamblers for making more deposits after their first. Compared to sign-up bonuses that are exclusively accessible to new players, reload bonuses are meant to keep existing players playing. Here's how they work, how to claim them, and how to satisfy the wagering requirement.

Example Reload Bonus Bonus Offer:

50% up to $200.
Minimum Deposit - $50.
Wagering Requirements - x25 the bonus amount.

How to Calculate Wagering Requirements:

Determine the Bonus Amount - If you deposit $100, you receive a 50% bonus, which is $50.

Calculate the Total Wagering Requirement:

The wagering requirement is x25 the bonus amount.

Therefore, $50 (bonus) x 25 = $1,250.

This means you need to place bets totaling $1,250 before you can withdraw any winnings from the bonus.

🎁 Online Casino Free Spins

Free spins are given to players to play on slot machines in an online casino, offering the chance to win real money with no deposit necessary. These free spins no deposit promotions provide an excellent opportunity for players to experience the thrill of online slots while potentially earning free spins real money rewards.

Let's take a look at how this bonus works, using the example of a 50 free spins bonus, which requires a minimum deposit of $10 and has x20 wagering requirements. The bonus is for the game Big Bass Splash, with each spin valued at $0.10.

To activate the 50 free spins, make a minimum deposit of $10. Once the deposit is made, the free spins are credited to your account and can be used on Big Bass Splash. Each free spin is worth $0.10.

Any money you win from these free spins is usually considered bonus money and is subject to wagering requirements.

For this bonus, the wagering requirement is 20x. This means you need to wager (bet) the amount you won from the free spins 20 times before you can withdraw it as real money. For example, if you won $5 from the free spins, you must wager $5 x 20 = $100 before you can convert the bonus winnings into real, withdrawable cash.

🎁 Cashback

A cashback bonus is offered to players on a certain percentage of the losses they have accrued over a week/month.

Cashback bonuses can be offered on a daily or weekly basis or could even be offered to players who prefer live casino or casino table games.

A cashback offer, such as the one advertised for receiving 10% cashback up to $200 weekly, provides players with a refund on their losses within a specified period. To qualify for this cashback, players typically need to incur a minimum loss of $50 during the promotional timeframe. Once eligible, players receive 10% of their net losses back, capped at $200.

The cashback amount received is often credited as bonus funds, subject to wagering requirements of x5. This means that before any winnings from the cashback can be withdrawn as real money, players must wager the bonus amount five times. Cashback offers like these provide players with an opportunity to recover a portion of their losses and continue playing with extra funds.

🎁 Loyalty Bonuses

Loyalty bonuses are bonuses given to existing players and can come in many different forms.

The most popular types of loyalty bonuses are free spins, free cash, free items and sometimes even free holidays or cars.

🏆 Online Casino Tournaments

An online casino tournament is when you compete against other players in a slot or casino table game to score the highest number of points to get a place on the leaderboard. Players at the top of the leaderboard can win free spins or free cash.

Online tournaments are great for players who have a competitive nature.

💸 Online Casino Bonus Codes

Online casino bonus codes are a series of letters and/or numbers that a player must enter to receive a bonus.

Bonus codes are sometimes on the site or could be received via text or email. To use a bonus code, go to the deposit screen or promotion screen and follow the instructions provided.

When assessing online casino payment methods, it's crucial to consider several key factors that can significantly impact your gaming experience:

1. Terms and Conditions: Understand the terms associated with each payment method. This includes any restrictions on bonuses or promotions when using specific payment options.
2. Bonus Eligibility: Check if bonuses can be claimed when using the preferred payment method. Some casinos exclude certain methods from bonus offers to mitigate fraud or abuse.
   
3. Fees: Determine if the payment method incurs any fees. These may vary based on the method itself or the casino's policies.
   
4. Withdrawal Speed: Evaluate how quickly withdrawals are processed using each payment method. Methods like e-wallets generally offer faster withdrawal times compared to bank transfers.
   
5. Withdrawal Limits: Know the minimum and maximum withdrawal limits imposed by the casino for each payment method. These limits can affect how much and how frequently you can withdraw your winnings.
   
6. Minimum Deposit: Check the minimum deposit requirement for each payment method. This ensures you can fund your account according to your budget and preferences.
   
7. Maximum Deposit: Similarly, be aware of any maximum deposit limits imposed by the payment method or the casino. This can influence your ability to deposit larger sums if desired.

By carefully considering these factors, players can make informed decisions about which payment methods best suit their needs in terms of convenience, cost-effectiveness, and efficiency when engaging in online casino gaming.

💳 Debit & Credit Card Casinos

Debit and credit card casinos are gaming sites that accept the use of payment cards to make both deposits and withdrawals. For the biggest number of players, who are usually busy and do not have much free time for risking, these online casinos are the best fit, because most of these gambling sites allow customers making deposit and withdrawals instantaneously, which is one of the major advantages of such casinos.

One of the advantages of debit cards is that you can only deposit funds if they are available

The disadvantages are that credit cards usually come with fees, and it is easy to get into debt when you use this method of funding your account..

The most popular card brands are VISA, Mastercard, American Express, Revolut and Chase.

💳 Prepaid Card Casinos

Prepaid card casinos are great for people who prefer prepaid cards. They suit gamblers who want to be in control of their money and only want to spend what they have, or can afford, without borrowing from a credit card company/lender.

Advantages are that you can only spend what you have topped the card up with and a disadvantage is that again, there may be fees involved.

Prepaid Mastercard, Revolut, and Netspend are popular prepaid cards available.

💳 E-wallet Casinos

An e-wallet, short for electronic wallet, for gambling, is a digital payment method that allows online gamblers to store, manage, and transfer funds securely to and from their online casino accounts. Perfect for anyone worried about security.

Some of the advantages of e-wallets are speed, anonymity and security - disadvantages could include fees involved.

The most popular e-wallets are Skrill, CashApp, and AliPay.

💳 Bank Wire Transfer Casinos

Players also often choose to conduct transactions via bank wire transfers because they can directly deposit to or withdraw from an online or mobile casino without the use of a third-party merchant. This greatly reduces the risk of identity theft since your details do not leave the casino.

Security is one advantage of bank wire transfer casinos. One of the disadvantages is long withdrawal times, which can be days instead of hours.

How do I deposit at an online casino?

To deposit using bank transfer at an online casino, follow these steps:

1. Create an Account: Sign up and log in to your online casino account.
2. Navigate to Cashier: Go to the deposit or cashier section of the casino.
   
3. Select Bank Transfer: Choose "Bank Transfer" as your deposit method from the available options.
   
4. Bank Details: Fill in the bank details that the casino provided such as account number and routing details.
   
5. Initiate the Transfer: Through your bank’s online banking portal or mobile app, transfer to the casino’s bank account.
   
6. Make sure that your reference Information is correct: as a client, you are required to insert the reference number (or any other additional information the online casino might ask you for to single out your deposit).
   
7. Confirm Transaction: Verify all transaction details and confirm the transfer from your bank account.
   
8. Wait for Confirmation: Wait for the casino to confirm receipt of your funds, which can take a few business days depending on the banks involved.
   

How do I withdraw at an online casino?

To withdraw money from your casino account using, say, bank transfer, go to your account and find the withdraw option. Choose the amount you would like to withdraw from your account and pick your bank account. Hit confirm and wait for your funds to arrive.

💳 Crypto Casinos

Casinos with cryptocurrencies are ideal for players who prefer to use crypto as a payment method for online transactions.

Crypto casinos come with instant withdrawals, which is a massive

advantage. However, some crypto casinos do not offer other payment methods, and also there could be security issues and a lack of regulation.

Some of the most popular cryptocurrencies are Bitcoin, Litecoin and Ethereum.

💳 Casinos with Pay by Phone

Pay by Phone casinos are great for people who do not have debit cards, credit cards or access to an e-wallet or cryptocurrency.

One disadvantage of Pay by Phone casinos is the fact that players could end up with a huge phone bill at the end of the month; another is not being allowed to use it as a withdrawal method, meaning that players would have to have another withdrawal method in place.

Popular methods for mobile phone payments include EE and O2.

It is important that you are able to recognize a blacklisted casino so you can avoid them. Make sure that you take the following points into consideration when selecting a casino to register with.

❌ Unlicensed Casinos

If a casino has no license from a legitimate body, and inadequate security standards then you should avoid them as they are not a legit online casino.

❌ Recurring Payment Issues

If a casino has few accepted withdrawal methods, high fees and a complicated withdrawal process, then it is wise to avoid them.

❌ Poor Customer Support

Unresponsive customer support and problems addressing player complaints should ring alarm bells - check reviews from other players regarding customer support and if it is bad - avoid them.

❌ False Marketing

Online casinos that offer misleading bonuses and promotions, or have fake testimonials and reviews, or have aggressive pop-ups or spam, and exaggerate the chances of a player winning should be avoided.  

As you can see from the table below, the revenue has grown exponentially across the world since 2017, and there has been significant growth year on year, making it one of the most successful forms of revenue.
