Guide to the Best Casino Deposit Bonuses

Let's start with a question: What are the criteria when you choose an online casino? Variety of games? Great customer service? Various forms of payment? Countless things are worth discussing when it comes to online casinos; however, they all have one thing in common: they all serve the interests of the players. Thus, in our opinion, the best casino should be the one with the most player’s benefits, or in other words, the best casino bonuses.

Online casinos have always had an advantage over land-based casinos mainly due to the abundance of casino bonuses. They are usually divided into two main types: no deposit bonuses and deposit bonuses. However, we won't cover the no deposit bonuses here - you can learn about them via the following link. Instead, our purpose is to introduce you to casino deposit bonuses, the crown jewel in any online casino.

So, what matters when choosing an online casino to play? It is the bonuses offered with their terms and conditions. Do you love slot games? Choose for yourself the match deposit bonuses with slot-specific offers. What about Blackjack? Turn your attention to the bonuses for table game players. An excellent online casino should offer a full range of promos for all of its products with the proper terms of service.

In the following sections, we will cover everything you need to know about casino deposit bonuses so that you can pick the best ones for yourself. The first one, is casino bonus terms.

Casino Bonus Terms

Before classifying the online casino deposit bonuses, you should understand a few definitions first. We have gathered some frequently used terms for your convenience:

Wagering Requirements (Playthrough): The amount of deposit and bonus that must be wagered before requesting a withdrawal. The wagering requirements are represented by a number of times, for example, 30x the bonus and deposit amount.

Bonus Codes: Some online casinos may ask for a promotional code when redeeming a specific bonus. Usually, you can enter the code in the Cashier section.

Welcome Bonus: This is a bonus exclusive for new players. It usually includes match deposit bonuses and/or free spins. A typical welcome bonus should have multiple deposit levels with different offers.

Wagering Contribution: The contribution made by different games towards the wagering requirements. For instance, slots have a 100% contribution, meaning that anything wagered on slots will fully contribute to the playthrough. On the other hand, table games such as blackjack tend to have lower rates, at 5 - 25%.

Cashable Bonuses: The bonus and winnings can be withdrawn once the wagering requirements have been fulfilled.

Non-Cashable Bonuses: Only the winnings can be withdrawn once the wagering requirements have been fulfilled.

Maximum Bonus: The maximum amount of bonus offered, for example, a 100% match deposit bonus of up to $100. In this case, you can receive at most $100, and any exceeding amount will not be recognized.

Verification Process: To withdraw the casino deposit bonuses, you must fulfill the security check by turning in the required ID documents and waiting for verification.

These are terms you will often encounter when using any casino bonus. Pretty straightforward, isn’t it?

Types of Best Casino Deposit Bonuses

There are many types of casino deposit bonuses that you can come across. You don't have to use all of them, just use what you need. Online casinos also restrict the use of more than one bonus at a time, and breaking the rules will result in voiding all your progress. So if you had to choose, which bonuses would you redeem?

Welcome Bonus Package

The welcome bonus package is reserved for newly registered players only. This is the most popular casino deposit bonus, and almost all online casinos have at least one variant of the welcome package.

A popular welcome bonus package often includes two different bonuses: the match deposit bonus and the free spins. Match deposit will give players a bonus amount corresponding to the amount they deposited, such as 100%, 200%, etc. Free spins are as the name suggests: you can spin for free on specified slots, for example, 30 FS for Mega Moolah, 20 FS for Book of Dead, and so on. Of course, depending on each casino’s policy, there will be a different combination of those bonuses.

Reload Bonuses

Unlike the welcome bonus package, the reload bonus is for players who have registered at the casino before. You will receive a bonus amount corresponding to the amount you deposit (reload). For example, if you have used up your first bonus, you can make another deposit. The casino will offer you various bonus options for that deposit, such as a match bonus or free spins.

Refer a Friend Bonuses

This is a form of an online casino promotion. Every time you refer a family member or friend to play at their casino, you will receive a lot of exclusive bonuses. These are often referred to as "Refer Friend Bonuses" and come in many forms: Free spins, free cash, or lottery tickets. Sometimes the referral bonus also includes accumulative points, helping you to redeem many attractive gifts when you reach the milestone.

VIP Bonuses

This type of bonus is only available to players who have been recognized for contributing to the casino, or in other words, have VIP status. The more money you deposit, the higher the VIP level you will get. Each VIP level will have its exclusive gifts and promotions, as well as special customer care programs. Some of the benefits include tickets to exclusive casino events, birthday gifts, a dedicated account manager, VIP special offers, etc.


It can be easy to get confused when choosing and claiming the best casino deposit bonuses out there. We hope that our bonus guide has been helpful to you on your journey ahead. Good luck gambling!


Frankly speaking, no. Most casino bonuses have certain restricted games stated in their terms and conditions, including the no deposit ones. This means you can play all of the casino games aside from the restricted ones. In addition, the free spin you get from the casino can usually be applied on selected slot machines or slot machines with free spin bonuses.

Wagering requirements are a vital component of all rewards in online casinos. You can't just get a bonus, and withdraw your money immediately.

You will need to play with your bonus money before being allowed to make a withdrawal.

Wagering criteria specify how many times you need to play for a withdrawal with your bonus money to "unlock" them. For instance, if you get a $10 bonus with 40x wagering requirements, it means that before making a withdrawal you need to place bets with a total value of $400.

Our advice to you is you do not need to always get the bonus. Because casino bonuses always come with a certain requirement which is the wagering requirement. Before getting a casino bonus, you should read the term and conditions carefully or reach customer support to get bits of help. 

After all, things are clear, you can decide to claim deposit bonus or not. 

Like other casino games, video poker also has its own deposit bonuses. They can be divided into cashable bonuses and non-cashable bonuses. However, whichever one you choose, you should read the terms and conditions carefully before using them.

Depending on the casino's policies, the casino deposit bonus can be withdrawn or not. However, the process is simple in most cases - all you need is fulfilling the requirements, completing the verification process, and that's it.
