Players know about this situation and do not miss the opportunity to get the best casino bonus and use it in their favor.

Now, let’s understand what bonuses exist and how to use them. Below, our experts have summarized the main details of popular online casino bonuses.

Welcome Bonus

Casino welcome bonus is a special offer to new players when they register at an online casino site and make their first deposit.

The welcome bonus is usually a financial incentive or other offer given to a new player after making his first deposit at the casino site. Commonly, such a bonus is a percentage of the first player’s deposit added to the game account. Also, casino welcome bonus can include additional free spins on popular slot machines.

Welcome bonus gives:
  • A cash reward immediately after registering at the online casino;
  • Start your gaming session with a significant bankroll;
  • The amount of your deposit can be up to 300%.

No Deposit Bonus

No Deposit Bonus is an offer a player can get without depositing to his game account.

Separately, it is worth highlighting a no deposit bonus for registration in the casino. New players receive such a bonus after they register on the gaming platform. A no deposit casino bonus is a small amount of money or a few dozen free spins you can use to play.

The main advantage of using a no deposit bonus is that players do not need to risk their money. It is an excellent opportunity for players to evaluate the quality and functionality of an online casino before deciding to make a deposit.

How to choose the best casino bonus

Choosing the best casino bonus is always individual and depends on your goals.

Below, we will look at five main factors to consider when choosing the best bonus for you. Using these factors, you can choose the most suitable promotion. The best offer is the one that fits your needs and provides the most value to your gaming experience.

Bonus type

The best online casinos offer a variety of bonuses. Above, we’ve detailed what kind of online casino bonuses there are. All you have to do is decide which type of bonus best suits your preferences.

Available games

Check what games you will be able to play using your chosen bonus. Make sure that you will be able to play the games that you are interested in. If the promotion is limited to only certain games, check if you like them.

Size and percentage of the bonus

Pay attention to the size and percentage of the bonus. A larger bonus size may be more attractive, but don’t forget to check the bonus’s terms and conditions. Below, you can read an example of how to calculate casino bonuses.

Bonus validity period

Some bonuses have a limited validity period. So you should check how much time you have. Make sure you will have enough time to use the bonus.

Bonus terms and conditions

Always read the bonus terms and conditions carefully. Pay attention to betting limits, maximum winnings withdrawal amount and other restrictions. All of these can affect your experience with the bonus.


How to calculate casino bonuses

Each bonus has some requirements and conditions. You should remember it if you want to use the full potential of the offer.

The biggest bonus you can get is the welcome bonus. You will find it at any online casino, but only new players receive it on their first deposit.

The welcome bonus is a percentage of their first deposit and allows players to significantly increase their bankroll (have more money to play with), which increases their chances of winning.

Below, we will explain how to utilize the full potential of the welcome bonus.

For clarity, let’s break things down by example.

A casino offers a 200% welcome bonus on your first deposit, with a maximum bonus of €400. The casino asks you to deposit €50 or more to use the bonus.

Let’s consider five options:

  1. Player deposits €40
  2. Player deposits €50
  3. Player deposits €100
  4. Player deposits €200
  5. Player deposits €300

Let’s make a table for each of the five options. In it, we will calculate the size of the bonus, the total amount of money that the player will receive on his account at the online casino, and evaluate how the player took advantage of the potential of the bonus offer:

Player depositBonus amountTotal amount on player’s accountUsing of the bonus
€40 €0 €40 Not used
€50 €100 €150 Minimally 
€100 €200 €300 Normally
€200 €400 €600 Maximally
€300 €400 €700 Partly

Now let’s analyze each option in detail.

  • Option 1: If a player deposits €40, he does not receive this bonus because the minimum deposit amount is €50. The total on the player’s account will be the same as his €40 deposit.
  • Option 2: If a player deposits €50, he receives a bonus of €100 (200% of the deposit). The total amount in the player’s account will be €150 (deposit €50 + bonus €100).
  • Option 3: If a player deposits €100, he receives a bonus of €200 (200% of the deposit). The total amount on the player’s account will be €300 (deposit €100 + bonus €200).
  • Option 4: If a player deposits €200, he receives a bonus of €400 (200% of the deposit). The total amount on the player’s account will be €600 (deposit €200 + bonus €400). In this case, the player uses the maximum potential of the offer.
  • Option 5: If a player deposits €300, he does not receive the expected bonus of €600 (200% of the deposit) because the bonus limit is €400. Therefore, the total amount in the player’s account will be €700 (deposit €300 + maximum bonus €400). In this case, the player does not use the full potential of the offer because of the bonus limit.

From the player’s point of view, the successful options for using the bonus are 2, 3 and 4. Option 2 allows the player to claim the bonus money by making the minimum deposit required to receive it. Options 3 and 4 also give you the bonus. However, it is Option 4 that maximizes your bankroll with minimal effort.

In this example, we have shown how important it is to consider the requirements and limits of bonuses. Always remember it and try to use the offers with maximum benefit.
