What is a Casino Bonus?

Casino bonuses are promotional offers that provide you with extra cash or free spins to play gambling games. The contents of deposit bonus codes and how you qualify to receive them are entirely dependent on the promotion. Terms and conditions affect how you can use the promotional offer.

Overall, casino bonus codes aim to give you an incentive to sign up to the casino. You should always analyze casino bonuses on offer at a gambling site before signing up. That way, you can see whether a bonus is worth it.

Opinion on casino bonuses is divided. Ar best, free casino bonus codes can add hours to your gameplay. At worst, bonuses are worthless additions to your account. Our final judgment is that most players would be stupid not to take advantage of these deals.

Casino Bonus Codes: Types

As previously mentioned, there are many types of casino bonuses. Some of the most popular include:

Casino Sign Up Bonus

Sign-up bonuses (also known as welcome bonuses) are some of the most famous bonus offers. You receive sign-up bonuses when you create an account and make your first deposit. The biggest welcome bonuses add thousands of dollars to your account. Welcome bonuses are only available to new players.

No Deposit Bonuses

Some players consider no deposit bonuses to be the best promotions at online casinos. Essentially, these free bonuses provide players with a small sum of money for free without making a deposit. Thus, it is possible to win money without having spent anything. However, these bonuses are difficult to find and have strict stipulations attached.

Loyalty Bonuses

Loyalty bonuses are given to you when you are loyal to the casino. This means playing your favorite games and making deposits frequently so that the casino knows you appreciate their services.

Free Spin Bonuses

Free spins bonuses are often attached to welcome bonuses. You get free spins to play on a slot game. Casinos also often use these bonuses to promote new games recently added to their catalog.

Deposit Bonuses

Deposit bonuses award players with bonus cash upon deposit. Casinos match a deposit by a stated percentage. The best offers match deposits by more than 100%.

How Casino Bonus Codes Work

Generally, all casino promotions work in a standard manner. Basically, most bonus codes provide you with a percentage of your deposit in bonus cash. These percentages vary based on the casino. It is usually between 50% and 200%.

Most casinos word their promotional offers in ways such as “200% match sign up bonus” or “get up to *$5000 in bonus cash”. Now, you may be confused as to how this works, but it’s not pretty easy to understand.

Take the first line of the example bonus above; it states that your deposit will be matched 200%. For example, if you decide to deposit $100, you are eligible to receive $200 in bonus cash. We can work this out by multiplying your deposit ($100) by the decimal representing the bonus percentage (in this case, 2.0).

The second example states, “get up to *$5000”. All this really means is that the bonus maxes out at $5000. In this example, to qualify for the maximum amount, you would need to deposit $2500.

It is good to try and take advantage of the big bonuses; however, you will need to deal with the specified wagering requirements if you want to withdraw your winnings.

casino bonus wagering requirements explained

How Wagering Requirements Work

Wagering requirements may seem a little confusing to players who are unfamiliar with casino bonuses; however, they are easy to understand. In a nutshell, these requirements stipulate how much money you need to bet before you can withdraw money won with bonus cash.

Let’s say that you are required to meet a 20x playthrough requirement to withdraw your winnings, and the bonus amount totals to $200. All you need to do is multiply the bonus amount by the wagering requirement to calculate how much you will need to wager.

In this instance, you will need to wager at least $4000 before you can make a withdrawal. We know this because 20 x 200 is equal to 4000.

It is essential to note the wagering requirements attached to a casino bonus as some stipulations remove all value from the bonus. In general, most sites will require you to meet playthrough requirements between 20x and 50x your bonus amount. It is in your best interest to find a casino with the lowest requirements.

While wagering requirements make it harder to win real money prizes with bonuses, these offers are still a worthwhile addition to your bank.

casino bonus terms and conditions

Casino Bonus Terms and Conditions

Often, more terms and conditions are attached to casino bonuses aside from wagering requirements, including:

  • Minimum deposit requirements
  • Time restrictions on bonus funds
  • Casino bonus promo codes
  • Game restrictions

Now, some of these restrictions may scare some players off, but they really shouldn’t. Regarding minimum deposits, you can expect to deposit at least $20 to qualify for a bonus.

In terms of time restrictions, casinos usually require players to play through their bonus funds within a month of receiving it.

Some casinos require you to enter a promo code to activate a bonus. This is not true of all sites, though; some automatically deposit bonus funds into your account after a deposit.

Finally, game restrictions aren’t always applicable, but some casinos limit players from playing games with a more favorable house edge. In the case of free spins, the bonus may be limited to a particular game.

As long as you keep these terms and conditions in mind, you should have no problem claiming bonuses and using them effectively.
