Types of Casino Bonuses

As discussed, casino bonuses and promotions can significantly enhance your gaming experience and potentially boost your winnings. 

Here, we’ll discuss the various types of casino bonuses that can come your way, as well as some of the basic terminology that you are likely to encounter. Understanding this will help you be well-prepared to navigate the thrilling world of online gambling. Keep in mind that some of the bonuses listed below will be deposit bonuses, which means they require you to make a deposit, and others will be no deposit bonuses, which means that you get them whether you make a deposit or not. 

Welcome bonuses

Welcome bonuses are a staple feature of most online casinos. Since the field is very competitive and increasingly crowded, casinos are resorting to attractive promotions to entice users to join their platforms. These bonuses often come in the form of a deposit match, which means that the casino “matches” a percentage of your initial deposit as a first deposit bonus. When this happens, your starting bankroll is essentially doubled. Also, especially since the emergence of social casinos in the United States, welcome bonuses can come in the form of gold coins, sweeps coins, or the equivalent of any of these. Pay special attention to whether the bonus you are trying to redeem requires a bonus code or not. 

Monthly bonuses

It is one thing to attract players, and a different one to get them to stay. Online casinos know that if they don’t offer bonuses on an ongoing basis to reward their existing players, they will possibly leave and start playing at other online casinos. As a result, many casinos offer monthly bonuses. These recurring promotions can include a deposit bonus when you reload, free spins, or other attractive perks. Monthly bonuses are a critical element of a casino’s retention strategy, ensuring that players feel seen, valued, and acknowledged. 

Free Spins

If you’re a fan of slot machines, then free spins are the equivalent of your golden ticket. Whether you want to cash it out by playing your favorite slots or trying new ones, free spins bonuses open up the door for potential big wins, and at the very least, extended playtime. Online casinos often give out free spins as part of their welcome package, but they can also come as standalone promotions or as added bonuses whenever you make a purchase. When taking advantage of a free spins bonus, some terms you will come across are “playthrough requirements” and “wagering requirements.” We will discuss both later in the article. 

High-roller bonuses

High-roller bonuses are designed for those who like to go big or go home. A high-roller is defined as a player who wagers considerable amounts of money, which often leads to casinos giving them exclusive bonuses and VIP treatment. A high-roller deposit bonus will often be exempt from monetary limits and have better terms regarding playthrough requirements. However, it is important that you remember the golden rule: Never bet more than what you can afford to lose. 

Mobile bonuses

Every day, more people connect to the net via their smartphones instead of through their computers. Online casinos have adapted to this trend by granting mobile bonuses to those who prefer to play on their smartphones or tablets. A mobile bonus code can include free spins, a deposit match, exclusive profit boosts, or a combination of all of the above. The common thread is that this bonus code is only accessible through the casino’s mobile app.

Online Gambling: How Do Wagering Requirements Work? 

As we mentioned, a common term that you will cross paths with when navigating the world of online casinos is “wagering requirements,” which can also be referred to as playthrough requirements or rollover requirements. 

These requirements are set in place by casinos as a protective measure, in order to ensure that you simply don’t cash out your bonus funds immediately after keying in your bonus code. A wagering requirement, in a nutshell, stipulates the amount that you must wager before you can cash out any winnings derived from the bonus you received. 

For instance, if a bonus code has a $100 bonus with a 20x wagering requirement, it means that you need to wager $2,000 (20 times the bonus amount) before being able to make a withdrawal. Wagering requirements vary across casinos, but they are generally between 20x and 50x. 

Also, another important factor is that each type of game contributes differently to these wagering requirements. For example, real money wagered on slot games contributes 100%, while table games like blackjack or roulette generally contribute a lot less or are excluded altogether. 

Once you’ve fulfilled the wagering requirements, in most cases, any remaining bonus funds and the winnings generated from them become eligible for withdrawal. Some casinos will only let you withdraw the winnings–not the original bonus funds–so make sure you check the terms and conditions before signing up.

Steps for Redeeming Casino Bonus Offers

Now that you’ve grasped the concept of wagering requirements, you can look at online casino bonuses and promotions through a better lens. Let’s now walk through the step-by-step process of redeeming the best casino bonuses. As always, remember to visit Lines.com and go to our casino hub to check out how these bonuses work. 

• Choose Your Favorite Casino: First, you need to settle on where you’re going to sign up. Remember to look for casinos that have a solid track record and positive casino reviews, as well as attractive bonuses. Double-check that the casino you chose is eligible to operate in your jurisdiction. Lines.com helps you with all of the above.
• Create Your Account: As you go through the sign-up process, be prepared to provide accurate personal information, and potentially an ID to verify your details.
• Enter the Bonus Code: When you are in the account creation process, you will be prompted to key in the bonus code. Some online casinos do not have a bonus code, and will redeem your bonus automatically.
• Read the Terms and Conditions: Due diligence never hurts. Before claiming a bonus, thoroughly review the terms and conditions associated with it. It will save you from potential disappointment.
• Make a Deposit: While some bonuses are “no-deposit” bonuses, others require an initial deposit. Once your account has been verified, you will be prompted to make a deposit using your preferred payment method.

After going through this process, you should be able to see the bonus in your account, so you’re all set and ready to start playing!

Calculating the Real-Money Value of Casino Bonuses

We’ve discussed how even the most attractive of casino bonuses will have playthrough requirements that need to be met. Knowing these numbers is important toward calculating the effective value of your casino bonus. 

• Learn About Game Contribution: As we stated, not every game in a casino counts the same when it comes to bonus requirements. Some games, like slots, contribute 100%, while others, like blackjack, might only count as 10%. Every casino is different, so double-check these details with your casino of choice.
• Know the House Edge: The house edge is how much the casino expects to make from a game over a period of time. For some slot games, this number can be as low as 1%, while for others, it can be over 50%.
• Calculate Your Expected Loss: Imagine you’re playing a game, and you bet $1,000, and the house edge is 1%. You can expect to lose $10 because of the house edge.
• Consider the Bonus: Let’s say you find a 100% deposit bonus, which means that if you deposit $100, you get an extra $100 in bonus money. But this bonus comes with a wagering requirement of 20 times the bonus amount. This means that you need to wager a total of $2,000 to fulfill the requirements.
• Consider Your Potential Loss vs. Profit: To calculate the return to player (RTP) you need to consider the house edge. For example, if the house edge is 3%, the RTP is 97%. That means that if you wager $2,000, you will lose $60 because of the house edge. Therefore, if your bonus is, let’s say, $200, your real bonus is $140 because you lost $60 to the house edge in the process.

To put it simply, for a bonus to be worth it, the potential profit needs to be higher than your expected loss. By looking at this simple equation, you can decide which casino bonuses are a good deal, and which ones you’re better off skipping.

U.S. Online Casino Bonus Terms and Conditions

You’ve looked at some of the best online casino bonuses available in the United States. 

Here at Lines, as your trusted partner in navigating successfully through the world of casino bonuses, we cannot emphasize this enough. Before redeeming a bonus, look at the terms and conditions. 

While some promotions might look very flashy on the surface, not all that shines is gold, and by not reviewing the terms and conditions, you might be missing out on promotions that are actually great for you. 

Here’s why paying attention to these terms is key:

• Wagering Requirements: As we discussed, most bonuses will have a wagering requirement. Make sure you know how much it is and that you’re able to complete it, otherwise, you won’t be able to withdraw your winnings.
• Expiration Dates: Many bonuses have an expiration date. This means that if you don’t use the bonus within the specified timeframe, it will expire, and you won’t be able to take advantage of it.
• Game Limits and Contributions: Some bonuses might only apply to certain games. Also, when it comes to wagering requirements, each game will contribute differently to the rollover tally.

By keeping in mind these valuable lessons, you’re making strides on your journey as a successful casino player.
