Casino Bonus Offers: What Types Are There?

If you’re not sure how an online casino bonus works, we’re going to break it down to the basic details.

You’ll find various kinds of offers when you sign up to a gambling site – some are limited to new players, others are given out to loyal players. Each of these casino bonuses works differently. Let’s take a look at the inner workings of the most common types.

No deposit bonus

A no deposit casino bonus is the best kind of offer, especially if you’re not an experienced player. It does exactly what it promises, giving you free cash or free spins without the need to make a deposit.

Remember that if you want to cash out any winnings from this free casino bonus you’ll still need to fulfill playthrough and make an actual deposit. These bonuses are typically small, for obvious reasons. Expect anything between 1 and 10 free spins or $1 to $2 added for free to your account.

Expert Tip: Even when using a no deposit casino bonus you need to check the wagering requirements to see if you can afford playthrough.

Welcome bonus

A casino welcome bonus adds something extra to your first deposit, such as free spins, a match deposit where you get bonus cash added to your account, or a mix of both.

Casino welcome bonuses vary wildly and can be anything between $500 and $3,000 in bonus cash or between 10 and 250 free spins. The most generous casino sites can exceed these averages.

Sign-up offers are always worth taking up because you can check out a new casino and figure out whether you like it without using up too much of your money. Always take note of wagering requirements – the gold standard is 35x, but it’s reasonable to expect up to 50x if the casino bonus is large.

Expert Tip: Make sure that the minimum deposit required is reasonable. Most casinos ask for $10 to $20.

Free spins

A free spins casino bonus gives you a number of rounds to use on a specific game or selection of games. Check the terms to see which slots are eligible as these are usually given out on new slots or on old classics like NetEnt’s Starburst.

Some casinos offer them as part of a sign up package, but returning players will also find weekly free spins bonus casino offers too. Expect to see between 60 spins, like at Bspin casino, or even 300, like StayCasino’s new player offer.

Expert Tip: I usually look for a free spins online casino bonus with an expiry period that’s longer than 24 hours.

Casino deposit bonus

A casino deposit bonus can take two forms:

• Match deposit bonus for new players where your first deposit matched up to a certain amount. For example, Bovada offers 100% up to $3,000 so if you deposit $10 you’ll find $20 added to your account.
• Reload casino bonus for returning players – Works exactly in the same way, but valid for subsequent deposits. Super Slots Casino currently has a monthly reload of 100% up to $300.

Expert Tip: Try to find deposit bonuses that give you at least 7 days to fulfill playthrough so you can enjoy the experience without being rushed.

Online casino bonus codes

Some sites ask you to key in an online casino bonus code so that you opt into the offer. We will always display these codes prominently so you don’t need to worry about looking for them. The casino also usually lists these clearly in the bonus terms and conditions.

Casino bonus codes are keyed in towards the end of the registration process for sign-up offers. In case of a reload, make sure you type in the code in the correct field when you’re making your next deposit.

Expert Tip: I once forgot to key in the promo code and messaged customer support. They sorted it out for me, so don’t panic if the same happens to you.

Casino cashback bonus

Cashback casino bonuses literally give you back a percentage of your losses within a time period. These are typically offered to regular players as a thank you and can range between 5% and 20%.

The amount usually depends on how much money you’ve wagered or which level of the loyalty program you’ve reached. DuckyLuck’s daily cashback, for instance, depends on how much money you deposited the previous day.

Expert Tip: Online casinos that offer a daily or weekly cashback bonus are better than those with just a welcome package as you’ll always have some of your losses covered.

High roller casino bonus

Strictly for the long term players who know how to strategize risk, this is offered if you deposit above a certain amount, usually $500. A high roller casino bonus can be a match deposit of 250% up to $5,000 or a cashback as high as 35%.

Expert Tip: Since a high roller offer is so expensive I give myself a few hours to reflect before committing.

Other types of casino bonuses

Online casino bonuses aren’t limited to the above. Here are some of the most common other types of promotions you’ll encounter.

• Loyalty program – A range of rewards from cashbacks to higher deposit and withdrawal limits. The higher you go in the program, the bigger the offers.
• Exclusive player bonuses – A customized casino bonus that is tailored to your gambling style and budget.
• Refer-a-friend bonus – Get a friend to join using the code given to you by the casino and you’ll receive a reward, such as free bonus cash.
• Sports betting bonuses – These can be free bets, risk free bets or deposit matches to use on your favorite sports.
• Seasonal casino bonuses – Special times of year like Christmas, Summer, Valentine’s Day and other holidays come with specific bonuses.
• Birthday bonuses – Check your account for a reward on your special day. You will usually receive an email to alert you.

Finding the Best Casino Bonuses: Expert Tips

So you’re hunting for the best online casino bonus? Check out our expert tips to make sure you only subscribe to the best promotions.

#1 Pay attention to the bonus amount ✅

The bigger the bonus, the better. However, there are exceptions. If you’re putting in a $10 first deposit, a 100% match up to $200 is just as good as a bonus of $1,500 as you’ll be getting your money doubled either way. Pick the one with lower wagering.

#2 Compare bonus offers at different casinos ✅

The nature and amounts of casino bonuses can vary significantly. Consider that Rocketplay offers a welcome casino bonus of $600 + $100 free spins, while Jackpot City offers up to $1,600 in bonus cash. Do your homework to understand which works better for you.

Did you know? A larger free spins offer is not always the best offer, especially if you’re not interested in the eligible games.

#3 Look for casinos with 2 or more bonuses ✅

Two casino bonuses are better than one. Accurate, right? The more promotions offered by a site, the stronger the indication that you’ll enjoy a good experience there.

#4 Read the Terms and Conditions carefully ✅

We can’t repeat this often enough. Always check the casino bonus terms and conditions (T&Cs) to avoid nasty surprises. According to Research Gate, wagering requirements and the expiry term are the most important terms to take note of. We’ll be going in more detail further down, and we always reproduce the most important terms clearly for you so that there’s no confusion.

#5 Choose a bonus that matches your bankroll ✅

If you’re a casual player with a low bankroll, don’t stretch yourself too far by aiming for a highroller casino bonus. If you planned to make a $20 deposit but the bonus asks for $50, move on to the next one.

#6 Look for bonuses with low wagering requirements ✅

If you can only afford 35x requirements, ignore bonuses with 50x no matter how generous. If you don’t fulfill playthrough you won’t be able to cash out your winnings.

How to Claim a Casino Bonus

Your first time claiming a casino bonus? No stress. Here’s a step-by-step guide to everything you need to take into account as a first-time player.

Important Casino Bonus Terms

From the information already given here you probably have a good idea why casino bonus T&Cs are so important. Let’s delve deeper into what to watch out for.

Minimum deposit

Every offer has a minimum deposit requirement attached to it, unless it’s a no deposit bonus online casino offer. Some low deposit sites like JVSpin Casino accept as little as $1, but the vast majority require at least $10.

Minimum and maximum betting limits

When using bonus money you won’t be able to bet as much as you like. Whether you’re using free spins or bonus cash, you’ll have a limit of $0.10 to $0.50 per spin. The casino does this to make sure that casino bonuses don’t become too expensive.

Bonus expiry time

You will have a limited time period to claim and use your online casino bonus. The first expiry time to take note of is the time you have between completing your registration and making your first deposit. This can be between 24 hours to 3 days, as is the case at Rolling Slots Casino.

Next, check how long you have to fulfill playthrough. Once again, this can vary between 3 and 30 days, although the industry average is 7. Rolling Slots gives a reasonable 7 day window to meet wagering requirements of 35x.

Wagering requirements

These tell you how many times you must wager the bonus before cashing out the winnings. They can apply to bonus cash only, or even to your deposit.

Maximum win limit

An online casino bonus also carries a maximum win limit, so as to reduce the risk of the casino having to dish out enormous sums of money in winnings that it can’t afford. The maximum depends on the size of the bonus being offered and how much you deposited.

How We Rate the Best Casino Bonuses

📌 Reputation of the casino offering the bonus

We also take a good look at what other players are saying about the casino. We check social media platforms and players’ forums like Reddit for a vibe check. If there are too many repeat complaints this sets our alarm bells going.

Casino Bonus Payment Methods

Every offer requires a deposit, unless you’ve picked a no deposit bonus casino site. Choosing the most convenient payment method for you is important, so here are some considerations to help you make up your mind.

• Bank Cards – Credit and debit cards like Visa and MasterCard are very commonly accepted. They’re great for higher transaction limits, but tend to take longer for withdrawals.
• eWallets – Digital wallets like PayPal or Skrill offer instant deposits and very fast cashouts. The added bonus is you don’t need to share banking details.
• Prepaid Cards: Cards like Paysafecard let you deposit funds without linking a bank account. The downside is you won’t be able to cash out.
• Cryptocurrency: Increasingly popular for their high level of security and anonymity. Withdrawals are instant in most cases.

Expert Tips: Some e-wallets like Skrill and Neteller can be excluded from eligibility, so check the terms carefully before choosing your payment method.

What Games Can You Play with Casino Bonuses?

The vast majority of online casino bonuses are available only on slot games, but check the terms for a list of excluded slots. Jackpots and some other high payout titles are commonly not eligible.

Video slots mostly contribute 100% towards wagering requirements, while table games and live dealer tables may contribute less, or nothing at all. Vinyl Casino is a case in point: table games and video poker, only contribute 10%.

Expert Tip: Don’t waste your bonus cash playing games with a low weighting. Look for sites that offer specific blackjack, roulette or poker bonuses and tournaments.

How to Calculate Wagering Requirements

What does it take to turn your casino bonus into real money and cash out your winnings? It’s mostly a matter of meeting wagering requirements within the stipulated time limit. Sometimes you’ll find this referred to as ‘fulfilling playthrough’ in the T&Cs.

Working out how much you need to spend to cash out is simple. First, check whether the wagering requirements apply only to the bonus cash, or both to bonus and deposit. Next, follow this formula.

Wagering Requirement = Bonus Amount × Wagering Multiplier.

Should You Use a Casino Bonus? Pros & Cons

Is using an online casino bonus worth it? Yes. At worst, you get to enjoy playing real money games without spending more of your cash. At best, you’ll walk away with a profit. Here are the pros and cons to consider.

Use Your Casino Bonus Responsibly

Gambling is meant to be fun, so make sure to keep it that way. No matter how enticing a casino bonus appears, it’s not worth ruining your finances and your mental health over.

If you’re finding it difficult to stay in control, step away and seek help. There are plenty of responsible gambling organizations happy to offer their support for free:

• National Council on Problem Gambling (NCPG) – ncpgambling.org
• Gamblers Anonymous – gamblersanonymous.org
• ConnexOntario (Ontario) – connexontario.ca
• Center for Addiction and Mental Health (CAMH) – camh.ca

It’s also good to prevent the problem before it actually becomes one. Our recommended sites offer excellent responsible gambling tools to help you stay in control. These include:

• Deposit limits.
• Self-exclusion tools.
• Reality checks.
• Cooling-off periods and temporary breaks.
