Are traditional casino bonuses over?  

Across Europe, regulators are coming for casino bonuses.

Sweden has restricted welcome bonuses to a single offer capped at SEK 100. Finland's forthcoming market liberalization will ban welcome bonuses entirely, permitting only certain retention offers for existing customers.

The UK's Gambling Commission spent years deliberating over wagering requirement caps, at various points considering limits so restrictive that industry analysts warned they would fundamentally alter the economics of licensed online gambling. Other jurisdictions may be watching these experiments and drawing their own conclusions.

Studious as regulators have been, they have not been willing to expend political capital and state the truth plainly: the black market is growing, and part of this has to do with the regulated market not being able to advertise its products and services to consumers so that it can prevent the syphoning off to offshore operators.

The implicit logic behind all of this is consistent: bonuses attract players, and attracting players to gambling is something regulators increasingly view with suspicion, fearing public backlash over doing too little. If bonuses bring people in, restricting bonuses will keep people out, and hopefully keep vulnerable people out.

This logic is flawed, and Sweden is a good example of why.

The Swedish experience with restricting bonuses in the regulated market

Sweden's 2019 gambling reform was among the most comprehensive in European history. One of its central features was a strict limitation on casino bonuses — operators could offer a single welcome bonus, capped at SEK 100, with no stacking, no reload offers, and no additional free spins beyond those included in that package.

The intention was harm reduction. The outcome was channelization failure.

By 2024, Sweden's channelization rate — the proportion of gambling activity occurring within the licensed, regulated market — had fallen to 85% overall, with the online casino segment performing worse, at between 72% and 82%. When Swedish gamblers were asked why they were playing on unlicensed sites, 21% cited better bonuses as a primary reason.

At this point, it is worth mentioning that Sweden had a clean slate. It could choose from any regulatory framework at the time, and adapt it to the needs of its consumers to see what would work best. Instead of allowing comparable bonus systems, though, the country embarked on a framework that I hope will serve as definitive proof that bonus restrictions are not necessarily a way to drive players to safe and responsible gambling practices.

Think about the customers. They do not understand the dialogue about regulated and unregulated. What is more, people do not actively think about themselves as "at-risk" or "problem" gamblers, and they do not understand the value of the regulated market until after they have a bad experience with an offshore operator.

They are only interested in getting the better bargain, which, from the standpoint of anything between 18% to 28% of casino players, is simply not offered by the regulated market.

The reason I bring up the "clean slate" argument is that Sweden has been tough on regulated bonus offers from the very start, whereas countries such as the United Kingdom have a better channelization, at around 87.5%. Part of this has to do with the fact that bonuses are competitive, but they are undergoing some serious challenges right now. Lowered wagering requirements and a new taxation regime could see channelization in the United Kingdom slip further.

Gustaf Hoffstedt, Secretary General of the Swedish Trade Association for Online Gambling, has insisted that bonusing needs to change for Sweden to see stronger channelization rates: without revising the bonus restrictions, channelization rates would continue to disappoint. The regulator had made the licensed product less attractive than the unlicensed alternative — and players had responded rationally.

This is the fundamental flaw in bonus restriction as a harm reduction strategy. It assumes that players who cannot find attractive bonuses on licensed sites will simply gamble less. In practice, a significant proportion of them find attractive bonuses on unlicensed sites and gamble there instead — outside the reach of any responsible gambling framework, any complaint mechanism, any consumer protection whatsoever.

The real problem: Players don’t know what they are getting

The case against casino bonuses, as regulators frame it, is that they are used to attract players who might not otherwise gamble. This is true. It is also largely beside the point.

The actual source of most bonus-related harm, and the source of the vast majority of bonus complaints that Casino Guru receives and mediates, is not that bonuses exist. It is that players do not understand how they work.

To the regulators’ credit, this has been actively addressed in certain places. The UK Gambling Commission requires terms and conditions to be clearly displayed in gambling operators’ promotional materials, and any follow-up to the full terms and conditions needs to be a single click away, or the licensee faces compliance reviews and potential fines. But this belies the real problem.

The real problem is that players do not fully grasp what they get and why one offer may be better than another. They make decisions based solely on intuition, which is precisely what offshore market operators rely on to push their own offers.

Consider the basic comparison a player faces. An unlicensed casino offers 300 free spins. A UK-licensed casino offers 20 free spins. From the player's perspective, one of these numbers is dramatically larger than the other. The licensed casino appears to be offering a fraction of what the unlicensed one provides.

What the player does not fully understand is that the 300 spins may be on games worth a fraction of a penny per spin, with a 40x wagering requirement and a £20 maximum withdrawal. This is an extreme case, I know, but these offers are hardly ever created to benefit you.

The 20 spins may be on a £0.20 per spin game, with a 10x wagering requirement and no withdrawal cap. In monetary terms, the 20-spin offer from the licensed casino may be worth more —possibly significantly more — than the 300-spin offer from its unlicensed competitor.

But this calculation is invisible to the player at the point of decision. They see 300 versus 20 and make the obvious choice. Now, this is not to say that bonuses have been going great in the regulated market in the United Kingdom, or Sweden, for that matter.

Bonus mechanics and the paradox the regulated market faces

Beyond simple quantity comparisons, casino bonus mechanics contain several specific features that consistently generate player harm and complaints, not because they are inherently dishonest, but because they are poorly understood.

The win cap problem: Most bonus offers include a maximum withdrawal limit — the most a player can extract from winnings generated by the bonus. This cap may be €20,€50, or €100, regardless of how much the player actually wins during the bonus play.

The problem is not the cap itself. The problem is its visibility. A bonus advertised as "300 free spins" in large text, with "maximum withdrawal £20" in the terms and conditions, is not technically deceptive, but it is designed to be noticed first for the number that sounds impressive and understood later for the constraint that matters most.

This is why the United Kingdom, as I have repeatedly cited as an example, has been hounding operators and holding them to a very strict compliance standard whereby they need to fully comply with bonus transparency rules.

Paradoxically, this added some blandness to the promotional offers available in the regulated market, although the real hit has come after the reduction of wagering requirements, and now, the new tax regime will further suppress the market’s ability to offer competitive promotions.

Back to the purely mechanical side, and the lack of actual plain understanding of bonus mechanics (not through any fault of their own, but because of how some bonuses are explained to them), we end up with a situation where players are reaching out, seeking our help.

In the complaints we handle at Casino Guru, a recurring pattern involves players who win significant amounts during bonus play, continue wagering to meet the requirement, and discover at the point of withdrawal that a cap they had not noticed limits their winnings to a small fraction of what they had accumulated. The wagering was real. The win was real. The cap was in the terms. The player feels cheated — not without reason.

The wagering calculation trap: Wagering requirements are expressed as multiples: 10x, 20x, 35x. What players frequently do not understand is what is being multiplied.

In some casinos, the wagering requirement applies only to the bonus amount. In others, it applies to the deposit plus the bonus combined. A 10x wagering requirement on a €100 bonus sounds manageable — €1,000 in total wagers. A 10x wagering requirement on a €100 deposit plus a €100 bonus is €2,000 in total wagers. The multiplier is the same; the actual requirement is double.

This distinction is rarely explained at the point of bonus acceptance. It appears in the terms, typically expressed in language that requires careful reading to parse. Players who do not read carefully — which is most players — discover the difference when they try to withdraw.

The timing of the cap: There are two logically coherent moments at which a bonus cap might apply: when the wagering requirement is completed, or when the player makes a withdrawal request. Many players assume the former — that once they have met the wagering requirement, whatever balance they have is theirs to withdraw.

This, however, does not exhaust the problems players run into. Another persistent issue is the so-called double cap of bonuses, and specifically the winnings thereof.

Let’s say you have received a bonus and have earned the maximum, say $50 in winnings. You may have earned more, $100, for example, but your winnings would still only be $50.

The issue arises if you do not immediately withdraw this money but continue playing with it. From the point of view of the player, they have cleared the conditions and should have forgotten about the bonus. From the casino’s perspective, by not withdrawing the money, you are still playing the bonus.

This creates a catch-22 situation. Any winnings after the $50 you have won under the bonus are still capped at $50. In other words, before you withdraw the $50, you cannot win anything above it, and just like you suspect, you only stand to lose.

It seems like a minor technicality, but players discover, once again, how serious its implications can be.

In practice, a significant number of casinos apply a cap on withdrawals. This means a player can complete the entire wagering requirement, accumulate a balance that appears to be fully earned, and then discover at the withdrawal stage that their winnings are subject to a cap they had not factored into their play. From the player's perspective, this feels like the casino has changed the rules after the fact. From the casino's perspective, the rules were always in the terms. Both perspectives are simultaneously true and unsatisfying.

To make an actual change, we need transparency, not restrictions

I am not a big fan of the way our industry phrases the debate - we often insist that the gambling industry is generating a substantial tax revenue to governments, that the people employed in the sectors often run in the tens of thousands, or that only a "small number" of people are experiencing a gambling problem.

We often, it seems, resort to fear-mongering to try and address structural issues that need a more reflective and targeted approach - creating an industry that educates gamblers about what bonuses are, how they work, and why they are offered. This last one - the "why" is an essential part of it all.

At the same time, the regulatory response to all of this has been to restrict bonus structures, cap wagering requirements, limit the number of offers, and ban certain bonus types entirely. The Swedish experience, contrasting it with the channelization rates of the UK, suggests this approach is counterproductive.

The more effective intervention is not to change what bonuses casinos can offer. It is to change what information players must be shown about those bonuses.

Specifically, at the point of accepting any bonus, players should be shown the crucial information about the bonus, which should include the sum that they need to wager, the approximate monetary value (in the case of spins or cashbacks, and other applicable promotions)of the bonus if we are talking about free spins, and most importantly, how much they can win or withdraw from such a bonus. Critically, players need to be taught how to calculate this value by themselves, and this starts by having the real value displayed within the regulated space.

This single change would transform the comparison a player makes between a licensed and an unlicensed casino. The unlicensed offer of 300 free spins at 40x wagering becomes comparable to the licensed offer of 20 free spins at 10x wagering — because both are now expressed in the same units. Players who currently choose the unlicensed option because 300 is bigger than 20 would be able to see that the licensed option may actually be worth more.

Critically, this approach does not restrict what bonuses casinos can offer. A casino that wants to offer 300 free spins can still do so. A casino that prefers no-wagering bonuses can offer those. A casino that has developed a sticky bonus structure — where the bonus balance is non-withdrawable but extends play time significantly — can offer that. The variety of bonus structures is preserved; the information available to players is dramatically improved.

In essence, good casinos should strive to educate their players on how bonuses work and teach them how to calculate this basic information for themselves. By doing so, players will become empowered and knowledgeable and not be so easily swayed by black market bonus offers.

But the regulated market can scarcely afford to do so right now, as strict compliance guidelines are to be followed. Therefore, the change should come from the watchdogs, possibly lawmakers, but doing so right now would go against what the current regulatory framework posits - not just in the United Kingdom, but also in markets such as Sweden and Germany.

Admitting that these measures were most likely wrong and that they have had the opposite of their intended effect also comes at a steep price; although some jurisdictions have led the way. Sweden and the Netherlands are good examples of regulators admitting mea culpa and keeping the numbers in the open.

Germany has been reluctant to acknowledge that its purported channelization rates are nowhere in the same territory as independent audits. The Netherlands acknowledged that perhaps 50% of its market is based on offshore operations.

All of this feels primordial in a sense - it hardly means an imminent change in the way bonuses work is pending, but there have been jurisdictions that are willing to acknowledge the possibility of mistakes in the way they do things, which is what brings us closer to a refined framework.

The Win Cap must be front and center

Alongside monetary value disclosure, the maximum withdrawal limit or the win cap needs to be elevated from terms and conditions to a prominent display.

A bonus with a €20 maximum withdrawal is a fundamentally different product from a bonus with no maximum withdrawal, regardless of how many spins or what wagering requirement it carries. This is the single most important piece of information a player needs to evaluate a bonus offer, and it is currently among the least visible.

The fix is straightforward: the win cap should be displayed as prominently as the number of spins or the bonus percentage. Not in a footnote. Not in terms that require clicking through. In the headline offer. "300 free spins: maximum withdrawal €20" is a different headline from "300 free spins," and it is the accurate one.

Combined with monetary value disclosure and wagering requirements, this would give players the two pieces of information that matter most: what the bonus is worth in expected value terms, and what the maximum they can ever extract from it is. Everything else is merely detail.

However, this does not specifically address the core issue, which is the fact that offshore casinos and black market operators would not simply change the way they advertise their offers. This can be seen as a short-term challenge, but the long-term implications of a more competitive bonus scene in the regulated market would, in all likelihood, result in more players sticking around.

Let’s think about it logically. Most players are disappointed with offshore casinos the instant they win big and find out that they cannot cash out their money, with no one to police these withdrawals. At this point, they have discovered that the casino - no matter how it advertises its bonuses - is probably not worth their time and effort, let alone finances.

By offering regulated operators the breadth to push more competitive markets, predicated on transparency, brands can build consumer trust and eliminate the factors that drive people offshore. True, advertising a max win of GBP or EUR 20 is a hard sell, versus the 300 free spins, but over time, and through education, consumers may see that the regulated market is looking out for their best interest.

Transparency in bonus offers is non-negotiable and ought to happen. But for the end-user to truly thrive, I still believe restricting bonuses and raising taxes on the sector is a counterintuitive way to do it. Remember, it’s not about regulated versus unregulated, it’s about perception.

Which casino is offering me – the unsuspecting consumer – the better bargain?

Variety Is a feature, not a problem

One objection to bonus regulation that is worth making explicitly: the diversity of bonus structures currently available is not, in itself, a problem.

Different players have different preferences. Some want large, high-variance bonuses with the possibility of a significant win. Some want small, low-wagering offers that extend play time without much risk. Some — like the American casino visitors who favor sticky bonuses, which provide a large nominal balance that cannot be withdrawn but dramatically extends the session — want the experience of playing with a large sum regardless of the withdrawal implications.

These preferences are legitimate, and the variety of structures that have evolved to serve them reflects genuine market responsiveness to player demand. Standardizing bonus structures — forcing all bonuses into a single format, as some regulatory proposals have suggested — would eliminate variety without addressing the underlying information problem. Players would still not know the crucial information about the bonus and bonus mechanics. They would just have fewer options.

Operators also have a part to play. Legitimate operators, and those that want to establish a better industry, that benefits their own business operations, should put education of players as a key point of their business strategies. Educated players find it easier to resist black market offers, as they realize that the displayed value is "for show" while having disadvantageous implied terms and conditions.

The goal should be a market where players can choose freely among varied bonus structures because they understand what each one is actually offering them. Not a market where variety has been eliminated to make the regulator's job easier.

The limits of this solution

One honest acknowledgment is necessary. Monetary transparency requirements imposed on licensed operators will not apply to unlicensed ones. A black market casino offering 300 free spins will not voluntarily disclose that those spins are worth €3 in monetary value. The information asymmetry between licensed and unlicensed operators will persist.

This is a real limitation — but it is not a reason to abandon the transparency approach. A player who understands how to evaluate bonus offers — who has been educated by clear disclosures in the licensed market — is better equipped to assess unlicensed offers skeptically. The casino that claims to offer 300 free spins with no wagering and no win cap is making a claim that an informed player will view with appropriate suspicion.

The licensed market cannot force the unlicensed market to be transparent. It can, by being transparent itself, help develop a player population that knows what transparency looks like and notices when it is absent.

What regulators should actually do?

The case for bonus bans and heavy structural restrictions rests on a harm reduction logic that the evidence does not support. Players want bonuses. When licensed casinos cannot offer competitive ones, players find unlicensed casinos that can. The harm reduction achieved within the licensed sector is offset —possibly more than offset — by the harm generated in the unlicensed sector, where no protections exist at all.

The case for transparency requirements rests on a different logic: that informed players make better decisions, and that the current information environment systematically prevents informed decision-making. This logic is supported both by the evidence on player complaints — the vast majority of which involve some form of misunderstanding about bonus mechanics — and by the basic economics of how bonus offers are currently presented.

Regulators who want to protect players from bonus-related harm should mandate: clear disclosure of bonus information; prominent display of win caps alongside headline offer numbers; plain-language explanation of wagering calculation methods at the point of bonus acceptance; and honest description of when and how caps apply.

They should not mandate: uniform wagering requirements; limits on bonus quantities; bans on specific bonus structures; or any measure that makes licensed casinos less competitive with unlicensed ones without making them safer.

The bonus is not the problem. The information — or the lack of it — is. The implications are shared by players, regulators, and arguably operators themselves, who must start advocating for a more transparent industry if the regulated market is to compete with the goliath that is the black market: inexorable, insatiable, and unrelenting.
