The Cobra Effect in gambling regulation: How over-regulation backfires and what regulators and operators can do
The Cobra Effect is when the solution to a problem makes it worse, due to unintended consequences.
The term originates from colonial India, when officials offered a reward for every dead cobra. Enterprising citizens began breeding snakes to collect bounties, and when the scheme was cancelled, they released the cobras, worsening the problem.
In gambling regulation, the same logic applies. Rules designed to protect consumers unintentionally push them to unlicensed sites with fewer safeguards.
Stricter gambling regulations are born from a genuine desire to protect vulnerable players and curb problem gambling. Measures such as stringent affordability checks, stake limits and advertising bans are implemented with the best intentions.
However, when countries impose overly restrictive regulations, legal options become less appealing to some players. These players don’t just stop gambling; they seek out alternatives on the black market.
Creating rules that protect players while keeping the legal market competitive is a balancing act. Some countries, like Denmark, appear to have achieved the balance. Others, like Germany, are learning that excessive regulation can backfire. How can regulators strike the right balance? It is a topic widely discussed within the sector, including at igaming.com.
What the data says about channelisation
Channelisation, the share of play that occurs on licensed sites, remains the clearest test of whether regulation is working. Where frameworks balance access and protection, channelisation is high; where they add friction or narrow product choice, it slips.
Ontario shows what ‘good’ looks like. H2 Gambling Capital has estimated that sports betting channelisation reached 92% in 2024 in Ontario. It is on course to reach 97% by 2028 after opening the market and setting proportionate rules. That contrasts sharply with Canadian provinces that kept monopolies. Their onshore rates hover near 11% and are forecast to stay below 15% by 2028.
Denmark also demonstrates the payoff from steady, open regulation. Channelisation rose to 91.5% in 2024, up from under 40% before liberalisation. GGR grew 5.6% year on year. Online casino was the main source of the revenue, with the sector up 14.7% on 2023.
Germany is the opposite story. The Fourth Interstate Treaty on Gambling introduced a host of restrictions, including a €1 per spin stake limit on online slots, a monthly deposit limit of €1,000 across all providers, and a 5.3% turnover tax on online slots. The result? Players have been driven offshore. Trade groups and market analysis put online slot channelisation at just 20%–40%, highlighting how the restrictive rules have backfired.
Sweden, long a model for licensing, has also seen slippage. The regulator reported overall channelisation around 85% in 2024, with online casino estimated at just 72%–82%. Stringent regulations, such as a ban on bonuses and loyalty programs beyond a welcome offer, drive players to unregulated sites offering better incentives. Policymakers are now reviewing rules to address the illegal market.
“The policy lesson is simple: design rules that keep mainstream players onshore, or the black market will fill the gap.”
A recent report from Yield Sec claimed that illegal operators now command a staggering 71% of the European online gambling market, generating an estimated €80.6 billion in gross gaming revenue. This undermines the licensed industry and deprives governments of billions in tax revenue.

Why players choose the black market – Insights from the UK’s latest research
The UK Gambling Commission’s 2025 research into the illegal online market identifies why consumers turn to the black market: better odds and offers, crypto availability, the ability to gamble while self-excluded, and confusion over which sites are legal.
The Commission notes evidence gaps but accepts that regulation can be one of several drivers toward illegal sites. This is especially true when rules reduce access to desired products or introduce heavy friction.
Independent polling reinforces the point. An Ipsos-based survey on unlicensed gambling sites shows that younger adults are more likely to say that “people like them” might knowingly use unlicensed websites. Fewer KYC checks and fewer restrictions were cited as key reasons.
This perception gap matters. If mainstream customers believe the legal path is slower or of poorer value, they will be tempted to play elsewhere.
How the Cobra Effect takes hold
Affordability checks are a good example of a sound idea that can misfire in practice. Checks protect higher-risk consumers, but intrusive document requests at low spend levels create avoidable friction. Some customers abandon sign-up. Others move to sites that advertise fewer questions and quicker deposits.
Product and price restrictions add a second channel. If in-play markets are removed or turnover taxes force slot RTPs to be lower, many users will look elsewhere. While low limits on bet and deposit sizes aim to protect players, they can push players to unlicensed sites where they can play without such tight restrictions.
Advertising rules can also have adverse effects. Strict ad limits or bans reduce harmful exposure, yet they also reduce the visibility of licensed operators and safer gambling tools. When search results, affiliates, and social media still show unlicensed brands, many customers cannot tell who is authorised and who is not.
What can be done – a path forward for regulators and operators
The goal is not deregulation. It is smart regulation that maximises onshore play while protecting higher-risk players. Regulations should be based on robust data and a clear understanding of player behaviour. The aim should be to create a regulated market that is attractive enough to channel the vast majority of players.
Evidence from higher-channelisation markets points to five best practices.
- Tiered, data-led financial risk checks. Use frictionless, real-time credit and open-banking style signals for low-to-medium spend bands. Escalate to documentation checks only when clear red flags trigger them.
- Competitive, transparent product frameworks. Allow mainstream gambling products with guardrails to reduce harm. Set clear, evidence-based game design standards rather than blanket bans that shift demand offshore.
- Mandatory licence markers. Require visible, standardised licence logos across operator sites, app stores, and payment pages. Pair this with consistent wording on dispute resolution, fund segregation, and safer gambling tools. Consumers should be able to recognise a licensed operator in seconds.
- Payments and platform enforcement. Build channels between regulators, operators, payment processors, search engines, and social platforms. Coordinated payment blocking and ad-platform delisting to reduce the black market’s advantage.
- Publish channelisation as a KPI. Set explicit channelisation targets by vertical and review them quarterly. Proactively adjust the mix of site blocking, payment disruption, and product calibration when numbers slip.
Operators don’t need to wait for legislative changes. They should focus on making their sites attractive and entertaining to compete with the black market. This means offering fair odds, diverse game selections, hassle-free payments and interesting promotions.
Operators should reduce unnecessary friction, making KYC checks quick and straightforward. Publishing payout reports and prominently displaying licensing and security certificates can further build confidence in playing with legal operators.
A clear bottom line
The Cobra Effect in gambling regulation is a design problem. While the intentions behind stricter regulations are noble, the unintended consequences can be severe.
If legal options are slower, thinner or obviously poorer value, a share of play will leak to sites that do not protect consumers. The solution is not fewer safeguards but smarter ones.
The jurisdictions that align regulations to how people actually behave keep players onshore, reduce harm, and protect tax revenue. Those who overregulate watch the black market step in to fill the gaps.
