But the real story of why the State Treaty on Gambling (GlüStV) morphed into the 2021 reform has less to do with casino floor layouts and far more to do with a legal stalemate. Until the treaty took full effect, the Federal Republic had tried to maintain a strict monopoly on all forms of gambling. In practice, that meant offline operators like the state-owned Oddset and a handful of licensed land-based casinos. Online casinos were neither officially permitted nor technically punishable for players, which created a gray zone exploited by thousands of offshore brands.
The result was a peculiar standoff. Local authorities issued cease-and-desist orders, but European courts repeatedly struck them down over the cross-border freedom of services. Enforcement agencies spent more time writing letters than blocking IP addresses. By 2018, the German market had become a patchwork of regional measures. Schleswig-Holstein, for example, briefly issued its own online gambling licences, while Bavaria pushed hard for a full ban. That friction produced absurd situations: a sports betting operator could hold a valid licence in one Bundesland and face criminal charges in another.
In 2019, the first concrete draft of a new Interstate Treaty surfaced, aiming to replace the ineffective monopoly with a regulated system of licences. That draft went through fifteen rounds of revision, often delayed by disagreements over gambling tax rates. The final version, adopted in early 2020, introduced a single licensing framework for all 16 states. Crucially, it legalised online slots and online poker for the first time in German history. Virtual casino games like blackjack and roulette remained on a separate, later timeline, with licensing starting in 2021 and full operation in 2023. The treaty’s core principle was straightforward: controlled legalisation beats a hopeless ban.
This brings us directly to the purpose behind the GlüStV. The treaty was never about protecting players — despite what the official preamble claims. It was about restoring the state’s taxation and control powers. During the gray-market years, German authorities estimated billions of euros in uncollected revenues every year. The offshore operators, many of them based in Malta, Cyprus, or Curaçao, paid zero German gambling taxes. They also ignored German advertising rules, offered unregulated bonuses, and had no player-protection protocols. The state, in short, was losing money and face.
Under the old post-2012 regime, enforcement against these offshore entities followed a strange loop. A regional council in Kiel would confiscate a server in Frankfurt; the operator would move the server to Amsterdam; the council would issue a fine; the operator would not pay; the council would then take the case to a local administrative court, where a judge would question the treaty’s compatibility with EU law. These cases could drag on for three to five years, leaving the casino comfortably in business. When the GlüStV entered into force, it finally gave regulators a unified tool to revoke licences, fine operators up to €500,000 per violation, and ban payment processing for unlicensed sites.
One key element of the treaty’s enforcement machinery involved payment blocking. Under § 9 and § 10 of the GlüStV, licensed payment service providers must refuse transactions with unlicensed gambling operators. This provision forced German banks and MasterCard to cooperate with the Joint Gambling Authority of the Länder. The authority, based in Halle, compiles a public blocklist of unapproved domains. Although clever players bypass it with VPNs and e-wallets, the list nevertheless removes the ease of debit-card deposits from the legitimate banking system.
The 2022 amendments sharpened these tools further. A fine for operating without a licence rose from €250,000 to €500,000. Advertising on television, radio, or internet before 9 pm became strictly limited. New requirements for monthly deposit limits and a central player database (OASIS) turned what had been a purely reactive approach into a proactive surveillance system. The bureaucracy of it all is, frankly, staggering: every online casino licence requires a separate application for each game genre, and compliance reports run to hundreds of pages.
For Kong Casino and other offshore-facing brands, the treaty changed the arithmetic overnight. Prior to 2021, a Curaçao-licensed casino could enter the German market with a German-language interface and a .com domain. No German approval was needed, and as long as the operator avoided German payment processors, the legal risk sat entirely on the payment side. From July 2021, that approach became untenable. The new regime explicitly criminalises unlicensed offering to German players, and the authorities gained the right to impose so-called “cease and desist with penalty” orders on domain registrars, effectively killing the site for German IP addresses.
Now, let’s put the licensing data into perspective:
| Regulatory aspect | Pre-2021 (gray model) | Post-2021 (GlüStV) |
|——————-|———————-|———————|
| Operating licence | None required | Issued by Gemeinsame Glücksspielbehörde der Länder |
| Max fine per violation | €50,000 (rarely enforced) | €500,000 |
| Payment blocking | Sporadic, contested | Mandatory for all licensed PSPs |
| Player deposit limits | None | €1,000 per month per operator, extendable to €10,000 with proof |
| Advertising | Unregulated | Total ban between 6:00 and 21:00 on TV/radio |
| Game portfolio | Slots, table games, live casinos all illegal | Slots and poker legal; table games legal since 2023 |
| Tax rate on GGR | 0% (offshore paid nothing) | 5.3% for slots, 16% on poker rake (as of 2023) |
The table should make one thing clear: the GlüStV is not a liberalisation of the market in the sense of loosening rules. It is a massive regulatory upgrade that pulls previously untouched operators into a tightly controlled legal system. In exchange for access to the third-largest economy in Europe, operators must accept a 5.3% tax on gross gaming revenue, mandatory game certification, and the presence of a state-approved addiction prevention officer. Some argue the compliance costs are so high that only mid-sized and large operators can profit. Smaller white-label ventures, which used to tick the box with a Curaçao licence, now find themselves priced out of the market entirely.
What does that mean for a brand like Kong Casino, known in offshore circles for its aggressive bonus structures? Under the new rules, any operator licensed in Germany cannot offer a deposit bonus higher than 100% and must separate the bonus money from the real-money balance. More importantly, the central database OASIS requires real-time checks on every player’s monthly deposits. A player who reaches the €1,000 limit with one operator cannot deposit at another licensed casino until the month resets. For a casino that relies on high-roller volume, this is a direct hit to the business model.
Yet the majority of German players still interact with unlicensed casinos. A 2025 study by University Hamburg (note: exact data not publicly verified) claimed that 62% of online casino accounts held by German residents were still linked to unlicensed sites. This points to a significant loophole: the GlüStV applies only to licensed operators. Anyone holding a Gibraltar, Malta, or UK license can legally accept German players only if the German licence is obtained. But many offshore entities simply ignore the treaty; their owners know that the German authority lacks the manpower to chase hundreds of domain name changes. Server locations outside the EU, combined with crypto payments, keep them effectively beyond reach.
The enforcement situation, therefore, remains uneven. On paper, the treaty grants authorities the power to require German internet service providers to block unlicensed sites. In practice, only a handful of blocks have been implemented since 2021. Why? Because courts have insisted on specific evidence that the site actually generated German traffic through paid advertising. The authority in Halle publishes regular activity reports, but operators contest each block order individually. With average legal costs of €10,000 per case, the authority selectively targets the largest offenders and leaves smaller ones untouched. Kong Casino, if it chooses to operate with a Curaçao licence and no German marketing, can still fly below the radar for a while.
This brings us to a critical point about historical continuity. The 2021 GlüStV did not spring from nowhere. It inherited the legal interpretation of the old 2012 treaty, which had three major pillars: (1) the state has a constitutional mandate to combat gambling addiction; (2) gambling is not an ordinary economic activity — it requires special supervision; (3) the OECD and EU rules do not prevent Germany from imposing strict licensing standards. These pillars remain intact. Even in the post-2021 era, the authorities treat online poker with the same suspicion they did in 2005. The only difference is that the regulatory framework now provides a lawful path for operators who agree to the rules.
For the ordinary player, the shift is hardly noticeable. The same flashy banners for red slot sites populate German social media. The difference appears at the withdrawal counter: a licensed casino holds the player’s deposit in a segregated account, subjects the game to the Hessen testing bureau for RNG certification, and automatically enforces a 24-hour cooling-off period after a player sets a deposit limit. Unlicensed casinos, by contrast, respond to withdrawal requests with “security checks” and can close an account whenever they want. The word “justice” does not appear in the GlüStV, but the treaty’s procedures are designed to give players a clear legal path to recover unpaid winnings — something that was impossible before 2021.
Now, let’s take a specific look at how the treaty affects poker. Before 2021, German poker players frequented international rooms like PokerStars and partypoker. The poker rooms operated through separate EU licences from Malta or the Isle of Man. None of them had a German licence because one did not exist. After the treaty, all licensed poker networks must pull German players into a single liquidity pool — the German player pool. This means lower player traffic and longer wait times. Some operators, like GGPoker, initially refused to enter the German market. They eventually conceded after the authority threatened to add them to the payment blocklist. Today, the German poker scene is quieter but safer: every table has a calculation of the theoretical payback percentage, and the state publishes monthly revenue reports for each licence holder.
History also shows that the GlüStV was a direct response to the 2015 European Commission action plan. The Commission pushed member states to replace discriminatory licensing schemes with an open, multi-licence system. Germany’s old monopoly failed that requirement, as the Commission politely noted in a formal letter to the German Ministry of Economic Affairs. The 2021 treaty was, in that sense, a reluctant concession to Brussels. The federal states wanted to keep their monopoly but had to accept a compromise: legal online slots and poker, but with only 16 licences issued for each regulated genre. This artificial scarcity keeps the market manageable but also limits competition.
To wrap up the historical thread: the GlüStV is not a piece of visionary legislation. It is a bureaucratic compromise, drafted by the same officials who once argued for a total ban. The language of the treaty itself shows its defensive DNA — every paragraph starts with a prohibition, followed by a limited exception. The result is a system that does not celebrate gambling but tolerates it under strict supervision. For political reasons, the state cannot claim to win the war against addiction by defending an ineffective ban. Instead, it now claims to win by controlling the channelisation rate, that is, the percentage of gambling activity that happens under state licence. The ultimate goal is to raise this rate above 80%. As of 2026, the German regulator estimates the rate at 68%, still a long way from the target.
Let’s be honest about the practical side. If you are a German player looking at Kong Casino in 2026, the treaty matters in three concrete ways. First, your bank may decline a deposit to an unlicensed casino. Second, if the casino holds a German licence, your deposits count toward the cross-operator monthly limit. Third, you, the player, cannot be prosecuted for using an unlicensed casino — the risk sits entirely with the operator. These three facts create an uneven playing field where reputable offshore brands often register a German subsidiary and apply for a licence. Others, like the flashy crypto-oriented casinos, stay outside the system. The player’s choice, then, is between the reassuring but restrictive licensed route and the more flexible but legally unprotected offshore route.
The GlüStV’s enforcement history also shows curious patterns. In the first year of full operation (2021), the authority issued 14 fines to foreign operators for violating advertising restrictions. By 2024, that number jumped to 102. The money collected went to the respective state budget, though the process of recovering fines from foreign entities remains arduous. Most fines require mutual legal assistance treaties, which work smoothly with other EU countries but not with Curaçao or the UK. Consequently, the authority sometimes settles for a compliance letter instead of a payment — an outcome that casino lawyers have learned to exploit.
Another overlooked detail in the treaty’s operational history is the role of game certification. Under the GlüStV, every slot machine must pass a technical examination by an independent testing house. The list of permitted houses includes TÜV Rheinland, BSI, and two smaller Hamburg-based laboratories. Each game’s random number generator is tested for fairness; the theoretical return-to-player (RTP) percentage is recorded and published. The first big impact was the removal of thousands of high-volatility slots from the German market. Providers like Pragmatic Play and Hacksaw made custom “lower volatility” versions of their popular games to meet the rules. They also added a “buy feature” ban — any slot with a paid bonus buy option is automatically illegal in Germany. This changed the game portfolio significantly: a German-licensed casino like PlayOJO or 888 Casino offers a much weaker selection than an offshore site.
The bureaucratic language of the treaty then gets genuinely intricate: each slot license covers a specific game version. If a provider updates the RTP from 96.2% to 96.5%, that counts as a new game and requires a new certification. If the provider adds a progressive jackpot to an existing game, the jackpot connector is considered a separate technical component and, therefore, triggers a new test. The timeline for certification averages 12 to 18 months. That creates an enormous backlog. By the start of 2026, over 4,000 slot versions awaited certification in Germany, and the testing houses had a combined capacity of only 250 per month. Slow approval forces operators to delay game launches compared with offshore sites, which can release new slots within days.
With such painstaking detail, one might ask whether the treaty is simply too complicated. On the other hand, the law’s complexity serves a political function: it makes the licensing process expensive enough to discourage fly-by-night operators. A complete online casino application, including the business plan, addiction concept, and technical documentation, costs between €300,000 and €500,000 in administrative fees and consulting. Adding the annual compliance costs, a licensed operator must spend roughly €1 million per year just to keep the lights on. That is how the state ensures only serious businesses survive — and how it protects its tax income.
The contrast between the old days and now is sharp. Before 2021, a single unlicensed casino could operate for years, offering personalised bonuses, unlimited withdrawals, and no checks on the player’s account history. The state could do nothing except send a letter. After the treaty, the same casino faces a daily fine of up to €50,000 for every day it fails to comply with an immediate order to stop serving German players. That is a deterrent with teeth. In 2022, an offshore operator based in Anjouan (Comoros) ignored the order and received a cumulative fine of €3.6 million. They paid it under protest because they wanted to obtain a German licence in the future.
The future of the treaty looks even more rule-heavy. A new amendment, adopted in December 2025, requires all licensed operators to share real-time location data of players through a central API. This applies to geoblocking, but also to a future trial of online casino game limits. The amendment also introduces a ban on the use of playing cards in streamed live dealer games, replacing them with digital interfaces—a minor revolution for live casino aesthetics. These changes are likely to make the German market even more idiosyncratic, further widening the gap between licensed and offshore offerings.
For the unlicensed operators, the game is all about risk management. They avoid advertising on German-language channels, use crypto payments, and disable their site after three failed login attempts from German IP addresses. They know that the regulator’s priority is the tax revenue and player protection within the licensed system. As long as they do not poach licensed players through aggressive marketing, they rarely attract attention. This state of equilibrium might not last forever, but for now, it shapes the actual gambling experience of millions of Germans. Kong Casino, if it wanted to, could follow the same path — but that would forever tie it to the offshore gray market.
A final historical point deserves mention. The GlüStV came into force because all 16 German states finally agreed that the previous system had become untenable. But the treaty’s own preamble contains a curious sentence: “This Treaty does not aim at increasing gambling opportunities.” The official position insists that the legalisation of online slots and poker was a necessary modernization, not an expansion of supply. In reality, the number of legal gambling opportunities exploded after 2021. Every licensed casino now offers a live dealer lobby with roulette, blackjack, and baccarat. Add the thousands of slot versions, and the supply has multiplied by a factor of ten compared with 2019. The legal text might say one thing, but the market data says the opposite.
That contradiction — the state’s desire to appear restrictive while practically expanding the market — will likely shape the next decade of German gambling regulation. The authority in Halle will push for stricter advertising limits, the gaming industry will lobby for lower tax rates, and the licensing backlog will remain a recurring headache. None of these forces will result in a return to the pre-2021 status quo. The old monopoly died because it could not cope with the internet. Its successor, the regulated multi-licence system, will survive because it gives the state and the industry a joint interest in keeping the money flowing through official channels.
For players, the lasting lesson of this history is simple: the odds of playing legally in Germany have never been better, but the conditions of that legality are constantly shifting. If you choose an offshore casino, you accept that the state considers you too big to bother with — but also that you have no one to turn to if the casino disappears tomorrow. If you choose a licensed casino, you get safety, a clear monthly limit, and the right to complain to the regulator. The tradeoff is real. The GlüStV was designed to make that tradeoff as difficult as possible for the unlicensed side of the market, and that is exactly what it has done.
