OASIS and the Player Self-Exclusion File: How Exclusion Works in Germany

OASIS is the central, cross-operator player self-exclusion file maintained in connection with the German states' gambling supervision. An exclusion recorded in this system applies across operators, not just at a single provider — that's the key difference from a self-exclusion set up directly and exclusively with one specific betting site or casino.

Three Types of Exclusion

According to the GGL's official description of the GlüStV 2021 player protection measures, the system provides for three distinct exclusion mechanisms, differing in duration and who triggers them:

Short-term exclusion (the "panic button"). A 24-hour block that expires automatically. Suited to situations where someone wants a short break from gambling without going through a longer-term process.
Self-exclusion. An exclusion initiated by the player themselves, with a minimum duration of 3 months.
Third-party exclusion. An exclusion that can be initiated by, for example, a family member, with a minimum duration of 12 months.

Both of the longer-term exclusion options — self-exclusion and third-party exclusion — run through the central self-exclusion file and are free of charge for players.

Who OASIS Is Relevant To

OASIS and the self-exclusion file behind it aren't only relevant to people considering an exclusion for themselves. Family members concerned about a loved one's gambling behavior can also act, through third-party exclusion. And for anyone using a betting site or online casino in Germany, it's worth knowing that a licensed operator is legally obligated to honor this system — an operator that didn't would be violating a core precondition of its German authorization.

Why a Central, Cross-Operator Exclusion?

The core purpose of the self-exclusion file is to stop an excluded person from simply switching to a different operator and continuing to play there unimpeded. An exclusion registered only with a single operator wouldn't achieve that — it would only block access to that one operator, while every other licensed operator would remain open. Because the exclusion works centrally, it instead takes effect simultaneously at every connected, licensed operator.

Extended Beyond the Online Space

One important, often-overlooked detail: the self-exclusion file was expanded by the Glücksspielstaatsvertrag 2021 and no longer covers only online gambling — it now also covers gaming halls, restaurants with gaming machines, and betting shops. An exclusion can therefore also affect access to physical, land-based gambling offerings in Germany, not just online platforms. For more on the legal framework mandating this expansion, see our guide to GlüStV 2021.

Part of the Mandatory IT Systems

The self-exclusion file is part of the mandatory IT systems that licensed operators are required to run under GGL rules. That means an operator holding a valid German authorization is obligated to connect to this system and honor exclusions — participation isn't a voluntary extra, it's a legal precondition for obtaining and keeping the authorization at all. That applies regardless of whether the product is sports betting, online casino games, online poker, or virtual slot machines.

Additional, Individual Limits at Specific Operators

On top of the central self-exclusion file, players can often also set individual deposit, loss, and time limits directly with a specific operator — limits that can sit below the legally mandated cross-operator ceiling of €1,000 per month (supplementing that ceiling with a lower individual limit, not replacing it). More on this in our player protection guide. These individual limits are distinct from the exclusion system described here: a limit caps how much you can deposit or lose, while an exclusion blocks access to play altogether.

What an Exclusion Means Day to Day

For someone who registers an exclusion, the practical effect is this: every attempt to register or log in with a licensed German operator triggers an automatic check against the exclusion, and access is denied. That works regardless of whether the person ever had an account with that specific operator before — the check happens centrally, not just against one operator's own existing customer records. That consequence is intentional: the goal is to provide a genuinely effective tool, not just a symbolic gesture.

Where to Register an Exclusion

This editorial team has not independently verified a direct registration link for OASIS and instead refers readers to the GGL's official site for current contact and registration information. We'd rather point to the primary, official source — which will always be more current than a summary like this one — than offer a link here that could be outdated or wrong.

Why an Exclusion Is a More Effective Tool Than Willpower Alone

A common misconception is that player protection is purely a matter of personal willpower. The self-exclusion file deliberately takes a different approach: it shifts the responsibility for enforcing a limit away from the individual and onto a technical, legally mandated system. That matters most in exactly the moments when a person's own decision-making might be most affected by the gambling situation itself — precisely when a limit based purely on self-discipline would be least reliable. By placing enforcement with operators who are legally required to check every login against the exclusion file, the system creates a safeguard that still works even if a person is, in that moment, trying to get around it.

How This Fits With Other Player Protection Measures

OASIS, or the self-exclusion file, is only one of several tools mandated by the Glücksspielstaatsvertrag 2021. Together with the cross-operator monthly deposit ceiling of €1,000, the ban on simultaneous play across multiple operators, and the mandatory systems for early detection of risky gambling behavior, the exclusion file forms a layered protection system. None of these tools replaces the others — a player might have an individual deposit limit set with one operator without being registered in the central exclusion file, and vice versa. For the full picture of every measure, see our guide to player protection in Germany.

A Practical Example

To make the difference between an operator-specific exclusion and a central one more concrete, consider a simple example: suppose someone has an account with one betting site and decides to set up a self-exclusion. If that exclusion were registered only with that one operator, the same person could open a new account with a different licensed operator the very next day and keep playing without restriction. Because the exclusion instead runs through the central self-exclusion file, an attempt to open a new account with a different connected operator is also automatically rejected — regardless of the fact that the person never had an account there before. That's the practical core of what "cross-operator" means in this context, and the main reason this system works differently from a simple account block.

What an Exclusion Is Not

Just as important as understanding what an exclusion does is understanding what it isn't. Registration in the self-exclusion file is not a statement about a person's creditworthiness, not a criminal-law measure, and not a publicly viewable record. It's purely a gambling-regulatory tool with the single purpose of blocking access to licensed gambling offerings in Germany for the duration of the exclusion. Once the applicable minimum duration has passed, the exclusion doesn't necessarily end automatically — the exact procedure for extending or ending it should be confirmed directly with the responsible body, since this editorial team can't offer its own independently verified details on that process.

Frequently Asked Questions About OASIS and the Self-Exclusion File

Can I have an exclusion lifted early?
This editorial team hasn't researched officially confirmed details on the exact procedure for an early lift, and points readers to the GGL's official site or the responsible body for this as well.

Does an exclusion apply to foreign, unlicensed operators too?
The self-exclusion file is tied to licensed operators connected to the system. An operator without a German authorization isn't necessarily connected to it — one more reason the distinction between licensed and international operators on our site matters. See our international operators overview for more.

Does a self-exclusion or third-party exclusion cost anything?
No, both exclusion types are free of charge for players, per the GGL.

What's the difference between the 24-hour block and self-exclusion?
The 24-hour block expires automatically and suits a short-term pause, while self-exclusion, with its 3-month minimum duration, represents a more deliberate, longer-term step.

Can someone else register an exclusion against my will?
Third-party exclusion exists exactly for that purpose — for example, initiated by a family member — with a minimum duration of 12 months. Specifics on the exact procedure should be confirmed directly with the responsible body.

Do I need to give a reason to self-exclude?
This editorial team hasn't researched officially confirmed details on the exact application requirements. For binding guidance on the procedure, we point readers to the GGL's official site.

A Note on How Current This Information Is

The exact procedures and timelines around the self-exclusion file can change with future amendments to the Glücksspielstaatsvertrag. This guide reflects the state of things as of the check date shown below, and doesn't substitute for binding guidance from the responsible bodies.
