The Use of Large Language Models (LLM) in Online Casino Support

A client who does not receive a response to a request within 10 minutes is likely to move on to another site. In the iGaming industry, a churn rate following a negative experience with the support service is usually higher than in many other niches.

It is logical that Large Language Models (LLMs) are currently gaining importance. This technology is already used by leading operators in the UK, Malta, the Netherlands, and Latin America as an integral part of their operating systems, significantly impacting business processes.

About the Concept

LLM is a class of neural networks trained on large volumes of text data. They can understand human language, generate coherent responses, preserve the dialogue context, and modify the tone of communication depending on the situation.

The most well-known solutions are GPT from OpenAI, Claude from Anthropic, Gemini from Google, and open-source products like Llama from Meta.

In the casino industry, LLM is no longer a typical chatbot with formulaic responses, but an intelligent system that can:

• understand user requests in a free format, without keywords or commands;
• find the necessary information in the knowledge base, FAQ, or CRM;
• generate a personalised response considering the account history;
• transfer complex cases to a live agent with a brief summary of the conversation;
• adapt to new scenarios without complete reprogramming.

The difference between a classic chatbot and an LLM representative is comparable to the distinctions between a call centre of the past generation and a modern service hub. The first responds to individual words and follows the template. The second conducts a full-fledged dialogue and better understands the needs of clients.

Where Exactly LLMs Are Used by the Support Staff in iGaming

The most common option is working with the first hotline. User requests here are typically repetitive: withdrawals, bonuses, verification, technical issues, and questions about payment methods. According to various estimates, these categories account for approximately 60–80% of all messages.

LLM agents close these streams without casino operators' participation. They process inquiries immediately, work 24/7, and avoid queues.

It is important that these models are not limited to canned responses. Before granting them access, the system can access the knowledge base, verify account data via the API, and provide more specific information based on the user's current status.

Authentication and KYC Processes

The Know Your Customer procedure is one of the most sensitive stages of the players’ interaction with the platform, which often creates an additional load on the support team. The main questions typically concern documents, reasons for the rejection of verification, processing times, and the status of the application.

The LLM can guide casino visitors through all these steps by explaining requirements, confirming the receipt of information, and updating authentication status.

However, the model does not make decisions. Its role is to provide support, reducing the number of repeat requests and the load on operators.

Responsible Gaming and Self-Exclusion

This is one of the most regulated and sensitive aspects of digital portal operations. Regulatory requirements (UKGC, MGA, KSA, and others) call for tools to identify risky behaviour and provide users with self-supervision mechanisms.

Large Language Models can:

• recognise potentially alarming wording in the people’s queries, such as signs of stress or impulsive behaviour;
• provide information about RG tools;
• accept self-exclusion requests and transfer them to responsible employees for further processing.

The important thing is that the final decisions in such cases always rest with players, and the LLM solution performs only an auxiliary and information function.

Multilingual Support

Those entrepreneurs who work in several markets face an obvious problem: it is rather expensive to hire a support team for each language. The LLM tool solves this problem — modern models can handle more than 30 languages ​​without any appreciable loss of quality.

If a gambler speaks Polish, Finnish, or Spanish, the agent will respond in kind, taking context into account. This is especially relevant for regions with strict localisation requirements, including the Netherlands, Sweden, and Portugal.

Analytics and Feedback

LLM systems generate massive amounts of structured data on what clients are concerned about:

• what questions are asked most frequently;
• what wording causes confusion;
• where visitors stop and leave.

This information is invaluable material for the product team, UX designers, and marketers.

Architecture of the Models

This aspect is important for operators and technical directors evaluating the expediency of introduction. There are several basic approaches:

RAG (Retrieval-Augmented Generation)

This is the most common architecture for casino support. In this case, LLMs do not store business insights. The model receives them dynamically from the entrepreneurs’ knowledge base.

When gamblers ask questions, the service operates under the following scheme:

1. Search. The neural network transforms the query into a vector and finds relevant fragments in the platform’s database.
2. Context. Fragments are added to the model's request so that it works with relevant information.
3. Response. The LLM system gives the final answer based on the provided context and details.

The advantage of this approach is that the service does not invent facts, but reacts only based on what is available in the database. This is important in an environment where misinformed people about bonuses or verification requirements pose a potential compliance risk.

Fine-Tuning on Domain Data

Some operators and digital portals go further and train the model using the transcripts of conversations, FAQ, and procedures. This improves accuracy and tonal conformity, but requires more resources and regular updates.

For most business owners, RAG is a sufficient and less expensive solution. Fine-tuning is justified if there is a specific domain terminology or unique product scenarios that are difficult to convey through the context.

Agent Systems

The highest level is the solution, which not only answers questions but also performs actions: checks balances, grants bonuses, and cancels transactions. This requires deep integration with the backend and clear permission management. The risks are higher, but so is the automation potential.

Such systems have already been implemented by several large operators, where the LLM agent is authorised to perform a limited set of tasks without human intervention.

Key Benefits for Entrepreneurs

Implementing LLM models offers several advantages for the owners and administrators of gambling platforms:

Reduced Operating Costs

The maintenance of the support team is a significant expense, especially if a casino company operates across multiple markets and time zones. The LLM system makes it possible to handle 60–80% of requests without human intervention, while preserving the quality of response at a stable level.

This does not mean firing the entire team. Agents focus on complex cases that truly require human judgment: appeals, disputes, and problems with responsible gaming. Routine tasks are redirected to LLM.

Scalability without Linear Cost Increases

A peak load (tournament, launch of a promotional campaign, technical issue) for a traditional support team means either a queue or overtime charges.

The system can handle any volume of requests without a decline in quality or additional expenses proportional to the load.

Consistency of Responses

A human team means variability: agents have different experiences, moods, and interpretations of identical situations.

The LLM tool provides the same quality of response at 3 a.m and 3 p.m. This is especially important for compliance-oriented operators, as information on bonuses, limits, and procedures will always be accurate and relevant.

Speed

The average response time of live agents is 2–10 minutes, depending on the workload. Large Language Models respond in seconds. In high-stakes moments (for example, when players cannot make a deposit right away), this can be the difference between retaining customers and losing them.

Regulatory Matters

This is a sensitive topic that online casino owners often underestimate during the implementation phase. The automated support service is subject to legal requirements.

LLM solutions must comply with the following jurisdictional standards:

Transparency and Disclosure

In most countries, regulators either already require brands to disclose to users that they are communicating with AI or are moving toward this requirement. For example, the UKGC clearly emphasises the importance of informed consent. The MGA does not yet have strict rules, but recommends transparency.

In practice, this means that the chat interface must indicate that the system is responding automatically and provide an easy way to connect to the live agent.

Data Protection

LLM systems process personal details of gamblers, which is regulated by the EU GDPR, the UK GDPR, or local laws, depending on the region.

Operators are obliged to:

• have a data processor (DPA) with the LLM provider;
• ensure the compliance of logs with the storage;
• give clients the right to delete the provided details from the program.

The transmission of sensitive information (passport data, card numbers) to external APIs without proper processing is a direct violation of the law.

Responsible Gambling

An LLM that incorrectly processes a self-exclusion request or fails to recognise the signs of ludomania is a regulatory and reputational risk.

When implementing the solution in this area, entrepreneurs are obligated to:

• have precise procedures for transmitting a request to a real person;
• regularly test the model for alarming scenarios;
• document all interactions related to responsible gambling.

The UKGC has already recorded several cases where operators received fines in part due to the improper processing of such requests. Such an excuse as the use of an automated system is not a mitigating factor.

Response Accuracy

The LLM can “hallucinate” — generate confident but false responses. In a casino context, this is especially dangerous: incorrect information about a bonus or terms of withdrawal can create a legal obligation or lead to complaints.

It is important for entrepreneurs to configure the model correctly to avoid problems.

Pitfalls During the Implementation

The use of such models can be associated with several risks and limitations:

Overestimation of the Readiness of the Knowledge Base

A system is only as good as the quality of the data it receives. If the platform’s FAQ is outdated, inconsistent, or incomplete, the program will confuse players.

The application of LLM always means audits and internal documentation structuring. Without this, no provider can achieve satisfactory results.

Lack of Control and Monitoring

Launching an LLM without further control is a mistake. The service should be constantly monitored: it is necessary to review negative reviews, analyse requests to live operators, and verify the accuracy of details after changes to products or rules.

The basic process typically includes weekly examination of logs and regular updates of the referral database.

Failures in Transferring Queries

One of the biggest mistakes is making the transition to a live agent difficult or inconvenient.

If casino visitors get stuck with a bot and cannot exit, it is worse than having no support staff at all. The ability to turn to a real person should be accessible in one step, and the consultant should receive a full summary of the initial communication.

A Disregard of Cultural and Linguistic Context

LLMs can translate well, but they do not always understand the nuances. Players from Brazil and Portugal write in the same language, but have different expectations, slang, and behaviour patterns.

Adjustment of the tonality and local context is a task that cannot be skipped.

Comparison of Approaches: In-House vs Ready-Made Development

There are usually 2 ways to implement LLM into the support service in the gambling market:

Unique Design Based On APIs (OpenAI, Anthropic, Google)

This method has both pros and cons.

The list of advantages includes:

• full control over logic and data;
• flexibility in customisation to business specifics;
• lack of dependence on platform providers.

The disadvantages are:

• the need for a strong technical team;
• requires a long time to launch (3–9 months in realistic scenarios);
• entrusts casino operators with compliance, security, and monitoring issues.

Ready-Made Portals and Solutions

There are several specialised suppliers in the market offering LLM solutions for the iGaming niche: platforms for the automation of support with a built-in RAG architecture, ready-made integrations with popular CRM and chat systems (Intercom, Zendesk, Freshdesk), as well as functionality for compliance documentation.

Key benefits:

• quick start (4–12 weeks);
• less need for in-house development;
• often includes basic conformity files.

Main shortcomings:

• less flexibility in customisation;
• dependence on the provider's roadmap;
• the need to thoroughly check data processing conditions and SLA.

For most medium-sized brands, a ready-made platform tailored to specific requirements is a more pragmatic choice than implementing a project from scratch.

Performance Metrics

Installation without measurements is a waste of money. A basic set of KPIs for LLM support in casinos involves analysing several indicators.

Operational parameters:

• containment rate (percentage of requests resolved without escalation) — the target is 60–75%;
• average first response time (TTFR);
• average deadline for solving an inquiry (TTR);
• cost per closed request.

Qualitative metrics:

• CSAT (customer satisfaction score) for interactions with LLM;
• accuracy rate (percentage of responses confirmed as correct ones during an audit);
• escalation quality (completeness and usefulness of the operator's summary).

Compliance metrics:

• percentage of conversations related to responsible gambling processed in accordance with the procedure;
• number of incidents with incorrect information;
• logging compliance with regulatory requirements.

These metrics should be compared with the base value before implementation. Without analysis, they will be just numbers.

LLM Solution Development Trends

The market of such systems is rapidly growing. Several directions that will shape the next stage of the spread of the service can already be highlighted:

Multimodality

Modern LLM options handle not only texts but also images. In the context of casino support, this means that players can send a screenshot of an error or payment document, and the program will understand what is depicted on it.

This will significantly speed up KYC and technical assistance.

Voice Support

The integration of LLM with voice channels is the next logical step. Several large operators are already testing such agents in their call centres.

The quality of speech synthesis and recognition has reached a level where it is becoming difficult to distinguish a bot from a human. However, the regulatory issue of transparency is even more pressing in this case.

Proactive Support

Today, the system responds to requests. Soon, it will proactively identify gamblers at risk (pending withdrawals, delayed verification, behaviour patterns) and initiate interaction. This is no longer a support, but a retention tool.

Attention of Authorities

Regulators are actively monitoring the market. In 2024–2025, the UKGC started publishing guides on the use of artificial intelligence. This trend will only become stronger.

Those operators who choose to implement LLM without a compliance framework are going to be the first to receive a fine or warning.

Practical Recommendations for Entrepreneurs

If business owners are considering implementing LLM in their support system, here's a sequence of actions that should be carried out based on real-world market experience:

1. Perform an audit of the current state of the assistance team. Learn which categories of requests are received most frequently, what the CSAT is, and which content rate the existing automations have.
2. Review the knowledge base. Check FAQs, procedures, terms, and conditions — everything that will be a source for LLM. Resolve incompatibilities, update obsolete information, and structure it.
3. Determine the limits of automation. Decide in advance which request types LLM can resolve independently and which should be constantly transferred to live agents. Write this in the documentation and configure the system accordingly.
4. Select a deployment model. The choice between in-house development and a ready-made platform depends on the resources, timeframe, and technical maturity of the team.
5. Organise a pilot on limited traffic. Launch LLM with 10–20% of incoming flow of customers, measure indicators, and gather feedback from agents.
6. Provide compliance documentation. It is important to create a DPA, define a procedure for handling responsible gambling requests, implement a logging system, and establish the rules of user information.
7. Scale gradually. After confirming the results of the test phase, expand coverage and add more languages ​​and channels.

The Main Things about Using LLM in Casino Support

Key aspects that operators should take into account:

• LLM is a full-fledged dialogue agent, capable of handling 60–80% of requests without human intervention.
• Multilingualism, 24/7 availability, and consistent responses are not bonuses, but basic features of the system.
• Operating expenses for support are reduced without reducing the quality of service.
• Traffic scaling (tournaments, promotions, peak loads) no longer results in queues or additional costs for technical assistance.
• Agents are exempt from routine tasks and can focus on complex cases that truly require human judgment.
• LLM is ineffective without a high-quality knowledge base. The preparation of documents is the first step that cannot be skipped.
