How AI helps track casino scams
Fraud in iGaming is many ways: stolen cards, multiaccounting for bonuses, botnets, laundering through "deposit-withdrawal without a game," collusions in live games. Manual checks and simple rules no longer cope: attackers are encrypted for real players, use VPN/emulators and "farms" of devices. This is where AI comes in: models learn from behavioral patterns, build connections between accounts, assess the risk of each operation in milliseconds - and at the same time explain why the decision was made.
1) What types of scams AI catches
Payment: stolen cards, bypassing 3-D Secure, "quick deposit → quick withdrawal," cascades of chargebacks.
Bonus abuse: rings of accounts under welcome/blind, "washing" bonuses on low variance, pattern betting cycles.
Multi-account/identity spoofing: device/network matches, proxy networks, fake KYCs.
Collusions and bots: synchronous patterns in live/games with interaction, autocliques, ROS scripts.
AML/doubtful transactions: abnormal sources of funds, short-cycles of deposit-withdrawal, sanctions/RAP risks.
Crypto risks: hot wallets without history, tainted entrances, pre-deposit mixing attempts.
2) Data and signals: from which the anti-fraud model is "boiled"
A. Player behavior (event stream)
sessions, depth and rhythm of bets, transitions between games, "pace" and variability;
changes in habits: time zone, device, payment method.
B. Technical Profile
device-fingerprint (GPU/sensors/fonts/canvas), emulators, root/jailbreak;
network: IP/ASN, mobile proxies, TOR/VPN, shift frequency.
C. Payments and finance
BIN/wallet, retreat by decline codes, split deposit, "carousel" methods;
turnover velocity, atypical amounts/currencies.
D. Connections and Graph
intersections by devices/addresses/payment tokens;
"community" accounts (community detection), the path of money.
E. Documents/Communications
KYC validation (linearity of metadata, "seams" in the photo), support behavior (pressure, scripts).
3) Models and when to apply them
Supervised (supervised learning): gradient boosting/neural networks for "known" scenarios (chargeback fraud, bonus abuse). Requires marked history.
Unsupervised/anomaly detection: Isolation Forest, Autoencoder, One-Class SVM - finds "dissimilar" sessions, new schemes.
Graph models: GraphSAGE/GAT, label propagation, and rules over the graph to identify multi-account rings.
Behavioral biometrics: RNN/Transformer in micro-cursor movements/input timings → distinguishes a person from a bot.
Sequence/temporal: LSTM/Temporal Convolutional Networks - catch temporary deposit-rate-withdrawal patterns.
Rule + ML (hybrid): fast deterministic stop rules (sanctions/PEP) + ML-scoring risk; champion/challenger.
4) Features that really work (and "break" a little)
Velocity-signs: deposits/withdrawals/bets per window (1m/15m/24h), unique games per session.
Diversity/entropy: variety of bets and providers; low entropy = "script."
Sequence gaps: intervals between actions, "metronome" of clicks.
Device stability: how many accounts on one device and vice versa; frequency of fresh "glands."
Graph centrality: the degree/intercentrality of a node in the "family" of accounts/wallets.
Payment heuristics: retray with an increase in the amount, splitting payments, repeating BINs between "unrelated" players.
RTP deviations per player: oddly stable winnings with "perfect" bet selection.
5) Real-time architecture: how to catch in milliseconds
1. Event streaming: Kafka/Kinesis → aggregates over time windows.
2. Feature Store: online features (velocity/uniqueness/entropy) + offline for training.
3. Model serving: gRPC/REST scoring <50-100 ms, fault tolerant replicas.
4. Action engine: three response levels - allow/step-up (2FA/KYC )/block & review.
5. Feedback loop: total markup (chargeback, confirmed abuse), auto-relebeling and periodic retreat.
6. Explainability: SHAP/feature attribution → the reason for the decision is in the ticket.
6) Explainability, fairness and reduction of "spoons"
Reasons in one screen: show your support top features that "pushed" the risk (IP cluster, device-share, velocity).
Two-stage pipeline: a soft ML filter → a strict rule only for a combination of factors.
Geo/device verification: Give a chance to go step-up (2FA/KYC) before banning.
Bias test: do not punish players for living in "cheap ASN" in itself; factor = set of signals.
Human-in-the-loop: complex cases - in manual verification; the results are returned to the dataset.
7) Quality metrics (and business metrics)
Model: Precision/Recall/F1, AUROC/PR-AUC, Kolmogorov drift.
Business:- Fraud capture rate (share of caught events), False Positive Rate (share of honest under attack), Approval rate (share of "allowed" deposits/conclusions), Chargeback rate and Cost per case, Time-to-detect, share of auto solutions without escalation, Impact on LTV/Retention (how many honest ones left because of friction).
Important: optimize the cost-sensitive function: the price of skipping fraud>> the price of manual verification.
8) Application cases (short)
Bonus abuse rings: graph + XGBoost in velocity → revealed clusters of 40 + accounts on mobile proxies, a step-up block before KYC confirmation.
Chargeback fraud: sequence model catches "deposit-loading bets-withdrawal request <20 min" + BIN pattern → hold & KYC.
Collusions in live: synchronous bets at the end of the window, similar deviations from RTP in the "team →" table limitation, manual review.
Crypto risks: on-chain heuristics + behavioral scoring → increased confirmation/escrow limit on output.
9) How not to turn anti-fraud into an anti-user experience
Step: the lower the risk, the softer the friction (2FA instead of full KYC).
Minimum repeated requests: one "KYC package," checklist immediately, clear deadlines (SLA).
Transparent reasons: a short explanation of "what's wrong" without revealing anti-fraud secrets.
Whitelisting: Stable, long-proven players - less friction.
Channel consistency: cabinet decision = same decision in support/mail (no "two realities").
10) Compliance and privacy
Data minimization: collect only what you need; keep the agreed terms.
GDPR/local norms: legal grounds, rights of the subject (access/correction/appeal to the "auto-decision").
Security by design: access by role, HSM for keys, magazines, pentests.
Inter-operator exchanges: if you use - only hashes/pseudonymization, DPIA and exchange agreements.
11) Step-by-step plan for the introduction of AI anti-fraud (for the operator)
1. Risk and Rule Map: Define red lines (sanctions/PEP/AML) and KPIs.
2. Collection of events and features: a single log-skhema, feature store, data quality control.
3. Baseline model + rules: fast hybrid, running in "shadow" mode.
4. Evaluation & calibration: backtesting, offline → online A/B, selection of thresholds by cost-matrix.
5. Explainability + support runbook: ready-made cause texts, escalation routes.
6. Retraining and monitoring: drift alerts, champion/challenger every X weeks.
7. Audit and security: decision logs, accesses, DPIA, regular penetration test.
12) System maturity checklist
- Real time scoring <100ms and fallback mode.
- Online features (velocity/graph) + offline training, dataset versioning.
- Explainable output for support (top features/SHAP).
- Cost-sensitive thresholds and step-up/manual SLAs.
- Drift monitoring and auto-recalibration.
- Privacy policies, DPIA, minimizing access to raw data.
- Documented appeal rules for players.
AI in antifrode is not a "magic button," but an engineering system of data, features, models and processes. It improves accuracy, accelerates reactions and reduces manual load, but only if it combines ML, rules, graph analysis, explainability and compliance. A mature approach gives the main thing: less losses from fraud and less friction for honest players.
