How casinos use big data for predictions

Why casino forecasts for Big Data

iGaming is a stream of real-time events: clicks, bets, deposits, streams, provider webhooks. Correct forecasts give:

Revenue growth: optimal promos, game releases, personalized offers.
SLO stability: preparation of infrastructure/providers for peak (matches, holidays).
Risk mitigation: payment liquidity planning, limits and anti-fraud resources.
Cost effectiveness: traffic procurement, CDN/clusters, bonus budgets.

What exactly is predicted in the casino

1. Traffic and load: sessions, RPS API/bridge, QoS streams, queue length.

2. Demand for content: lobby/game views, launch games by genre/provider, lobby→game conversion.

3. Finance: deposits/withdrawals, GGR/NGR, bonus liability, cache requirement.

4. Marketing: incremental deposits from campaigns, CPA/ROAS, flight curves.

5. Risk and compliance: expected RG/AML blockages, probability of peak chargeback.

6. Operations: SLA cash registers/providers, WebRTC/LL-HLS degradation probability.

Horizons: real-time (minutes/hours) for automation and short-term (1-14 days) for planning, mid-term (1-3 months) - budgets/contracts.

Data sources and quality

Product events: 'lobby _ view', 'game _ launch', 'bet _', 'round _ settle', QoS.

Financial: 'deposit _', 'withdraw _', 'wallet _', bonuses/wager.

Marketing: UTM, campaign/creative, attribution (post-install, SRN).

External factors: sports calendar, holidays, exchange rates, weather/regional triggers.

Game/payment providers: SLA/statuses, pricing, fraud signals.

Quality (Data QA): completeness, delay (freshness), currency consistency/timezone (UTC in raw materials), deduplication, control of "holes" and bursts. For reliable forecasts, first fix the data - then build up the models.

Big Data Architecture for Forecasts

Ingest: Kafka/NATS (stream) + download batch; raw events in object storage (S3) in immutable mode.

DWH/OLAP: ClickHouse/BigQuery - showcases of facts (bets, payments, sessions) and measurements (players, games, catalogs).

Feature Store: window aggregates (1/7/30 days), holiday/sports features, lags and sliding metrics, categorical game/channel embeddings.

Forecast service: REST/gRPC, near-real-time cache for orchestration (HPA, limits, promo routing).

MLOps: training/validation pipelines, 'modelVer/dataVer/featureVer' versioning, canary calculations, observability.

Fichi: what really works

Time: lags (t-1, t-7), moving averages/medians, STL-decomposition trend + seasonality.

Calendar: holidays by country, sports agenda, pay-days, night/day, weekend.

Behavioral: CTR lobby, share live vs RNG, average check, share of bonus bets, box office failure rate.

Channel: source/creative, show frequency, saturation.

Provider: releases of new games, outage/degradation, table limits.

FX and region: rates and currency baskets, geo/locales.

Models: from classics to hybrids

1. Time Series (aggs):

ARIMA/ETS/Prophet for aggregates (RPS, deposits, GGR) - fast, interpretable.
Hierarchical forecasting: country → brand → channel → game (up/down negotiation).
Plus exogenous regressors (holidays, matches, budgets).

2. ML regression/gradient boosting:

XGBoost/LightGBM/CatBoost by feature: seasonality, lags, promo, providers.
Holds nonlinearities and interactions well.

3. Sequence/Deep:

TemporalFusion/LSTM/Transformer for complex multidimensional series (QoS live, hybrid signals).
Two-tower/seq2seq - for forecasts of demand for games (personalization + units).

4. Causal/Uplift:

For marketing and bonuses: assessment of the incremental effect of campaigns (DR-learner, causal forests), CUPED, geo-experiments.

5. Ensembles & Nowcasting:

Mixtures of models with Bayesian averaging/stacking, nowcasting by early signals (morning trends → day forecast).

Uncertainty and decision-making

P10/P50/P90 Forecasts → Action Rules:

SRE/infrastructure: scale at P90, keep resource buffer.
Marketing - Include the campaign only if the uplift interval is> 0.
Finance: liquidity for payments - conservative (P90 outflow).
Pinball loss (quantile regression) for interval optimization.
What-if scenarios: box office/provider failure, surge in match traffic, exchange rate hikes.

How quality and benefit are measured

Accuracy metrics:

MAE/MAPE/WAPE, sMAPE for aggregates.
RMSE for peak sensitivity.
Coverage/CRPS for probabilistic predictions.

Business Metrics:

Unreleased peak (minus error) → SLO penalties/black; oversupply (error plus) → unnecessary costs.
ROI: Infrastructure/procurement savings, GGR/NGR gains, reduced box office failures, reduced VOID/aborted rounds.

Automate forecast activities

Autoscale: HPA/cluster for P90 RPS, warming up CDN/cache, prefetch assets.

Promo routing: disable/enable channels/frequency limits by probable saturation.

Limits and cash desk: dynamic payment limits and priority rule for expected flows; standby PSPs based on failure forecast.

Game providers: feature flags of tables, control of side-bets/limits on the expected load.

RG/support: operator plan, pro-active prompts and "pauses" for risk segments.

MLOps and operation

Pipelines: daily/hourly retrain, validation of schemes/quality gates (drift, leaks).

Versions and reprods: 'modelVer/dataVer/featureVer', frozen artifacts and dependencies.

Observability: latency of predictions, freshness of features, drift of distributions, comparison of P50 vs fact, alerts to quality split by geo.

Cost control: feature profiling (extraction cost), an attempt to "cheap" models where it is permissible.

Example of storefronts and tasks (schematic)

Showcase 'agg _ finance _ daily':

`date, country, brand, deposits, withdrawals, ggr, bonus_cost, fx_rate, holiday_flag`

Showcase 'traffic _ hourly':

`ts, region, rps_api, rps_bridge, live_qos_rtt, dropped_frames, marketing_spend`

Tasks:

`forecast(rps_bridge, 6h, region=EU) → P50/P90`
`forecast(ggr, 14d, country=DE, exo=[holidays, spend])`
`uplift(deposit_rate, promo=“cashback10”, segment=retained_30d)`

Anti-patterns

Mixing OLTP and analytics on the same database → rates/wallet fall.

MAPE on rows with zeros (instead of WAPE/SMAPE) → a false estimate.

Ignoring external factors (holidays/matches/FX) → systematic errors.

One "magic" global forecast without hierarchy/geo is the loss of accuracy and controllability.

Without intervals - blind, over- or under-scale solutions.

No backtesting/roll-forward - retraining and surprises in prod.

Auto actions without guardrails - extra bones/spam or RG/compliance violations.

Checklist for implementing Big Data forecasts in casinos

Data

Single event contract (UTC, decimal, traceId currencies).
Immovable raw material layer (S3), fact/measurement cases, quality/freshness control.
Feature Store with lags/windows/holiday/sports features.

Models

Basic time-series + exogenous; hierarchical forecasts.
ML regression/ensemble for complex dependencies.
Probabilistic predictions (quantiles), what-if scenarios.
Causal/uplift for campaigns.

Infrastructure and MLOps

Canary imaging, backtesting, drift and latency monitoring.
Artifact versioning, reproducibility, cost-profiling features.
Auto-actions with guardrails (SLO/limits/compliance).

Business and control

SLO/SLA and Accuracy KPI/ROI, retrospective errors.
Kill-switch plan.
Communicating with providers/PSPs about upcoming peaks.

Big Data forecasts in iGaming are not a "crystal ball," but a production discipline: pure event showcases, features, hybrid models, probabilistic intervals and automation of actions with protective frames. Such a system prepares infrastructure and teams for peaks in advance, increases marketing ROI, stabilizes the cash register and reduces risks - all of which are measurable, reproducible and transparent to business and the regulator.
