Game Lobby Optimization

**TL;DR:** Game Lobby Optimization is the casino product practice of curating, ranking and personalising game tiles in the lobby to maximise engagement, bet frequency and GGR per active session.

What it means

A casino lobby with 4,000+ titles is overwhelming. GLO uses placement, ranking, categorisation and personalisation to surface the right games to the right players. Top operators run ML-driven recommendation engines (Smartico, Fast Track, Optimove, or in-house) similar to Netflix/Spotify, ranking games by player taste, RTP preference, volatility profile, time-of-day, and recent play history.

GLO also covers fixed merchandising: feature carousels for new releases, top-grossing rows, "popular in your country," provider co-marketing slots, and jackpot game highlights.

Formula / How it's measured

GLO KPIs: games-per-session, average bet size, recommendation CTR, GGR per impression, return rate to recommended games.

Example: an operator A/B tests a new ML-personalised top row vs a manually curated "popular now" row. Personalised variant: CTR 18% vs 11%, GGR/session +14%, session length +9%.

Why it matters for operators

In a 3,000+ game library, 80% of GGR typically comes from 50–150 games. Surfacing them effectively is worth millions in GGR. Personalised lobbies also lift retention by reducing the "I can't find anything to play" drop-off. Conversely, a static, provider-pushed lobby leaves significant revenue on the table.
