Under the Spotlight: What slots features are most strongly correlated to increases in player spend, session time, declined deposits and self-exclusion?

The document examines correlations between slot game features and markers of increased gambling involvement and potential harm.

Categories

The research explores how specific features of online slot games are associated with changes in player behavior, particularly those behaviors that may indicate increased gambling involvement or harm. Key findings:

• Game Features Analyzed: Ten slot features were studied, including RTP (return to player), hit frequency, volatility, autoplay ratio, jackpot presence, progressive jackpots, minimum/average bet, spin time, and spin time variation.
• Behavioral Markers Tracked: Five indicators of potential harm were analyzed—daily financial loss, hourly loss, session time, declined deposits, and self-exclusion.
• Volatility Effects: Increased volatility was linked to shorter sessions and faster loss rates, but not to higher total losses or more declined deposits—suggesting a shift in play style rather than increased harm.
• Operator Differences Matter: The relationship between volatility and player outcomes varied across two operators, indicating that product-risk dynamics may differ by player base or game design.
• Methodological Strength: The study used longitudinal panel regression on real-world data from ~2,600 UK players, avoiding selection bias common in cross-sectional studies.
• Call for Further Research: The authors emphasize that methodologies linking game features to harm are still developing and encourage further innovation and critique to refine this research area.

These insights support the need for more nuanced, data-driven approaches to understanding how slot design influences player behavior and risk. For full details, please refer to the complete document.
