🛠️ Guide: How to Use This Slot Volatility & RTP Tool:

Example: Analyzing a Game

Let’s say you’re looking at a slot with the following values:

• RTP: 96.2%
• Volatility: High
• Bet per spin: €1

You’d see the following output:

• Expected Return Per Spin: €0.962
• House Edge: 3.8%
• Volatility: High risk – big wins possible, but rare

This gives you a clearer understanding of the game’s risk vs reward balance.

Why RTP & Volatility Matter

🎯 RTP – Return to Player

RTP is the foundation of slot math. A game with 96.5% RTP means that, over thousands of spins, players can expect to get €96.50 back for every €100 wagered. It doesn’t guarantee short-term results but is essential for comparing game value.

⚡ Volatility – Risk Level

Volatility (also known as variance) determines how often and how big a slot pays out:

• Low Volatility: Frequent, small wins (e.g., Starburst)
• Medium Volatility: Balanced frequency and win size
• High Volatility: Rare wins, but large when they hit (e.g., Money Train 4)

Choosing the right volatility depends on your bankroll, risk appetite, and playing style.

Understanding the Results

When you use our calculator, you get these key insights:

• Expected Return Per Spin: What you should win back on average per €1 bet
• House Edge: The casino’s profit margin (100% – RTP)
• Volatility Classification: A qualitative analysis of risk

This makes it easier to compare games, spot high-risk titles, and avoid low-RTP traps.
