Everything you need to know about this guide

What is the main difference between Volatility and RTP?

RTP (Return to Player) is a long-term theoretical percentage that tells you how much money a slot is programmed to pay back over its lifetime (e.g., 96%). Volatility (Variance) tells you how that money is paid back: frequently in small amounts (Low Volatility) or infrequently in huge sums (High Volatility). They are independent metrics; a high-RTP game can have any volatility level.

How can I determine a slot's Volatility level?

Slot volatility is not always listed as a number. You can determine it by: Checking the Paytable: Look at the potential difference between the maximum win and the standard five-of-a-kind wins. A huge max win (e.g., 50,000x) indicates high or extreme volatility. Checking Slot Reviews: Trusted review sites usually test and state the volatility level (Low, Medium, High). Experience: If you play a game and experience long dry spells but massive payouts in the bonus round, it is High Volatility.

Which volatility level is best for a smaller or limited bankroll?

Low Volatility slots are strongly recommended for smaller bankrolls. Because they pay out frequently, they help sustain your balance and extend your playtime, giving you more entertainment value and more opportunities to clear wagering requirements before your funds are depleted.

What is the appeal of 'Extreme Volatility' slots, such as those from Nolimit City?

The primary appeal is the potential for an astronomical payout, known as the Max Win Potential. Providers like Nolimit City design these games to push the limits of risk, meaning the bonus features are very difficult to hit, but when they land, they can deliver multipliers far exceeding standard High Volatility games (often 50,000x or more).

Does changing my bet size affect a slot's Volatility?

No. The Volatility of a slot machine is a fixed mathematical setting embedded in the game's code. It remains the same regardless of whether you bet $0.10 or $10. However, you should lower your bet size when playing High Volatility games to give yourself a higher number of spins to survive the dry periods and eventually hit the coveted bonus feature.
