In relation to slots, the term "high volatility" is a gaming term that refers to the fluctuations in profit that can occur in a particular game, in this case, in a slot. High volatility slots tend to offer less frequent, but larger wins, while low volatility slots tend to offer more frequent, but smaller wins. This feature is important for you because it ultimately has a role in how often you will win and how large the winnings will be. The higher the volatility, the greater the risk, but also the greater the potential reward.
