"Average volatility" is a term used in the world of online slots to describe fluctuations in gameplay. It refers to the frequency and amount of wins that you can expect from any particular online slot. Slots rated as having medium volatility tend to offer a solid balance of smaller, more frequent wins and larger, rarer wins. This means players don't have to wait too long to hit a win, but also don't risk losing their entire bankroll in a single spin. It is important to note that a slot's average volatility is an indication of how often wins can be expected, but does not guarantee that every spin will yield a win.
