Though the two are related, volatility is not the same as hit frequency: hit frequency counts how often something is returned, while volatility describes how much.

Volatility is about how outcomes are shaped, not about what they add up to. Identical RTP does not make two games feel alike: low volatility means small, frequent payouts, and high volatility means rare, large ones. In both cases the long-run return may be identical. For matching a game to a bankroll it is the most useful single property, and comparisons leave it out more than any other.
The common misreading
People often take high volatility to mean ‘pays more’. Rather than paying more, it pays larger amounts less often, so the losing runs between payments are longer too. Moving its return into an outcome most players will never see is all a high-volatility game with a 10,000x ceiling has done; that is not generosity.

Using it in practice
Dry spells are guaranteed by the maths of a high-volatility game, so the bankroll must be deep enough to survive them. Regardless of the ceiling advertised, a high-volatility game is the wrong match for a session budget that cannot absorb eighty losing spins without running out.
You will meet terms such as Volatility on many game pages here, and a term with no studio figure behind it is left open on the page, not filled with a figure copied from a comparison site. Several spec tables on these pages show empty cells for exactly this reason.
A worked example
Consider two games both returning 96%.
Something on about one spin in three might come back from the low-volatility game, usually below the stake. Eighty spins might bring nothing at all from the high-volatility game, which then pays two hundred times the stake. Over a million spins the two converge. Across an evening of three hundred spins the experiences are completely different, and the bankroll requirements are as well.

Not on this site's evidence. The value behind volatility comes from the game's own mathematics, which makes it the studio's and not the operator's, and an unpublished one cannot be backed up by any outside source.
