There is no shared scale
Some studios publish a numeric volatility index, others only a word. ELK rates games out of ten; Nolimit City publishes a figure that regularly exceeds twenty on its own scale. A "high" from one studio and a "high" from another do not describe the same experience.
That is why we show the studio label when it exists rather than converting everything to a scale of our own — a conversion would look tidier and mean less.
Hit frequency matters more than the label
How often a game pays anything at all shapes a session far more than a volatility word. A game paying on 14% of spins feels nothing like one paying on 32%, even when both are labelled high.
When a studio publishes it, that figure is worth more of your attention than the label.
A missing value is not a neutral one
Plenty of catalogues fill an empty volatility field with "medium". It reads as information; it is a guess.
Here, a game with no published volatility shows nothing at all. An empty field is visible and can be fixed; an invented one gets believed.
