One table for the whole catalogue. The left half is the studio's own published figures. The right half is ours — recorded spin by spin at a fixed bet — and it is blank for every title the rig hasn't reached yet. Click any column to sort.
Leaderboards open at 4 recorded sessions — ranking fewer than that would look like statistics without being any. One session recorded so far.

Vol Index is a dispersion figure computed from a recorded session — not a provider's marketing label. It exists so "Medium", "High" and "Extreme" stop meaning five different things depending on who wrote the copy.
Vol Index = population standard deviation of per-spin net result, in units of the fixed test betBigger swings per spin push the number up; long stretches of near-identical small results keep it low. Computed the same way for every session — see how we test.
The number comes out of the recorded spins. A game the rig hasn't reached shows nothing in that column — not an estimate, not a placeholder.
No per-game adjustments. If a number looks odd, it is still the same calculation that produced every other number here.
Dispersion measured over a few hundred spins describes that run. It is a comparable figure, not a final verdict on the game.
As sessions land, more rows fill in on the right-hand side. The calculation itself stays put.
It holds one row per recorded session, and nothing else. The catalogue has 3,831 playable demos; 1 has been through the rig so far. A game with no session has nothing measured to show, so it is not listed here — it sits in the catalogue with the studio's own figures.
Volatility, RTP and max win are the provider's own published figures, carried over as they are. Hit rate, best win, Vol Index, dry streak and spin count come from our own recorded sessions. The table header marks the split.
No. The provider's label is their classification. Vol Index is computed from actual recorded dispersion using one public formula, so it is comparable across studios that each describe volatility differently.
Not yet. Everything we have measured is on this page and on each game's own session page. Spin-by-spin logs and a machine-readable export are not published at this stage.
