The data behind the score

Everything we measure, and what we refuse to claim.

What we read, and what it produces

Every operator is measured against the same sources, and none of them are sources an operator controls. That is the whole reason the number is worth anything.

What Niekie reads, and what each part produces Five kinds of independent source feed into Niekie's scoring, which produces a single number out of 100 that is sealed to a public audit ledger. Separately, the casinos' own public bet feeds are read and counted to produce observed return figures, which are published on their own and do not affect any score. License registries Sanctions lists Player payout reports Domain records Complaint history niekie 0 to 100 sealed to the ledger Casino bet feeds Observed return published, never scored
Independent sources in, one number out, and no operator can pay to change what happens in the middle. What a casino publishes about its own games is counted separately and kept out of the score, because it is the one input an operator controls.

What we are watching right now

Bets read from each operator's own public feed, counted by us. Return is what players actually got back across every game we saw, not a figure the operator supplied.

Observed return is uncorrected. These feeds are the operators' own marketing surfaces and the selection leans toward winning rounds, so the figure is biased upward by an amount we cannot measure and that differs between operators. Where it exceeds 100% we label the feed curated, because no game returns more than it takes. Rolling 7 days. A return figure appears once an operator passes 1,000 observed bets, because below that the average is decided by whichever rare large win happened to land in the window. The range after each figure is the 95% interval. These feeds are rolling windows the operators publish themselves, so this is a sample of their play and not all of it.

Observed return, game by game

What players actually got back on the games we saw most, next to what the operator says the game returns. The second column is only filled where an operator publishes a house edge at all.

Rolling 7 days, ordered by how much play we captured. Observed return is uncorrected for feed selection and biased upward by an unknown amount, so treat a single game's figure as a reading of the feed rather than a measurement of the game. The same play grouped by studio reaches a statable figure much sooner, because a proportion converges faster than a heavy-tailed mean. Every game as JSON.

What we can attribute on chain

Money moving inside the games is public at every casino we read. Money moving out to players is private at all of them, so payout figures have to come from the chain, and that means knowing which addresses belong to whom.
