Grimoire vs Jack and pot
Side by side: what each studio publishes about its game, and what the sampled bet feeds showed over 30 days. Observed figures are past results of a sample and say nothing about the next spin.

What this page isand what it is not
Grimoire and Jack and pot side by side: the facts each studio publishes about its game, and what the public bet feeds of the tracked casinos showed on it over the last 30 days. The studio rows are read from the studios’ own sites; a dash means the studio does not list the figure. The observed rows are sums over the sampled bets, so a game played on more casinos we read has a bigger sample, and the 95% band says how much the observed RTP could move on a sample that size.
None of it is a recommendation. A higher observed RTP over 30 days is what happened in that sample; every spin is independent, and no past figure changes the odds of the next one.
