How we calculate this
Every figure is compared with what fair dice give: how often three of a kind lands, how often each face shows, and, where the game has them, what the even-money bets return. Each check has a 95% range and is judged with every other check on the monitor by the same rules.
Every check gets a two-sided p-value. Because 177 checks run on this monitor at once, the p-values are corrected with the Holm method before a result counts as not consistent (corrected p below 0.01). A result with an uncorrected p below 0.01 is shown as borderline. These thresholds are set in advance and are the same for every game. Full method.
Three dice per round. With fair dice, three of a kind comes up in 1 round in 36 (2.78%), each face on 1 die in 6, and Big and Small each win 105 rounds in 216, which makes both even-money bets return 97.22%.
