Share of all recorded rounds that reached each multiplier (dots) against the formula (dashed line), both axes logarithmic. A game that follows it keeps the dots on the line.

How we calculate this

Each round ends at one multiplier. For a cash-out at a target, the return is the target times the share of rounds that reached it. We compare that share with what the operator's own formula (Gamdom verifier: 1 in 100 rounds at 1.00x, else floor((e - h/50) / (e - h) x 100) / 100) predicts, give a 95% range for every figure, and mark targets with too few rounds as insufficient instead of showing a number we can't stand behind. Targets from 20x to 100x appear by themselves once enough rounds have reached them. The implied return uses every round at once: under the formula, the share of rounds that end at 1.00x fixes the return at every target.

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.

Gamdom lists a 99% RTP. Under its own formula only a cash-out at 1.01x comes close (98.98%); a 2x cash-out returns 98% and 10x 97.2%, which is what the rows above measure.

Formula: Gamdom verifier: 1 in 100 rounds at 1.00x, else floor((e - h/50) / (e - h) x 100) / 100.
