Detective for Wheel Bias
Record of 3,000 spins from wheel wey fit get bias or no get. Use di tools of di Lab to find di hot sector, or announce sey di wheel fair.
Five wheels, five verdicts. Heat map, bar chart with di ±2σ band and chi-square testlabChi-square testStatistical test wey dey compare di hits wey you see for each pocket with di n/37 wey you expect. Dem dey use am to judge whether wheel get bias.Read di whole tin → dey for di table; sector scan dey as hint, but e go cost you one point. One of di wheels fair.
Wheel 1 of 5 · 3,000 spins
How we dey score
9–10: Jagger for want make you dey watch di wheel.
6–8: you fit read heat map and you no go fall for false positive.
3–5: you find di strong ones; di bias wey small and di wheel wey fair na di real test.
Under 3: read How to Find Bias for Roulette Wheel and Size of Di Sample. Three thousand spins just manage reach for strong bias, and e no reach for bias wey small.
Wetin make am hard
For fair wheel with 3,000 spins, di expected count for each pocketequipmentPocketOne of di 37 small boxes wey get number for di rotor. Dem also dey call am: slot, cup.Read di whole tin → na 81 and di standard deviationmathsStandard deviationSquare root of variance; di normal distance between one result and di expected value.Read di whole tin → na about 9, so some pockets go dey outside di ±2σ band just by chance. Pocket wey get bias of +40% dey around 113, about 3.5σ; for +20% e dey around 97, under 2σ, and you no fit see am for one single pocket. SectorswheelSectorPockets wey follow each oda for one arc of di wheel, no be group for di layout.Read di whole tin → dey add up: di 5-pocket scan na how real bias players take find wheels, becos pockets wey dey near each oda dey share di same mechanical fault.
Questions wey pipo dey ask
Becos di hardest skill for bias play no be to find hot sector; na to no find one wey no dey there.
Thousands for strong bias; tens of thousands for bias wey small. Di family of Jagger watch di wheels for weeks.
Small laugh
Find di sector. Or agree sey e no dey.
