Lottery

Pick 6 numbers from 49; 6 are drawn by an unbiased Fisher-Yates shuffle. Match 2 or more and the ticket pays.

A real lottery keeps something like half of every ticket. This one does not, because the paytable is derived rather than written down: pays rise geometrically from the lowest paying hit count, then the whole row is scaled so the exact hypergeometric expectation lands on 99%.

RTP exactly 99.00%, recomputed from the rounded multipliers actually paid.
