Crypto jackpot games: how the pot and odds work

A crypto jackpot is a player-vs-player game where everyone adds stakes to one shared pot and a single winner takes it. Your chance of winning equals your share of the pot: add 20% of the money and you hold 20% of the tickets. When the round ends, a provably fair draw picks one ticket, and its owner receives the pot minus any fee.
