Why Math Matters at the Casino
Every casino game has a built-in house edge — a mathematical advantage for the house. Understanding these numbers is the first step toward making informed decisions. Blackjack is unique because skilled play can reduce the house edge below 0.5%, and card counting can shift it in the player's favor.
