“There’s no such thing as a hot machine or cold machine-it’s all variance,” says Andrews, who is also the cofounder of Unabated, which sells tools and resources to sports bettors. So while the machine is theoretically paying out more money, the odds are always in the house’s favor. By regulation, a Nevada casino must have a theoretical payout of at least 75%-meaning for every $1 wagered, a player can expect to make back at least 75 cents on average-but the average rate is closer to the low 90% range. While slots have some of the best odds in a casino, sharp gamblers understand that the pay rate for them means very little.
