This act paved the way for the creation of Las Vegas as the world's gambling capital. The American Frontier and the Rise of Las Vegas
Across the Atlantic, America's relationship with gambling was growing on a different trajectory. In the 19th century, saloons in the Wild West were the epicenters of poker. These were often raw and dangerous places, a far cry from their European counterparts. It wasn't until 1931 that the state of Nevada took a revolutionary step by legalizing casino gambling to counter the economic devastation of the Great Depression.

Skinnerian Reinforcement
Casinos use a "variable-ratio reinforcement schedule." Rewards (wins) are unpredictable, which is highly addictive and casino (lowest price) encourages repeated behavior (playing). The "Near Miss" Effect
A slot machine may pay out 20 cents on a $1 bet. The Gambler's Fallacy
A player believes that if a certain outcome (e.g., "red" on roulette) has occurred frequently, the opposite outcome ("black") is "due." In reality, each spin is an independent event. The Role of Comps and Loyalty Programs
Complimentary items, casino or "comps," are another powerful psychological tool. Free drinks, meals, show tickets, casino or hotel rooms make players feel valued and rewarded. Illusion of Control
Allowing players to perform actions—like pulling a lever, throwing dice, or choosing their numbers—creates a false sense of control over a random outcome. The machine still celebrates with lights and sounds, making the player feel like they won, even though they experienced a net loss of 80 cents. Loyalty cards that track a player's spending are a direct application of this, gamifying the act of gambling itself by offering tiered rewards and status levels. It creates a sense of obligation or reciprocity, encouraging them to stay and play longer. The more you play, the more you are "rewarded," creating a compelling cycle that is hard to break. Psychologically, receiving these perks can make a player feel as though they are "getting something back" for their money, which can lessen the sting of losses.

If a game has a 4% house edge, its RTP is 96%. This means that, over a very long period, the game is programmed to return 96% of all wagered money to players. A high-volatility game (like many progressive jackpot slots) pays out infrequently, but the wins can be massive. It allows for longer play sessions but offers smaller jackpots. Understanding the interplay between the house edge, RTP, and volatility allows a player to pick a game that aligns with their goals and casino - lowest price, risk tolerance.
