By the dealer's hand going over 21 (a "bust"). Here are the fundamental rules and card values: By getting a "Blackjack" (a two-card hand of 21) when the dealer does not. By getting a hand value higher than the dealer's hand, without going over 21.

The famous "maze-like" layouts are also intentional. By removing any external time cues, casinos create a sense of timelessness, a world where the only thing that matters is the next spin or the next hand. One of the most well-known layout choices is the absence of clocks and windows. The lighting is often kept at a constant, subdued level, mimicking a perpetual twilight that is neither jarringly bright nor sleep-inducingly dark.

Mental Concept
How it's Used in a Casino


Skinnerian Reinforcement
Casinos use a "variable-ratio reinforcement schedule." Rewards (wins) are unpredictable, which is highly addictive and encourages repeated behavior casino (playing). The "Near Miss" Effect
A slot machine may pay out 20 cents on a $1 bet. Free drinks, meals, show tickets, or hotel rooms make players feel valued and rewarded. 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. 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. Psychologically, receiving these perks can make a player feel as though they are "getting something back" for their money, which can mitigate the sting of losses. 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. The more you play, the more you are "rewarded," creating a compelling cycle that is difficult to break. The Monte Carlo 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. Rewarding Continued Play
Complimentary items, or "comps," are another powerful psychological tool. It creates a sense of obligation or casino reciprocity, encouraging them to stay and play longer.
