Slot machines are not programmed to pay out at specific times; rather, they operate based on a random number generator (RNG) that ensures each spin is independent and random. This means that payouts are determined by chance rather than being set to trigger at particular intervals or moments. While casinos may configure the overall return-to-player (RTP) percentage for a machine, which dictates the average return over a long period, individual outcomes remain unpredictable. The perception that machines "pay out" at certain times often arises from cognitive biases and misinterpretation of random events, where players might believe patterns exist due to their experiences.
