The idea of intermittent reinforcement is a major contributor to slots' addictive qualities. This phenomenon happens when rewards are distributed in an unpredictable way, generating rummy welthanticipation & excitement. Slot machines provide irregular payouts, which keep players interested & waiting for the next big win, in contrast to games like poker or blackjack that have predictable results. Addiction is likely to result from sensory stimulation. The immersive experience that slot machines are made to provide only serves to increase their allure.
