Almost nothing in a modern casino is more carefully engineered to make gambling more seductive than its slot machines. From the layout of tables to patterns on carpet and lighting, casinos spend enormous effort ensuring that their slot machines draw people in and keep them spending.

In the early days of slot machines, players yanked levers and either cherries or lucky 7s lined up to win some money, or they got nothing at all. By the 2000s, better computer technology allowed casinos to offer much more exciting games and precise control over odds. It also made it possible to develop machines that are solitary, fast and uninterrupted, which is why they have become so addictive.

For decades, it has been assumed that the near-miss events on a slot machine trigger the same type of conditional reinforcement as a real-world gamble. However, experimental evidence has been inconsistent. One problem is that a few studies have used extinction as a treatment, which renders it impossible to determine whether or not near-misses actually reinforce gambling persistence.
