Slot machine – a gambling device where players try to line up three or more symbols on the reels. They can be found in bars and taverns as well as in casinos.

Psychologists believe that slot machines trigger feelings of control in their users, despite the fact that they are inherently uncertain. When a player pushes the’spin’ button, the visual whirlwind of colors and shapes in front of their eyes releases Dopamine, a hormone that makes them feel in control.

It’s this desire for control that helps explain why slots have become so popular with gamblers. Despite their reliance on luck, they offer the chance to play multiple winning combinations in quick succession.
