A slot is a narrow opening, especially one for receiving something, such as coins or letters. The word is also used to refer to a position in a series or sequence, such as a job or an appointment.

These symbols may vary from traditional fruit symbols to stylized lucky sevens, and many slots have themes that are based on popular culture or historical events.

Progressive jackpots can reach millions of dollars, making them some of the most popular casino games.
