What is a Slot?

A narrow notch or groove, as in the keyway in a lock, or a slit for a coin in a vending machine. Also, a position in a group, series, or sequence. He got his hair cut in the 2 p.m. slot.

Charles Fey’s invention of a slot machine in 1887 was a revolution compared to the earlier Sittman and Pitt machines. His new slots allowed automatic payouts and had three reels. Instead of poker symbols, Fey used spades, horseshoes, hearts, and Liberty bells – three aligned Liberty bells were the highest winning combination. This allowed a much larger number of combinations, increasing jackpot sizes.

Modern slot machines use microprocessors that assign different probabilities to each symbol on each reel. This means that a single symbol may appear on every spin, whereas another symbol might only appear once per reel. This is why, when a player sees someone else’s winning combination, he or she may believe that it was “so close”. In reality, however, the probability of hitting a specific symbol on a specific reel is incredibly small.

If you play the slots for long enough, you will probably lose money. But if you are careful and don’t get greedy, the experience can be fun. Getting too greedy and betting more than you can afford to lose are the two biggest pitfalls that can turn a slot machine into a nightmare. These examples are from the Merriam-Webster Online Dictionary.
