When flying, you check in early, make it through security, wait for your turn at the gate, struggle with the overhead lockers and finally get on board. But then the captain says, “We’re waiting for a slot.” What is a slot and why can’t you take off as soon as you are ready?

A slot is a position or time in a series or sequence. It may also refer to:

A machine that accepts cash or tickets with a cash value called TITO (ticket in, ticket out). Some people pump money into two or more machines at a time, but if a casino is crowded, it is wise to limit yourself to one machine. Too many can make it hard to keep an eye on your total, and you’ll likely end up in a situation like the woman who was dropping coins into machine number six while number one on the aisle paid out a big jackpot — even though the random-number generator was operating continuously between signals from the button or handle.

It’s also important to play only the types of slots you enjoy, because luck plays a major role in the games. The best way to maximize your enjoyment is to pick the machines that match your preferences: for example, you might prefer simpler machines with a single payline or ones that have more bonus features. But always remember to set a budget in advance and stay within it. It’s no fun to lose money you didn’t plan on spending.
