What Is a Slot?


A narrow notch or opening, such as a keyway in machinery or a slit for a coin in a vending machine. Also: a position in a series or sequence; a time slot in a program or schedule.

A slot in hockey refers to a specific area of the rink where wingers and centers have an advantage over defensemen by having a straight-on view of the net when shooting. The area in front of the goaltender and between the face-off circles is known as the low slot. The area in the center of the ice above the face-off circles is called the high slot.

Online casino slots are available in a variety of themes and reel arrangements, and many feature special symbols, bonus rounds, free spins, and other features that appeal to players’ desires. The rules and payouts for different slots can vary considerably, so it is important to read the game info section thoroughly before playing. Some slots offer progressive jackpots and other special prizes.

Slots are normal member functions when called directly, but they can be invoked from any class via a signal-slot connection. This is useful for passing data between the parent scope and a child component, for example when creating widgets that need to know what context they are being rendered in. Using a slot with a context object like this is also useful for ensuring that private slots don’t have access to state from the child scope.
