Slot is a specialized form of the render scope that allows a component to delegate a subset of its rendering logic. The use case for slot is to encapsulate reusable function calls that need to be run when the component is rendered, but do not need to be executed by every child component. This is analogous to the FancyList> use case we covered in Render Scope.

Many players have superstitions about how to win at slots, such as hitting a button at specific times or rubbing machines in certain ways. While it’s tempting to believe that a machine is “due” to pay out, the fact is that results at slot games are completely random. Only spins that match a winning combination receive a payout, and there is no way to predict when that will happen.

Typically, a slot machine is operated by inserting cash or, in “ticket-in, ticket-out” machines, a paper ticket with a barcode into a designated slot. The machine then activates a reel or set of reels to display symbols. A player can then press a button (either physical or on a touchscreen) to initiate a spin, and if the machine matches a winning combination, awards credits based on the paytable. Symbols vary widely depending on the machine, but classics include fruit, bells and stylized lucky sevens. Bonus rounds on some slot machines may offer a different kind of game play, such as picking items to reveal prizes or competing in a mini-game.
