The slot> element, part of the Web Components technology suite, is a placeholder inside a component that you can fill with custom markup to create a custom view. Unlike render functions, slots do not have access to state in the parent scope; instead, they encapsulate reusable logic and pass their own props (via an expression) to the child component to be rendered.

To use a slot, simply place the v-slot directive within your markup. Its shorthand, template v-slot:header> can be replaced by template head -> header>. Likewise, the child component can pass its own props to a slot by including them in the v-slot’s expression as if they were its own directive argument.

A special feature of slot games that pays out credits based on the number of symbols matched on the reels. Typical bonus features include free spins, extra reels, and interactive mini-games. Bonus rounds may also have a specific theme that reflects the overall design of the machine, or they might be tied to a specific player behavior that has been observed by casino personnel.
