A device, usually mechanical or electrical, that accepts paper tickets with barcodes or coins as payment for credits that can be used to play games of chance. It may also return any winning combinations of symbols according to a paytable. The machine may be activated by pulling a lever or button, or by pressing a touchscreen. The symbols vary according to the machine’s theme, but classics include bells, fruit, stylized lucky sevens, and other icons. The machine may also accept cash or, in “ticket-in, ticket-out” machines, barcoded tickets that are scanned before and after each spin.

A v-slot is a scoped function that encapsulates reusable logic and delegated visual output to a child component using the FancyList> use case. This approach is a more flexible alternative to passing parameters as part of the constructor or creating an entire manual render function, and it allows for more sophisticated UI components. In addition to encapsulating logic, v-slots can be used to limit the number of values that are passed into a function and reduce the scope of variables that need to be tracked.
