In a casino, a slot machine is a gambling device that accepts cash or, in “ticket-in, ticket-out” machines, a barcoded paper ticket with a unique serial number. The machine then activates a series of reels that display symbols, and, if the player’s bet matches a winning combination, pays out the prize. The machine may also include a bonus event, such as a spin of a bonus wheel or a pick’em game.

A specialized table slot, the periodic slot is used to hold data that repeats over a given period. For example, the rate of evaporation in a reservoir is the same every year. A periodic slot can also handle irregular timeseries, and can have either text or numeric column headings.

When the Compress Repeated Values compression mode is selected, editing of any repeated values will edit any compressed cells. This is because the display precision of the repeated numbers will be used to determine if two numbers appear to be the same; they must be within convergence of each other in order to be considered the same.

When a slot is configured with a custom unit scheme, its reference value will not be adjusted when the units are changed. However, a slot with a default unit can have its reference value changed by selecting the Compress Reference Values option from the Format Slot menu.
