In computer games, a slot is a container for a piece of data. The size of the slot is determined by its associated data and can vary between different applications. It can be filled or empty and is accessed via a special address. When a slot is empty, it can be filled with new data by the application using special handling. This allows the application to change the data stored in the slot without having to rebuild the entire component.
Casino managers are always under pressure to maximize the all-important slot revenue, but they do not want to kill the golden goose by increasing prices so much that players simply choose another casino. This fear is the reason why many casinos resist increasing house advantages by more than a small percentage. Players can often detect these hidden price increases and react accordingly, either by choosing to play at a more expensive venue or by choosing not to gamble at all.
