Slot is a narrow notch, groove or opening, as a keyway in a machine or a slit for coins in a vending machine. It is also a term for a position, such as the area in front of the goaltender and between face-off circles on an ice hockey rink, or a site within a computer in which an add-on card can be installed.

A slot is also a device in a video game that randomly displays a set of symbols and pays credits if they line up with a winning combination. It can be activated by pressing a button or lever, either physical or on a touchscreen, and the symbols vary depending on the theme of the machine. Classic symbols include fruits, bells and stylized lucky sevens. Many slot games have a specific theme and bonus features aligned with it.

During the slot game development process, it is important to define the main characteristics of your product. This includes the target audience, themes and features, language support, platform considerations (e.g. 2D or 3D) and if you need to develop the game for multiple devices. At this stage, artists should produce sketches, wireframes and mockups that display how your slot game will look. It is also important to define the slot’s volatility and risk of loss, as well as its payout frequency and amounts. This information will be used to create the graphics and mechanics of your slot game.
