A video lottery terminal (VLT), also sometimes known as a video gaming terminal (VGT), video slots, or the video lottery, is a type of electronic gambling machine. They are typically operated by a region's lottery, and situated at licensed establishments such as bars and restaurants.

VLTs typically feature a selection of multiple games, primarily video slot machines and Keno. Their exact operation depends on local law: many VLTs are stand-alone devices containing a random number generator. Each terminal is connected to a centralized computer system that allows the lottery jurisdiction to monitor gameplay and collect its share of revenue. The outcome of each wager on a VLT is random. VLT operators are not able to program the total amount wagered, or payouts, through the central computer system. A minimum percentage payout usually is written into that jurisdiction's law. That percentage is realized not by manipulation of the game, but by adjusting the expected overall payout.

In some jurisdictions, VLTs do not contain a random number generator, and display results from a fixed pool controlled by the central system (in similar fashion to scratch-off lottery tickets).
