VLT is a gaming machine that allows gamblers to bet on the outcome of a video game.
A VLT is similar to a slot machine, in that each terminal is a stand-alone device containing a random-number generator. Each terminal is connected to a centralized computer system that allows the lottery jurisdiction to monitor game play 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.
A video lottery terminal at a minimum will utilize randomness in determination of prizes, contain some form of activation to initiate the selection process, and make use of a methodology for delivery of the determined outcome. Each video lottery terminal is connected to a centralized computer system that allows the lottery jurisdiction to monitor game play and perform control functions.
