A game where players select a small group of numbers (usually six) from a large set (usually 49) and are awarded prizes based on how many match the randomly drawn result. In a typical lotto game, a player might be asked to select six numbers from a set of 49. At a predetermined time, six numbers are randomly drawn by the lottery people. The player wins a major prize if all six of their numbers match those chosen in the random drawing. The player wins smaller prizes for matching three, four, or five of the drawn numbers. Variants of lotto games include 'Powerball' or 'Power Ball' and 'The Big Game' and 'Lottery Extra' (UK).
