There are different kinds of lottery games, each with its own rules and prizes. The winner of a lottery can choose between annuity payments and a one-time payment. If the lottery is a fixed prize fund, the prize amount is determined in advance. These prizes can be cash, goods or services.

Other lotteries are based on chance. The player has a chance of winning, but the odds are largely random. Usually, a jackpot is advertised, but if the person buys a ticket, there is no guarantee they will win. The winner can expect to take home around one-third of the advertised jackpot.
