Lottery is a type of gambling in which numbered tickets are sold and prizes are awarded to those whose numbers are drawn by chance. It is often used to raise money for charitable projects and can be played by individuals, private companies or even governments. The first recorded lottery was held in the Low Countries in the 15th century to raise funds for town fortifications and to help poor people.
Whether the game is conducted by state, private, or commercial entities, the basic elements of any lottery must be the same. First, there must be some way to record the identities of bettor, the amounts staked, and the numbers or symbols selected by each. Then the tickets must be thoroughly mixed by some mechanical means, usually shaking or tossing. Lastly, there must be some method of extracting the winning tokens from this pool. This procedure may be carried out by hand, but computers are increasingly employed for this purpose.
Many critics of lotteries argue that their advertising is deceptive and misleading, promoting unrealistic expectations about winning (e.g., the amount of money that can be won is actually paid in annual installments over 20 years, with inflation and taxes dramatically eroding the current value); fostering unhealthy compulsive gambling; generating substantial tax revenues while reducing overall state government spending; and working at cross-purposes with other public policy goals. Others note that a lottery is a classic example of public policy made piecemeal and incrementally, with little or no broader overview.
