Lottery is a system of distribution of prizes by chance, usually by drawing names from a pool of entrants. Prizes can be money or goods. In some cases, the amount of the prize is proportional to the number of tickets purchased. Lotteries are most commonly run by governments or licensed promoters, but they may also be privately organized. Some private lotteries offer games of skill, while others are pure chance.
