Lottery is a game of chance in which numbered tickets are sold and prizes (usually cash) are awarded to the winners, usually via a random drawing.

It will also provide tips for playing a lottery and advice for choosing a winning strategy.

Lotteries have long been a popular form of gambling. The first recorded lotteries were keno slips in China during the Han dynasty (205–187 BC). In Europe, early lotteries raised funds for town fortifications and to help the poor, and they may have been the inspiration for modern state-sponsored games.
The basic requirements of all lotteries are a pool or collection of tickets and their counterfoils, some way to record the names of bettors and their stakes, and a procedure for selecting winners. This procedure is sometimes called the drawing or shuffling, and it must ensure that the selection is truly random. Traditionally, this has been done by mixing or shaking the tickets, but more recently computer programs have been employed.
A third requirement is some way to divide the pool between costs and profits for the organizers and the winners. The costs of organizing and promoting the lotteries are normally deducted from the pool, as are some percentages of the total prize money. The remainder available to bettors is often decided by a ratio between few large prizes and many smaller ones. This decision can have a significant impact on ticket sales, since potential bettors are generally attracted to the idea of very large prizes but are less interested in the prospect of frequent and small wins.
