The most common types of lotteries are American, British and Canadian. In America, lotteries are run by state governments and private companies. Prizes range from small amounts of money to large cash prizes. The British lottery is run by the National Lottery, which was established in 1994. The lottery has two main draws: the main draw consists of national lottery games while the supplementary draw consists of ‘Lucky Dip’ games that allow people to buy a ticket for a chance to win a larger amount of money. The Canadian lottery was launched in 1976. Prizes can range from a few hundred dollars to millions of dollars. Lotteries are often criticized for encouraging gambling addiction and for being unfair to those who don’t win the jackpot because they may have paid high prices for their tickets.
