The odds of winning the main lottery jackpot depend on the lottery game being played. For example, the odds of winning the Powerball jackpot are 1 in 292 million and the Canada Daily Grand is 1 in 13.45 million. There are millions of possible number combinations that can win, which means that the more unique tickets you purchase, the higher your chances are of winning. Even if you don’t win the jackpot, you may win something.
