    Depends on whether you mean the jackpot or just win a prize? If you play the Spanish Christmas Lottery you have a 10% chance of winning, so buy 5 tickets and you have a 50% chance to win. The catch? Tickets cost 200 Euro! (you can also buy them in 10% portions)

          That all depends on the game played.
