The world's largest jackpot was a $656 million Mega Millions jackpot in March 2012.
If you win a prize in the course of one of the drawings, you do not have to wait until the last drawing has occurred just before collecting those winnings.
Pick a game, any game, and there are thousands — no millions — of persons who commit their really hard-earned dollars on a $2 piece of a paper that a lot more generally than not becomes a disappointment.
