The odds of winning the Mega Millions jackpot are 1 in 302.6 million, making them the highest odds of any other state or multi-state lottery game ever played in the United States. However, this means the jackpot can grow to surpass the billion-dollar mark with relative ease. The overall odds of winning any prize are 1 in 24, which is slightly better than that of Powerball, which are 1 in 24.87.
The largest jackpot in Mega Millions history was $656 million annuity value (with a cash option of $474 million) for the March 30, 2012 drawing, in which there were three jackpot-winning tickets; one each in Illinois, Kansas, and Maryland. All three tickets had been claimed by April 18, with each set of winners choosing the cash option of $158 million.
Even though some scratch cards costing as much as $50 in Texas and $30 in Massachusetts, state lotteries are exempt from Federal Trade Commission “truth in advertising laws” The Federal Communications Commission prohibits the broadcast of lottery advertisements, but has exemptions for lotteries “conducted by a state acting under the authority of state law. Hence, TV commercials like “The Possibilities are Endless.” (Lotteries raise over $70 billion a year, according to the North American Association of State and Provincial Lotteries. Profits from the Powerball are used to fund public projects approved by state legislatures.)
