In 2005, Mega Millions was the target of a mailing scam. A letter bearing the Mega Millions logo was used in a string of lottery scams designed to trick people into providing personal financial information by cashing bogus checks. The letter, which had been sent to people in several states via standard mail, included a check for what the scammers said was an unclaimed Mega Millions prize. If the check was cashed, it bounced, but not before the bank stamped it with a routing number and personal account information and sent it back to the fraudulent organization, providing them with the recipients' financial information.[42]
To play Lotto America, pick five main numbers between 1 and 52 and one Star Ball from a separate pool of 1 to 10. You can choose your own numbers or ask for a Quick Pick.

These changes were made to increase the frequency of nine-figure jackpots; a Powerball spokesperson believed a $500 million jackpot was feasible (it became a reality within the year,[15]) and that the 1st $1 billion jackpot in US history would occur by 2012[16] Less than three months after the Powerball changes, Mega Millions' jackpot reached $656,000,000 despite remaining a $1-per-play game.[17] The random Power Play multiplier was retired for a set, fixed dollar amount payout.[18] The $25 million rollover "cap" (creating larger 5+0 prizes) was eliminated.

The structure of the draw is one which regular lottery players will be very familiar with; players must pick 5 regular numbers from a pool with a total of 69 numbers and in addition to these regular number picks, you also choose one bonus ball (known as the Powerball) from a pool of 26. These two pools of numbers are mutually exclusive and remain completely separate throughout the drawing procedure. In order to jackpot the US Powerball, you need to match all 5 regular numbers and the Powerball. Do this and you are instant Powerball millionaire – it’s as simple as that!
