When a player wins the Lotto America jackpot, the winner may choose to receive the prize in annuity payments or may elect to take a lump-sum payment. A player has 60 days from the date they claim their prize to choose the "cash" option or the "annuity" option. If the player selects the "cash" option, the prize will be a single cash payment equal to the amount available to the lottery for the jackpot prize pool. The "cash" prize is estimated to be approximately one-half of the estimated jackpot, depending on current interest rates. If the player chooses an annuity, it will be paid in 30 payments over 29 years, and the annual payment will be increased by a rate as determined by lottery officials. If the cost to purchase the annuity is less than $250,000, the lottery may elect to pay the prize as "cash."
Michael Sweeney, executive director of the Massachusetts State Lottery, apologized Thursday afternoon for the mix-up, saying it was the result of a “human error” but added that the lottery’s internal systems always had the correct information. He said those internal systems ran a routine report in the morning identifying Chicopee as the correct location, and lottery officials then checked to ensure that it was accurate.
Every jurisdiction has its own law on winners remaining anonymous. Some jurisdictions are required by law to provide the winner's name, city of residence, game won and prize amount to any third party that requests the information. Other jurisdictions allow winners to create trusts to shield their names from the public, or otherwise claim prizes anonymously. Check with your lottery to see if taking a photo of the winner is required and what its rules are on prize claims. Even if you keep your identity secret from the media and the public, you will have to be known to the lottery so officials can confirm you are eligible to play and win, as well as other legal requirements.

A Powerball jackpot winner may choose to receive their prize in 30 payments over 29 years or a lump-sum payment. The cash value option, in general, is the amount of money required to be in the jackpot prize pool, on the day of the drawing, to fund the estimated jackpot annuity prize. The advertised jackpot annuity and cash value are estimates until ticket sales are final, and for the annuity, until the Multi-State Lottery Association takes bids on the purchase of securities. 
Other winners in excess of $250 million: On December 25, 2002, Jack Whittaker, president of a construction firm in Putnam County, West Virginia, won $314.9 million ($428 million today), then a new record for a single ticket in an American lottery. Whittaker chose the cash option of $170 million, receiving approximately $83 million after West Virginia and Federal withholdings.[35]

Two machines are used in each Mega Millions drawing. The model used for Mega Millions is the Criterion II, manufactured by Smartplay International of Edgewater Park, New Jersey. The balls are moved around by means of counter-rotating arms which randomly mix the balls. Individually, the five white balls, several seconds apart, drop through a hole in the bottom of the mixing drum.
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!
