^ Jump up to: a b If more than one play wins the jackpot in a given drawing, the prize is divided equally among 5+1 plays. Winners have one year to collect a jackpot share; for other prizes, the deadline also is one year, except in California, where it is 180 days. Other than in and Texas (see below), a jackpot winner has 60 days from either the drawing, or in some jurisdictions, after claiming, to choose cash or annuity. The relative value of actual cash jackpot share fluctuates. Jackpots began at $15 million (disbursed in 30 graduated annual payments if the annuity is chosen); the corresponding cash value fluctuates depending on interest rates.
On March 13, 2010, New Jersey became the first Mega Millions participant (just before the cross-sell expansion) to produce a jackpot-winning ticket for Powerball after joining that game. The ticket was worth over $211 million annuity (the cash option was chosen). On May 28, 2010, North Carolina became the first Powerball member (just before the cross-selling expansion) to produce a jackpot-winning Mega Millions ticket after joining Mega Millions, with an annuity jackpot of $12 million.

The advertised estimated jackpot represents the total payments that would be paid to jackpot winner(s) should they accept the annuity option. This estimate is based on the funds accumulated in the jackpot pool rolled over from prior drawings, expected sales for the next drawing, and market interest rates for the securities that would be used to fund the annuity.[2] The estimated jackpot usually is 32.5% of the (non-Power Play) revenue of each base ($1) play, submitted by game members to accumulate into a prize pool to fund the jackpot. If the jackpot is not won in a particular drawing, the prize pool carries over to the next drawing, accumulating until there is a jackpot winner. This prize pool is the cash that is paid to a jackpot winner if they choose cash. If the winner chooses the annuity, current market rates are used to calculate the graduated payment schedule and the initial installment is paid. The remaining funds in the prize pool are invested to generate the income required to fund the remaining installments. If there are multiple jackpot winners for a drawing, the jackpot prize pool is divided equally for all such plays.
Reflecting common practice among American lotteries, the jackpot is advertised as a nominal value of annual installments. A cash value option (the usual choice), when chosen by a jackpot winner, pays the approximate present value of the installments. Mega Millions' previous format began on October 19, 2013; its first drawing was three days later. The current version of Mega Millions uses a 5/70 (for the white balls) plus 1/25 (for the "Mega Ball") double matrix to select its winning numbers.

The American Powerball originally started life way back in 1988 and was known as "Lotto America". In 1992 this became the Powerball lottery, with the first official Powerball draw being held on April 19th, 1992. The game has grown and evolved over the years with new States joining (now totalling 44 States) and various changes being applied to the ball and prize structure. These include a change in the annuity prize payments from 20 yearly payments to 30, and the addition of a cash option for the jackpot. In addition, players are now able to purchase their Powerball lotto tickets online.

Mega Millions (which began as The Big Game in 1996 and renamed, temporarily, to The Big Game Mega Millions six years later) is an American multi-jurisdictional lottery game; it is offered in 44 states, the District of Columbia, and the U.S. Virgin Islands. The first (The Big Game) Mega Millions drawing was in 2002; see below. (What is now Mega Millions initially was offered in six states; the logo for all versions of the game following the retiring of The Big Game name featured a gold-colored ball with six stars to represent the game's initial membership.)
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!
