Before the agreement, the only places that sold both Mega Millions and Powerball tickets were retailers straddling a border; one retailer on the Sharon, Pennsylvania/Masury, Ohio border sold both Mega Millions (via the Ohio Lottery) and Powerball (Pennsylvania) before the agreement and continued to be the only retailer to sell tickets for both lotteries.[12]
Some retailers that sit on state lines often offer both state lotteries with state boundaries clearly marked, since such sales still have to occur in the physical state it is offered. One retailer located along U.S. Route 62that is largely in Sharon, Pennsylvania but has a small portion lying inMasury, Ohio sells both the Ohio Lottery and the Pennsylvania Lotteryat one location. The first modern US joint-state lottery game was formed in 1985 inMaine, New Hampshire, and Vermont. In 1988, the Multi-State Lottery Association (MUSL) was formed with Iowa, Kansas, Missouri, Oregon,Rhode Island, West Virginia, and the District of Columbia as its charter members; it is best known for Powerball, which was designed to create large jackpots. Another joint lottery, The Big Game (now called Mega Millions), was formed in 1996 by six other lotteries as its charter members.

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]

The probability and odds can be taken into a mathematical perspective: The probability of winning the jackpot (through October 27, 2017) was 1:(75C5) x (15); that is: 75 ways for the first white ball times 74 ways for the second times 73 for the third times 72 for the fourth times 71 for the last white ball divided by 5 x 4 x 3 x 2 x 1, or 5!, and this number is then multiplied by 15 (15 possible numbers for the "Megaball"). Therefore, (75 x 74 x 73 x 72 x 71)/ (5 x 4 x 3 x 2 x 1) x 15 = 258,890,850, which means any combination of five white balls plus the Megaball has a 1:258,890,850 chance of winning the jackpot. Similarly, the odds for second prize are 1:(75C5) x (15/14) = 1: 18,492,204 chance of winning. The overall probability of winning any prize was 1 in 14.7. If there are no jackpot winners for a specific drawing, the jackpot will keep increasing, however, the odds will still remain the same.

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!
