**Powerball numbers are drawn from two sets of numbers, so the odds of winning a prize are calculated by combining the odds for both sets of numbers for all prize levels. The odds for matching just the Powerball are calculated by combining the odds of selecting the Powerball and the odds of not selecting any of the five numbers from the first set of numbers drawn.**

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.

Ohio and New York joined The Big Game consortium on May 15, 2002, when the game was renamed The Big Game Mega Millions, temporarily retaining the old name and the original "gold ball" logo. The "Big Money Ball" became the "Mega Ball." While the game's name was altered, the yellow ball in the new Mega Millions logo continued to read "The Big Game" until February 2003, after which it was replaced with six stars representing the original members of the consortium. The first (The Big Game) Mega Millions drawing was held two days later, on May 17. The Mega Millions trademark is owned by the Illinois Lottery. The first three lotteries to join Mega Millions were Washington (in September 2002), Texas (in 2003) and California (in 2005); California was the last addition to Mega Millions before the cross-sell expansion of 2010. Montana joined Mega Millions on March 1, 2010, the first addition to Mega Millions after the cross-sell expansion.

Sure, the odds of matching 1 red ball out of 35 are 1 in 35, but we are not giving the odds for matching a red ball. We give the odds for winning a prize for matching one red ball ALONE. If you match the red ball plus at least one white ball, you win some other prize, but not this prize. The odds of matching one red ball ALONE are harder than 1 in 35 because there is some risk that you will also match one or more white ball numbers - and then win a different prize.**

*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.*

`Rules vary according to the applicable laws and regulations in the jurisdiction where the ticket is sold, and the winner's residence (e.g. if a New Jerseyan wins on a ticket bought near their workplace in Manhattan). Mega Millions winnings are exempt from state income tax in California; while Florida, New Hampshire, South Dakota, Tennessee, Texas, Washington state, and Wyoming do not have an income tax. On the other hand, some residents of New York City and Yonkers, New York pay three levels of income tax, as these cities levy income taxes.`

__Two identical machines are used for each drawing, randomly selected from four sets. The model of machine used is the Halogen, manufactured by Smartplay International of Edgewater Park, New Jersey. There are eight ball sets (four of each color); one set of each color is randomly selected before a drawing. The balls are mixed by a turntable at the bottom of the machine that propels the balls around the chamber. When the machine selects a ball, the turntable slows to catch it, sends it up the shaft, and then down the rail to the display.__

_{Once your ticket is purchased, scanned and uploaded into your account that ticket is yours. Legally and in every other sense possible. The same questions always pop up at this stage of the explanation to new time online lottery players and these doubts can be best explained in further detail in the article on the Iraqi Lottery winner but the gist of it is as follows: }

Due to falling sales of Hot Lotto (whose final drawing was October 28, 2017), a new version of Lotto America became available on November 12, 2017; its first drawing was November 15, 2017. Lotto America is available wherever Hot Lotto was offered at the time of its final drawing (except New Hampshire.) Lotto America is drawn on Wednesday and Saturday nights after 11 p.m. ET/10 p.m. CT. For each $1 play, bettors choose five numbers from 1 through 52, and a "star ball" numbered from 1 through 10, or ask for terminal-generated numbers. For an additional $1 per play, the bettor can add the "All-Star Bonus" option, which multiplies non-jackpot prizes by 2, 3, 4, or 5.[1][2][3][4] The minimum Lotto America jackpot is $2 million; however, the game's initial jackpot was $15 million; the 13 members chose to augment the jackpot with funds from Hot Lotto, whose final jackpot was not won.

Based on statistical projections, the average jackpot win increased from $95 million to $141 million. Over 3.5 million additional prizes were expected to be won yearly due to the change in probability. The starting jackpot increased to $20 million, with minimum rollovers of $5 million. The jackpot contribution increased from 30.3% to 32.5% of total sales. The Power Play option was modified; second prize, usually $200,000, was given an automatic 5x multiplier, making the 5+0 prize $1 million cash. The bonus second prize if the jackpot exceeded its previous record by $25 million, triggered only twice, was eliminated with the 2012 format change.

If you’re not using an official state lottery website, the retailer may not be licensed and therefore could have no connection to the state lottery programs. Last year, during the record-breaking $1.6 billion Powerball jackpot, Holyfield says Michigan’s lottery office fielded several calls from consumers who purchased tickets online, only to have the vendor shut down without notice.

^{Unlike Hot Lotto, which used a random number generator during most of its run (including the December 2010 drawing whose jackpot was "won" by Eddie Tipton, a MUSL employee), Lotto America is drawn using physical ball machines and numbered balls. One machine draws the five main numbers while another is used to draw the "Star Ball". As of September 1, 2018, none of these drawings have been made available to the viewing public; these drawings are believed to be held in Tallahassee, Florida, even though Florida does not participate in the game.[5] }

The only way to be sure that what you are buying is “official” is to purchase your tickets from a company that has agents that will purchase in the real world the Powerball tickets online that you have selected. If you are a more trustworthy person and don’t need a scanned copy of your Powerball tickets online then by all means go for an online lottery ticket provider that follows the insurance model.
