When Texas joined Mega Millions in 2003, it began offering an option, initially available only to Texas Lottery players, known as the Megaplier, which was similar to Powerball's Power Play. The 11 Mega Millions lotteries without Megaplier on the January 31, 2010 cross-selling date gradually added the multiplier option; by January 2011, all Mega Millions lotteries, except for California, offered the Megaplier. The Texas Lottery owns the trademark to Megaplier.[8]
Mega Millions players have the option to activate a multiplier, called Megaplier, in 45 of its 46 jurisdictions; it is functionally similar to Powerball's Power Play; except the latter cannot multiply second prize by 5. (Neither Megaplier nor Power Play are offered in California because its state penal code distinguishes between a "lottery" in which the bank cannot be "broken", and a "banked game" whose bank theoretically could be broken; only a "lottery" was authorized by the state Lottery Act.) By adding $1 to a basic Mega Millions game, to $3, a player has an opportunity to multiply any non-jackpot prize by 2, 3, 4, or 5. The Megaplier is drawn by the Texas Lottery (before the cross-sell expansion on January 31, 2010, it was the only lottery to offer Megaplier), which is drawn by a random number generator (RNG). The odds for each Megaplier possibility are not uniform.[19]
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.
In March 2009, it was reported that New Jersey, already a Mega Millions member, sought permission to join Powerball. Shortly after, discussions were revealed about allowing each US lottery to offer both games. On Oct 13, the Mega Millions consortium and MUSL reached an agreement in principle to cross-sell Mega Millions and Powerball.[9] In Nov, MUSL signed an agreement to start streaming Powerball drawings online.[10][11]
The American Powerball lottery makes use of two machines drawing two sets of numbers. In this way, it is similar to other lotteries like the Mega Millions and EuroMillions. Powerball players need to match five numbers from a possible 69 (these are the white numbers), and one number from a possible 26 (these are the red bonus ‘Powerballs’). If a player matches up all six numbers that have been drawn, they will win the jackpot. Second tier division winners have a $1 million prize to look forward to – one does not even need to match all six numbers in order to become a millionaire with the US Powerball game!

For a monthly fee, PlayEuroLotto syndicate betting can boost your chances of winning a serious lottery prize dramatically. In a syndicate betting, lottery players pool their lines for a draw and agree to share any prizes won. If any of those lines wins, then you get to share in the prize money. The more shares you bet with, the larger the share of the prize money you win. Acording to the UK National Lottery, 1 in 4 jackpots is won by a syndicate.
State lotteries have become a significant source of revenue for states, raising $17.6 billion in profits for state budgets in the 2009 fiscal year (FY) with 11 states collecting more revenue from their state lottery than from their state corporate income tax during FY2009. Lottery policies within states can have conflicting goals. Given that instructions are passed down from state legislatures, lottery implementation is often expected to be carried out with reduced advertising and funding while still producing the same amount of revenue. This issue led states to look for loopholes in the system. Massachusetts, for example, had its advertising budget dramatically cut, and therefore started using free-play coupons as money to pay for advertising. This led to an IRS investigation into alleged non-reporting of income because the IRS considered the coupons to have monetary value.
And of course, if non-US residents are eligible to buy the tickets, they are also eligible to claim the prize money should they win. However, be aware that the rules covering taxes and withholding vary depending on where you live. Countries outside of the United States might have different procedures. If you do win, be sure to consult with a tax professional for more information.

*a tip to know whether the website you are looking at actually buys lottery tickets online or follows the insurance model is to check the wording that they use. If you see the words “Play” then you can be confident it is a company that has agents and buys your tickets physically, if you see the words “Bet” you can be sure it is following the insurance model and you are placing a bet on the outcome of a lottery.
