Presumably due to their experience with the Power Play option for Powerball, all 23 lotteries joining Mega Millions on January 31, 2010 immediately offered Megaplier to their players. The Megaplier continues to be drawn by Texas Lottery computers, as California does not offer the multiplier. Montana, offering Powerball before the expansion date, became the 24th lottery to offer the Megaplier, followed by Nebraska (the 25th), Oregon (the 26th), Arizona (as the 27th) and Maine (as the 28th lottery to offer the Megaplier option). After Colorado and South Dakota joined Mega Millions, this raised the number of lotteries offering the Megaplier to 37.
Generally, Powerball players do not have to choose cash or annuity unless they win a jackpot (then they usually have 60 days to choose.) Exceptions include Florida and Missouri; the 60-day "clock" starts with the drawing, so a jackpot winner who wishes to take the cash option needs to make immediate plans to claim their prize. New Jersey and Texas require the cash/annuity choice to be made when playing; in New Jersey, an annuity ticket can be changed to cash after winning, while in Texas, the choice is binding (when the cash option was introduced in 1997, all Powerball players had to make the choice when playing. This regulation was phased out by 1999.) All Powerball prizes must be claimed within a period ranging from 90 days to a year, depending on where the ticket was bought.
In spite of the huge popularity of this lottery draw game it is still an unknown to many that you can buy Powerball tickets online, whether you are in the US or not. To be clear, this doesn’t even mean that you have to be a citizen of the US either. No citizenship & not based in the US? You can still play powerball online and buy lottery tickets online for a number of different lottery draw games.
