The final 5/56 + 1/46 Mega Millions drawing was held on October 18, 2013; that night's jackpot of $37 million was not won. The first drawing under the revised 5/75 + 1/15 format—which saw the jackpot estimate "leap" to $55 million due to the change in the annuity structure—occurred on October 22, 2013. The minimum jackpot was then $15 million, with rollovers of at least $5 million. Second prize (5+0) became $1 million cash. In the revised format, players chose 5 of 75 white ball numbers, and the "Gold Ball" number out of 15.
The minimum Powerball bet is $2. In each game, players select five numbers from a set of 69 white balls and one number from 26 red Powerballs; the red ball number can be the same as one of the white balls. The drawing order of the five white balls is irrelevant; all tickets show the white ball numbers in ascending order. Players cannot use the drawn Powerball to match two of their white numbers, or vice versa. Players can select their own numbers, or have the terminal pseudorandomly select the numbers (called "quick pick", "easy pick", etc.).
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.
