Hoping to win the Powerball jackpot? Lottery officials just made the odds even tougher.

Powerball winners of yesteryear, rejoice: The odds were ever in your favor.

Starting October 7, that will no longer be the case for people playing the popular lottery game, thanks to a Monday change by New York's Gaming Commission, The Buffalo News reports.

Powerball players select numbers from two lines of possibilities. Up until now, the first line's field size has been 59 numbers, and the second has been 35 numbers. Officials changed the top field to a larger 69 numbers, and the bottom to a lower 26. So, people will have a better chance of guessing one number in the bottom field correctly, but picking all five correct numbers in the top field will be harder. The net effect, officials say, will be more partial winners — but fewer jackpot payouts. The odds of winning $1 million for correctly guessing the top five numbers and one bottom number will be 1 in 11.7 million, down from 1 in 5.1 million, for example. And the chances of winning a jackpot will fall from 1 in 175,223,510 to 1 in 292,201,338.
