DES MOINES — A nearly $1 billion Powerball jackpot will tempt lottery players today night who think they just might hit it rich after three months without a big winner.

No one has won Powerball’s $975 million jackpot since New Year’s Day, a stretch of 38 consecutive drawings without anyone matching the game’s six numbers. If no one wins the jackpot tonight or Wednesday night, the game will match its record number of 41 consecutive drawings on Saturday night.

The reason for the jackpot drought is simple: The odds of winning the top prize are miserable, at 1 in 292.2 million. It’s those odds that create the large jackpots that are designed to attract attention and drive up sales.

The $975 million prize is for a sole winner who makes the rare decision to be paid over 30 years through an annuity. Nearly all winners instead take the cash option, which for tonight’s drawing would be $471.7 million.

Powerball is played in 45 states plus Washington, D.C., Puerto Rico and the U.S. Virgin Islands.
