DES MOINES, IA (AP) — Look for Powerball jackpots to get even smaller as the new coronavirus keeps more people at home, not out buying lottery tickets, officials said Thursday. It was only last week that the Powerball Product Group announced it would cut guaranteed jackpots in half and reduce the minimum amount the big prize could grow between drawings. On Thursday, the organization said it would toss out even those guarantees and instead decide new jackpots and increases prior to each drawing. Besides a drop in sales, declining interest rates also have limited the organization’s ability to fund bigger prizes. The leaders of Mega Millions, the other national lottery game, haven’t said if they will make similar changes to that game. Both games are run by state lotteries. Powerball and Mega Millions are played in 45 states plus Washington, D.C., and the U.S. Virgin Islands. Powerball also is offered in Puerto Rico.
