When Powerball results are published
Powerball is drawn in the US on Monday, Wednesday and Saturday at 10.59pm Eastern Time: 3.59am UK time on Tuesday, Thursday and Sunday. Ticket sales close at 11.55pm the night before each draw. The winning numbers and the Powerball go up here as soon as they're out, and The National Lottery publishes its results from around 5am. In the UK each draw carries the date of the morning it takes place, a day after the American date.
Prize tiers and odds
There are 10 prize tiers in the UK, from 5 numbers and the Powerball, with odds of 1 in 292,201,338 per line, down to 2 numbers without the Powerball, with odds of 1 in 28.1. Match 5 pays a fixed £1 million and Match 2 a fixed £8; the other tiers share a part of each draw's UK sales among their winners, which is why their prizes change from one draw to the next.
The jackpot is shared with the US: if a UK ticket and an American one both win it, each gets half. Each tier is explained in Powerball prizes and the odds.
