To win first division Powerball, the winner must first win Lotto first division, and have the winning Powerball number on the same line. The prize for first division is very large: a minimum of $4 million, but with the chances of winning one-tenth of the odds of winning an equivalent prize in the main draw. Since April 2017 Powerball First Division can jackpot to a maximum of $50 million. Once the limit is met or passed, a "Must Be Won" draw must be held in which, if First Division is not won, the First Division jackpot must be split amongst the winners of the next highest division for which there are winners.
