It’s easy: it’s a American multiplier! When added to your ticket, this has the power of doubling the value for any “not-for-life” prize you might win. For instance, if you hit the 3rd prize worth $5,000, or the 4th prize worth $1,000, but you have added the Doubler when purchasing the ticket, you will cash $10,000, respectively $2,000.
However, you should know that the Doubler does not have any influence on the jackpot or the 2nd prize. Their value remain the same, even if the winner decided to scoop the prize as a lump sum.
