Powerball
A bonus ball in certain lotteries that must be matched along with main numbers for the jackpot.
The term comes from the US Powerball lottery where players choose 5 main numbers plus a Powerball from a separate pool. Matching the Powerball alone or with some main numbers wins smaller prizes.
ExampleDrawing result: 7, 14, 29, 38, 52 with Powerball 6.
Bonus Ball
An additional number drawn separately from the main numbers that affects prize tiers.
Different lotteries call these Powerball, Mega Ball, Lucky Stars, or Bonus Ball. They typically come from a different number pool than main numbers and are required for the jackpot.
ExampleEuroMillions draws 2 Lucky Stars as bonus balls from numbers 1-12.
Multiplier
An optional add-on that multiplies non-jackpot prizes by a factor.
Games like Power Play (Powerball) or Megaplier (Mega Millions) multiply winnings 2x to 10x. The multiplier is drawn separately and costs extra per ticket. Typically does not apply to the jackpot.
ExampleWith a 3x Power Play, a $50,000 prize becomes $150,000.
