J terms in the lottery glossary

Jackpot

The jackpot is the largest prize available in a lottery game. It is typically awarded to players who match all required numbers and is the main headline figure used to promote the draw.

Jackpot Rollover

A jackpot rollover occurs when no ticket matches all winning numbers, causing the top prize to increase for the next draw. This is how jackpots grow to very large amounts over time.

Jackpot Cap

A jackpot cap is a maximum limit on how large a jackpot can grow. Once the cap is reached, additional funds may be redistributed into lower prize tiers or special promotions.

Jackpot Estimate

A jackpot estimate is the projected prize amount shown before a draw. It is based on ticket sales and rollover conditions, and the final amount may vary slightly depending on actual sales.
