How Lottery Jackpots Work
Lottery education is most useful when it makes probability, rules and risk easier to understand—not when it sells number-picking systems or implies a predictable edge in a random draw.
Top-prize pool
The jackpot is the top prize defined by the game rules. Its funding and advertised presentation depend on the lottery.
Rollovers
If no qualifying jackpot-winning ticket is sold, many lotteries carry some or all of the top-prize value into a later draw.
Multiple winners
Where rules specify a shared jackpot, multiple qualifying tickets divide the relevant prize pool.
