What Is a Lottery Jackpot and How Does It Grow?
Quick answer: A jackpot is the first-category prize money that rolls over to the next draw when nobody matches the winning combination. Games like EuroMillions, La Primitiva, Bonoloto and El Gordo de la Primitiva have jackpots. A bigger jackpot does not improve your chances of winning: it only changes how much the winner would receive.

A jackpot is the top prize that rolls over to the next draw when there is no winner in the highest prize category.

If no one wins the top prize, the allocated prize money is added to the next draw, increasing the jackpot.
What happens when someone wins?
When there is one or more top-prize winners, the accumulated jackpot is awarded according to the rules of the game.
Do all lottery games have jackpots?
No. Each lottery has its own prize structure and rules regarding jackpot accumulation.

No. The odds of winning remain exactly the same regardless of the jackpot amount.
