Multiple machines can be pooled together to make bigger and faster-growing jackpots, so when no wins the prize for a while, the total can grow to an insane amount. When won, the jackpot resets to a set amount, and gradually increases again. A fraction of the money from each spin is put into a pot that is set aside as a jackpot.
