For example, the Guinness World Record for the largest online jackpot ever won is held by Microgaming's "Mega Moolah," which in 2018 won over €18 million. Because of the progressive nature of this double diamond slotsgame, a percentage of each wager goes toward the expanding jackpot, resulting in an alluring prize pool that has the potential to transform lives. Classic machines have become more and more popular because of their captivating gameplay and high payout percentages, in addition to progressive slots.
