Lotteries are all about huge jackpots, so Lotteryguru.com monitors and updates the world's biggest jackpots and their respective draws to ensure that the site is always up to date. Note that Powerball and Mega Millions do not have rollover limits or jackpot caps, so carry on accumulating until all numbers are matched. The biggest lottery prize in history was the Powerball jackpot of 1.586 billion US dollars in 2016. The biggest ever Europian lottery, EuroMillions, has a jackpot cap of 200 million Euros, which is not bad either.
