If you check their history of winners, then you can see one guy won the first price with just ten tickets. Winning lottery you should be very lucky that's it nothing else is required. If you're lucky then if you buy tonnes of tickets also you will never win the first price in a lottery system. Don't waste your money on buying a lot of tickets every week to win lottery.
some of my friends still curious to get these rewards and always bought some of tickets regularly even they said it doesn't matter being 10th winner as long as they can won the jackpot it will satisfied them and i think you're right that even the recent winner only have 8 tickets to got 1st prize so this is not about how much ticket do you have but this is about how much luck do you have to win the loterry
