The last rounds winners though show us a different thing.They the people who have won the weekly lotteries do not have a huge balance nor they have bet huge amounts as to win like 1000-5000 lottery tickets you just need to have some like 10 WoF spin daily and you can get that amount within a week.
The reason we don't win is that out of 50 million users we need to be extremely lucky to be in the top 10 weekly lottery winners,chances in percentage as you can see in the lottery tab of the site is very but very low.
I really see no point in being excited by lottery results from years ago. It is like it was in the previous century.
As swogerino mentioned, the times has changes, I do not know how it was in the past, but probably now the lottery is really a secondary thing. I think most of people here, on the forum, has disabled tickets from free rolls; if someone has huge amount of tickets then it is probably from referrals.
