Seeing that some people win with just 50-200 tickets I decided to buy 500-1,000 tickets every lottery round, but it's hard to resist the urge of increasing your chances. So this time I bought 1,200+ tickets and ... yeah, I didn't win either. Not complaining because my chance of winning was less than 0.005% as far as I remember. I think I'll stick to under 1,000 tickets in the future with hope that I'll be extremely lucky one day.
