There was a dude who won 3 times this week and many other won 2 times. That's kinda unfair.
Where did you get the idea that
lottery should be fair? It is not. That is why it is called lot-tery, from french lot which means fate, luck, etc. Everyone can play it, there is no other factor than luck.
And btw I am no specialst in propability calculation and I don't know how the drawings are made, but I highly doubt that your chance of winning was higher when there was only 1 price.
