Yeah, lottery game is quite attractive, i've seen prizes go as high as 2 BTC(and/or more). and people have been lucky and winning with just few tickets, in the last round someone won .577 BTC with just 8 tickets. i manage to get 1k tickets every week, i think it's enough, all i need is luck to win a good prize. 
With the price increases, this weeks 1st prize of just over 1 BTC prize is far bigger than the 2 BTC prizes a month or so back. I think there are a lot of us hoping to get lucky when it gets to this time of the week. Fingers crossed for my 884 tickets.
