This was also possible in Poland last year or two years ago. The string of failed top prizes was so big that cummulated prize was so big in the end that buying tickets for all combinations was abt 2/3rds of the top one. This isn't gaming the system though its brute forcing it. And you are not guaranteed a profit. You bet against other ppl hitting the jackpot. Excluding oneself from the system, what is the chance that after N fails for top prize N+1 will also fail? Earning this way is not so easy as just winning the lottery.
