I have been playing the same line for the past 10 years. I often get bored with one line and play extra lines knowing that the time horizon for winning the jp with one line is around 30,000 years.
The trouble with playing more lines is the fact that even if you played 100 lines per draw you could still be waiting up the 3000 years to hit a jp.
The good news is that if your holding a valid ticket lightning can strike and you can win on any drawing.
The phrase "you cant win if you dont play" is an advertising slogan that creates support for the state lotteries.
While it is true that you cant win (the lottery) if you dont play (the lottery)
It is also true that "only the stupid pay stupid tax".
