Up until now, there have been roughly 6 to 10 participants at any given time and a winner WAS guaranteed, so chances were very good. However as of the last contest, I was informed that the way winners were chosen could be gamed, so I altered it to this new system and I really have no idea how good the chance of winning is now. One would need 2 out of the 3 numbers to be in the correct place, but there could be 6 possible numbers in each position. Whatever odds that works out to.
