Btw low number of lottery participants doesn't mean that the chance of winning the lottery increases because a lottery win is calculated by the number of coins that are collected via sold tickets. For example, if the number of participants and lottery tickets is high, the reward is high too but if they are low, then the reward decreases too.
No, there is no connection between the number of lottery tickets sold and the amount of winnings. In the weekly lottery the prize for first place is always $1,500 and for each subsequent place the prize is divided by 2, for second place the prize is $750, for third place the prize is $375 and so on.
