All lotteries have done the same though, and always you see the same effect. Hard promotion of the headline, jackpot figure and you will get people willing to have a punt. Make the jackpot smaller and enrich more winners, and paradoxically the number of players goes down.Strange but true.
Numbers of tickets sold in economic hard times almost always increase, because you are selling dreams, and hope to often desperate people for whom the lottery represents a real hope of life change. The marketing is all rather cynical and depressing really.
The largest proportion of players are those who can realistically least afford it, again because of the triumph of hope over expectation.
The odds of winning the lottery are fixed, but the size of the prize will vary according to the number of punters - more punters, more chance of sharing the prize.
