I think it's amusing that people wait until the payout is huge to buy a ticket; the odds DO NOT go up when the prize does! No matter how many people buy a ticket, your odds of winning DO NOT CHANGE. There are a specific amount of numbers that can only create a specific number of combinations. Have a mathematician explain it to you. Maybe the chances of SOMEONE winning goes up because more number combinations are sold, but the odds of a specific set of numbers winning never change! Perhaps if you buy all the number combinations.
