*a tip to know whether the website you are looking at actually buys lottery tickets online or follows the insurance model is to check the wording that they use. If you see the words “Play” then you can be confident it is a company that has agents and buys your tickets physically, if you see the words “Bet” you can be sure it is following the insurance model and you are placing a bet on the outcome of a lottery.
Jump up ^ Lotto, Lucy (June 30, 2011). "Powerball Lottery Changes for 2012". WorldLottery.net. Archived from the original on August 23, 2013. Retrieved September 4, 2013. The first and biggest change to the Powerball Lottery is the introduction of the $40 million base jackpot. Now, when the Powerball Lottery jackpot is reset after a win it will start at $40 million, tempting even more players in for those early draws. Another promise, that is sure to be popular with lottery players, is the introduction of more prizes. From January, Powerball players will have even better odds of winning a prize worth at least $1 million, and it’s that fact that may soften the third and biggest ever change. From January 15, 2012, Powerball Lottery tickets are doubling in price, in what is the biggest change to the Powerball Lottery draw since its launch in 1994.
In spite of the huge popularity of this lottery draw game it is still an unknown to many that you can buy Powerball tickets online, whether you are in the US or not. To be clear, this doesn’t even mean that you have to be a citizen of the US either. No citizenship & not based in the US? You can still play powerball online and buy lottery tickets online for a number of different lottery draw games.
