Those who play a lottery game regularly may be totally aware of what lottery rollovers are how they work. However, there may be some who do not and it is important to know that although the concept of lottery rollovers is simple, there are some rules that can vary depending on which lottery game you are playing. Lottery rollovers are created when the jackpot is not won, this then creates lottery rollovers as the prize is rolled over to the next draw creating a bigger jackpot. On some lottery games lottery rollovers can continue week after week for an indefinite period creating some of the largest jackpots in the world. However, some lotteries put a cap on either the amount of times lottery rollovers can happen on a game before it is guaranteed to be won. Others may put a cap on the amount that their lottery rollovers are allowed to reach.
The two US multi state games, MegaMillions and PowerBall are two games which allow their lottery rollovers to continue indefinitely. In fact both of these games have created the largest lottery rollovers ever to be won. The MegaMillions had a record breaking rollover win of $656 million in March 2012 and the PowerBall also hit the record books in November 2012 with the second largest American jackpot ever, worth $587.5 million jackpot. Lottery rollovers such as this could only be expected from games without any restrictions.
In the UK lottery rollovers work a little bit differently. The National Lottery rules that on the third rollover their lottery rollovers must be won and if no one matches the winning jackpot numbers then the jackpot is shared between those players who match the most numbers.
The Canadian Lotto Max has a cap of $50 million on its lottery rollovers. Once this cap is reached additional draws will take place offering prizes of $1 million each.
